The largest diamond ever found in Angola has been discovered recently in Lulo mine. The lucky finder was Lucapa Diamond Company – Australian company, which specializes in diamond mining.
A 404.2ct diamond became the 27th largest in the world. It was given type IIa, which is the second highest rating existing for such gems. Only 2% of all diamonds in the world were given the same rating. It makes the stone extremely rare and precious.
The price of this wonderful stone estimated by Lucapa Diamond Company is over $20 million. Now it is the biggest diamond found in Angola, breaking the record of previous champion – the Angolan Star with its 217.4cts.
Forbes reports the Lucapa Company plans to see the stone to finance the examination and enhancement at their diamond mine in Angola.

Open pit mines
The satellite radar interferometry technique derives information about surface deformation within area of open pit mines
The main problem that can occur during mining works within open pit mines is the issue of scarp stability. In order to improve the process of exploitation, the areas of particular vulnerability to landslides have to be recognized as well as the initial phase of surface deformations must be detected. The monitoring of subsidence caused by changes in the groundwater level in the foreland of the excavation pit is also very important. The ground deformation monitoring within open pit mines can be done using satellite radar interferometry and polarimetry methods.
The DInSAR (Differential Interferometry Synthetic Aperture Radar) method can be used to detect ground deformation that occurred within the study area in particular period of time. In turn, the use of radar polarimetry methods PolSAR (Polarimetric SAR) allows detecting changes in the nature of a radar wave reflection. Such changes can be correlated with the occurrence of landslides.
At SATIM we offer ground deformations monitoring within open pit mines.By using satellite radar interferometry and polarimetry methods it is possible to obtain results with high spatial and temporal resolution as well as high-precision of deformations measurements.

Reduce Maintenance Requirements with ROXDUR Wear Resistant Technology
In any industry with heavy machinery, there is an inevitable conflict between the processed materials and the machines capacity to withstand high volumes. The mining industry encounters this conflict more so than any other; breaking, excavating, hauling and transporting some of the Earth’s strongest raw material.
The sheer mass of this material is enough to create expensive maintenance requirements and even more damaging, can create unplanned downtime that halts mine site production and consequently reduces profitability. So how do mining companies protect their equipment against wear and abrasion?
Wear material and impact absorption technology play a key role in the fight against abrasion, the premise being to ‘fight hard material with even harder wear protection’. The aim is to extend the life of machinery by adding coats of wear protection that act as armour against raw materials.
These layers of armour face the strongest points of abrasion and are replaced when they no longer create resistance. Whilst they may provide short term costs, they provide a long-term alternative that proves to be cost-effective when comparing the price of replacing entire machines/equipment.
A study by VTT Technical Research Centre of Finland revealed that 40% of the consumed energy in mineral mining worldwide, is used to overcome friction with an additional 17% used to remanufacture and replace worn out parts, or stock spare parts. That equates to an estimated 210 000 million euros of economic loss as a direct result of wear, every year. New technology designed to create harder, more effective wear resistance is expected to reduce this financial outpour by 30% in the long term, proving that wear material has a permanent place in the mining industry.
As the necessity to integrate wear material on-site becomes increasingly apparent, ROXON’s engineering team have combined industry knowledge and research to create a unique material that promises to deliver an armour of extreme hardness to combat against machine damage. Layers of cemented carbide are combined into an iron matrix to deliver a metallurgical bond capable of withstanding the highest levels of impact. A range of products has been designed to integrate into any application, specifically in areas with limited access.
To reduce financial loss mining companies must continue to respond and protect against wear and abrasion by incorporating the newest, and hardest wear resistance technology. ROXDUR’s newest iron matrix carbide is proven to provide up 20x longer wear life for machinery, to increase profitability and reducing maintenance requirements.
ROXDUR Product Manager Oskar Larsson adds ‘the largest asset in any company is there ability to create efficient, cost-effective solutions – ROXDUR provides the leading answer in addressing machine wear, delivering a return on investment far greater than previously seen by alternative products’.

Exploration of minerals should gather momentum: Mines Joint Secretary
Parda Phash , Aug 18, 2018
According to the information given by the Mines Ministry official, Government is likely to announce the draft National Mineral Policy after giving the final touch. The mines Joint Secretary Bipul Pathak said that the exploration of minerals should gather momentum and get double every year.
Bipul Pathak went on to say: “The new policy aims to give a big boost to exploration activities. In three to five years, the exploration of minerals should gather momentum and double every year.”
Pathak was speaking at a National Summit on Mineral Exploration and Sustainability, organised by industry body FICCI and International Institute of Corporate Sustainability and Responsibility (IICSR).
Responding to industry’s concern over high taxes, the new policy will take cognisance of the recommendations on royalties and other levies to put a liberal regime in place, he said.
Pathak urged the private sector to step up investment in mineral exploration and assured industry that the government will extend financial and other support to junior exploration companies developed by the private sector.
Explaining the reasons for the lack of private investment in the sector, Vedanta Director Kishore Kumar called for making exploration blocks sustainable through offer of larger blocks and mining rights to companies doing reconnaissance work.

WMC 2023 will soon be calling for abstracts for oral and poster presentations that align with the following future-focussed themes:
Digital mining leverages the best of digital and automation technologies to connect the entire mine value chain. Key focus areas include interoperability, sensors and communication, real time data capture, sorting and visualization, automation and robotics, integrated and remote operations, machine learning and artificial intelligence, digital twins, and cognitive networks.
Value chain optimisation has moved from silo-based decision making to a fully integrated systems approach. Implementation of Mining Industry 4.0 requires profound cultural and technical changes, with key focus areas including value chain analysis and integration, systems engineering, mine-to-port optimisation, data analytics, and intelligent remote operations, using cyber-enabled real-time data analysis and decision making, harnessing robotics, automated haul trucks and drilling rigs, UAVs, remote operating centres and predictive equipment maintenance systems for asset tracking and life-cycle management.
Mining is distinctly different from other industries, given the variable and uncertain nature of ore bodies, flowing through to continuous extraction, processing and transportation systems. Modern day sensors make capturing real-time data easier, the deployment of internet of things (IOT) sensors around different stages of the mining value chain is becoming a reality.
Autonomous Systems content.
Sustainable practices are at the core of the mining industry’s license to operate. Key aspects include environmental impact, resource and water scarcity, and closure rehabilitation and circular economy.
Climate change is one of the greatest challenges of our time. There are major emerging risks due to climate change and the transition to a lower carbon economy, that range from risks resulting from increased severity of extreme weather events, to that arising from a variety of policy, legal, technological and market responses. Opportunities for innovation are equally significant and include decarbonisation, energy efficiency improvement, use of renewables, fugitive emission reduction, carbon capture and storage (CCS), and climate adaptation.
Environmental Sustainability content.
Social licence to operate is not a cost to mining, nor a transactional process, but an imperative. More broadly, our sector’s connection to the wider community remains a central component for the sustainability of our industry. Key focus areas include social research, workforce, community and stakeholder engagement and measuring social performance.
Critical Strategic Minerals content.
Discovery and extraction activities are increasingly extending to focus on deep onshore, undersea and space mining. These activities are driving the development and implementation of cutting-edge technology, and inter-discipline and inter-industry collaboration that will advance traditional mining processes to provide the resources necessary for the future.
In addition to the technology front, how will the current industry standards for reserve and resource estimation and reconciliation need to be modified to address undersea, deep on-shore and off-planet mining.
Education and skill requirements are increasingly demanding as mining technologies, and its physical, social/political operating environments are changing. As more technology is introduced into the sector the competencies and professionalism of the workforce becomes more, not less, important.
To adequately resource the future there needs to be greater focus on primary, secondary, tertiary and vocational education and pathways, continuous professional development, currency and professional mobility, inclusion, identity and cognitive diversity, development of the indigenous workforce, remote and digital delivery, international mining education collaboration, and strategic cooperation between the education sector and industry. Topics of interest also include strategies to attract a future digitally skilled workforce.
‘Zero Harm’ is a non-negotiable for the modern mining sector and the minimum standard for all operational decisions. Key focus areas include mine fires and explosion, rock bursts, coal and methane outbursts, rock falls, ground water ingress, failures of underground and surface mine infrastructure (e.g. tailing dams), mine emergency management and rescue.
Health topics of particular interest include dust, thermal stress, noise, diesel particulate matter, fatigue, anxiety and mental health.
The industry is faced with significant challenges to meet growing energy and resources demands worldwide. Over the last decade resource discovery has not kept pace with extraction and exploration expenditure has been in decline. To reverse this trend we need new data acquisition techniques and geoscience knowledge to support mineral exploration, to reduce the technical risks of exploration by providing pre-competitive data and to boost resource discovery rates. Key focus areas include exploration under deep cover, attracting exploration to frontier or greenfield regions, data collection and synthesis to unravel the fingerprints of ore-forming systems, characterisation to inform exploration, ore body knowledge, and modelling supported with artificial intelligence.
Efficient mine operations require greater advancement and application of geophysics, structural geology, engineering geology for reliable mine characterisation for geological, geotechnical and geohydrological conditions.
As the complexity, depth and scale of mining operations increases, the mining processes and associated equipment needs to evolve to meet the needs of remote and autonomous operations. This results in new challenges emerging for the mining sciences, METS and engineering functions.
Key mining science focus areas include rock mechanics, geotechnical assessment, hydrogeology, mine ventilation, gas emissions, ground control, slope stability, block caving, rock drilling and cutting. Key technological areas include latest technologies and innovative solutions for surface and underground mines of all minerals, from coals to metals, from construction materials to rare earth elements. Key mine design and planning areas are mine design methodology, short, medium and long-term mine planning, sequencing and scheduling, equipment selection, and infrastructure (rail, plant, and port), as well as mine approval processes, mining economics, capital allocation, and commodity end uses.
Other key focus areas are commodity market analyses, resources and environment policy, mining legislation and regulations, reserve and resource estimation, mine feasibility studies, capital-raising and investment, and mine planning. Sound resource and environmental policy is needed to support and enhance the business environment and prospectivity for mining.
Continuous improvement and innovations are required in the extraction, processing and refining of minerals to increase mineral recovery, selectivity and efficiency, reduce water and energy use, and minimise waste and environmental impact. Comminution is on average the highest energy step in the overall mining process (around 50%) and consumes up to 3% of all electric power generated in the world. Key areas of focus to reduce energy consumption are the use of geometallurgical models, mineralogy, characterisation, ore sorting and pre-concentration, new grinding techniques, plant design and in-situ processing and recovery.
Other key focus areas include hydrometallurgy, pyrometallurgy, water management, tailings and other waste and hazard management, rare earth elements processing, plant design and optimisation, mine to mill integration, intelligent plants, dry processing, and plant maintenance.
This theme also incorporates plant operations, practices and management, emerging technologies, instrumentation and sensors, automation and process control and data analytics. Importantly processing doesn’t end with a concentrate, but incorporates refining, recycling, reprocessing, metal accounting, reconciliation, and product marketing and specifications.

A manufacturer of mining and industrial mineral processing equipment sued a manufacturer of related replacement parts for trade secret misappropriation. The technology at issue related to conical crushers, which are heavy equipment used to reduce rocks to a size that is acceptable for a specific application.
Intensity calculated economic damages relating to claims of trade secret misappropriation. Intensity also evaluated reverse engineering effects, capacity constraints, and related market conditions that may have impacted trade secret damages in the case.
As part of determining trade secret damages, Intensity evaluated whether the trade secret technology provided a “head start” in the development and commercialization of accused conical crushers. Intensity evaluated economic considerations under various development scenarios and calculated trade secret damages under five different scenarios relating to lost profits on lost sales of crushers and replacement parts. Intensity also evaluated applicable royalties.


July 3, 2019 - GGX Gold to Test New Technology on A Newly Discovered Geophysical Anomaly - See GGX News release
"Stargate II surveys were performed by ESSCO over the Republic Graben trend in Washington and B.C. in 2014/2015 at 1 km and 500 metre line spacings. A resultant geophysical anomaly on the Gold Drop property in the Greenwood Mining Camp was supplied by Glenn Galata of ESSCO. The anomaly measures 1834 by 1377 metres, is centered at the intersection of three interpreted major fault conduit structural traces and is located along strike and to the north of the C.O.D. vein trend. Testing the target will require drilling to a depth of at least 400 and up to 764 metres – the deepest ever to be drilled on the Gold Drop property."


At least eight coal miners were feared dead after the rainwater that flooded the coal mine in Jhimpir in Thatta district on Tuesday night could not be pumped out till Wednesday evening, according to district administration.
According to a private TV channel, the rainwater accumulated 50 to 60 feet inside the mine, which is located around 8 kilometres away from the Meting railway station. The district administration had deployed six pumping machines to drain out the water, but in vain.
The Thatta deputy commissioner said that some 40 workers were involved in mining work despite the rainy season. He added that eight workers were still trapped inside while the others had come out before the incident occurred.
No bodies were retrieved till Wednesday evening because the mine was still filled with rainwater, according to the Thatta DC. The Hyderabad divisional commissioner said that the mine was filled with around 11 feet deep water.
Rangers personnel and police had been rushed to the site for assistance in rescue works, according to the media report. The Hyderabad divisional commissioner said that the assistance of the Navy had also been sought to retrieve the bodies.


ADELLA HARDING Mining Correspondent
With all the mining plans and exploration plans for SSR Mining Inc.’s Marigold mine, which has been in production in Nevada since 1989, mine general manager Don Dwyer said he sees “no reason to which we wouldn’t be here another 30 years.”
Marigold’s facilities are five kilometers south of Interstate 80 in Valmy, and current mining operations are nearby, but Marigold’s properties include Trenton Canyon and Buffalo Valley, where exploration is underway or planned. for potential future use.
SSR Mining plans to spend $24 million on exploration at Marigold this year.
“We secured the rigs earlier in the year,” Dwyer said.
Plans also include starting engineering studies at Trenton Canyon to “basically help us understand how big the pits would be,” as well as where the heap leach pads or a new waste rock dump would go and to from there to figure out how operations at Trenton Canyon would add to the life of the mine and start the permitting process, he said.

Newmont Corp. operated Trenton Canyon years ago, and there is an old building on the site that houses the North Peak carbon columns and an office trailer, but Dwyer doubted they would be used in new operations. Newmont’s clearance could facilitate new licensing efforts for Trenton Canyon, he also said.
“We’re likely to build a new heap leach facility at Trenton Canyon and carbon columns and bring the carbon back to Marigold, which is about a 25-minute drive,” Dwyer said.
Buffalo Valley is still 20 minutes south of Trenton Canyon, so it would be an even longer return to Marigold. Buffalo Valley has a small open pit from a former production.
Stewart Beckman, executive vice president and chief operating officer of SSR Mining, said on the company’s first quarter earnings call that “we are getting new drilling at Buffalo Valley that we are excited about and also at Trenton Canyon. which is a bit different from what we had previously thought….
Exploration drilling at Trenton Canyon includes examining deep sulphide ores, “but the majority of what we drill is oxide ore that we can currently leach in heaps,” Dwyer said.
The Marigold mine life is now 2032, but this does not cover the potential of Trenton Canyon and Buffalo Valley, as well as the possibilities at the current mine site, where current mining is in the Mackay complex.
Dwyer said mining is ongoing in the complex at Mackay 4, 5 North 2 and H1 in the northern part of the pit, and all ore is trucked to a heap leach pad. without going through a crusher or going to a mill.
“Basically we blow it up, and it goes to the heap leach pad on its own,” he said, and the ore from the pads later goes to the carbon columns, and the gold from there goes through an electrowinning circuit, the retort system and then to the foundry to be cast into gold bars.
At the leach pads, Marigold has completed construction of Cell 19B and is “currently stockpiling ore on this cell, and this year we will begin construction of Cell 23A,” Dwyer said.
Meanwhile, the US Bureau of Land Management’s Winnemucca office is in the midst of an environmental assessment for the Valmy expansion, which covers a series of older pits that Marigold is seeking to expand. These include the Mud, Valley and New Millennium pits. New Millennium itself was an extension of the old Antler and Basalt pits.
“We will start in the Mud Pit in 2025, and the others will come later in the life of the mine,” Dwyer said, noting that there is ongoing exploration to expand New Millennium and add to the life of the mine. of Marigold.
According to Denver-based SSR Mining’s earnings report, Marigold produced 33,788 ounces of gold in the first quarter, compared to 67,936 ounces in the first quarter of 2021 due to mine scheduling and increased production. heap leach inventory that delayed some gold production. in the second quarter.
Heap leach inventory has increased due to when ore is placed on the leach pads and slower leach rates of finer ore from the northern pits, the report said.
SSR Mining also said Marigold remains on track for a production forecast of 215,000 to 245,000 ounces of gold in 2022, with most production coming in the second half. Beckman said the fourth quarter will be the best when higher grades are processed.
Dwyer said “we will be extracting higher grades from the H1 pit.”
All-in sustaining costs for Marigold averaged $1,564 per ounce in the first quarter, compared to $1,195 in the 2021 quarter, but the company said costs will improve in the second half.
Marigold has 450 employees, and “the goal is to get to just over 460,” Dwyer said, adding that two-thirds of employees come from Winnemucca and the rest from Battle Mountain, and many are long-term employees. .
Ralph Erquiga celebrated his 40th birthday at Marigold this year. He was a process manager, but he became a capital project manager.
“You don’t often find that people stick with a company for that long,” Dwyer said.
“Overall, at Marigold, we really try to embrace people and culture, and our turnover rate is lower than our peers because we’re focused on people,” he said.
Marigold’s fleet includes 25 Hitachi and Komatsu 320-ton haul trucks, a P&H electric shovel that handles about two-thirds of the mining, and four hydraulic shovels. Dwyer said Marigold is slowly replacing Hitachi excavators with new Komatsu excavators.
Reclamation over the years has included backfilling the pits, and Marigold is currently backfilling the Mackay 3 pit and the 5 North 1 pit.
Marigold is also going dry for the first time in all its years of operation, with four active wells and three more wells to come. The current dewatering rate is less than 2,000 gallons per minute and Marigold will build rapid infiltration ponds this year, Dwyer said.
Currently, water is discharged into Cottonwood Creek under a temporary discharge permit.
Dwyer said the dewatering “allows us to access ores deeper in the Mackay pits in the Red Dot area on the west side.”
The BLM issued a decision record in October 2019 allowing dewatering up to 10,718 gallons per minute.
Marigold has also continued to work on improving safety at the mine since a double fatality in 2017 which was the first for the mine, and Dwyer said there has been a decline in injuries. In fact, the Nevada Mining Association awarded Marigold eight individual safety awards last year, the most of any mining company in the association, he said.
The Mackay complex is named after the Mackay School of Mines at the University of Nevada, Reno, and UNR is one of the major royalty holders in this area of the Marigold mine. The university receives a royalty from mining at Mackay.
SSR Mining, which was called Silver Standard Resources before shortening its name to SSR Mining, bought 100% of Marigold in 2014, and the company merged with Alacer Gold Corp. in 2020. The Company’s other operations include the Seabee underground mine in Canada, the Copler mine in Turkey and the Puna silver mine in Argentina.
According to the technical report on Marigold prepared by OreWin and published in February, Marigold’s first recorded gold production dates back to 1938 from an underground mine, and approximately 9,000 tons of ore were processed before the shutdown. production by World War II.
Several unsuccessful attempts were made to reopen and operate the mine before exploration activities resumed in 1968, the report said. From 1968 to 1985, several companies explored the Marigold area, and in 1986 a joint venture was formed between a subsidiary of Santa Fe Pacific Railroad and the Cordex Group. They consolidated some land holdings.
A production decision was made in March 1988 on the 8S deposit, and in August 1989 the first gold bar was poured at the Marigold mill, the report said.
Rayrock Mines, Cordex’s operating company, bought two-thirds ownership of Marigold in 1992, and Homestake Mining Co. held the remaining stake until Barrick Gold Corp. absorbs Homestake, then owns one-third. ￼


Mining activities are critical for industrial concerns. Largely, mining resources provide energy that is necessary for sustaining the needs of societies. Production of plastics and fertilizers rely on oil extractions. Military technologies utilize uranium sources in the production of nuclear weapons, signifying the relevance of mining in providing homeland security. Renewable energy resources offer environmental-friendly energy sources; however, the infrastructure required to construct the alternative energy installations relies on consumption of rare metals meaning that their demand will increase significantly (André-Mayer 1). Therefore, sustainable practices have to be developed to ensure that cities recycle resources used.
The relevance of any mining expedition is calculated according to the energy ratio achieved. The Energy Return on Energy Invested (EROEI) concept is used to calculate the energy returns to maintain the viability of the mining venture (Ahmed 1). Essentially, the global mineral resources are plentiful; however, mining activities rely on extractions from concentrated sites that offer a reliable EROEI. Recent developments in mining expeditions signify a growing concern in rising needs for energy resources used in mining due to a reduction of easily accessible mineral resources.
Technological innovations such as fracking have limitations since the productivity they offer only run within three years of operation at a site, prompting exploration of many wells at the expense of the environment. Methane is used in the fracking process, and approximately four percent is released to the atmosphere (Environment 1). Taking into consideration that the heat-trapping effect of the gas is twenty-five times stronger than that of carbon dioxide, fracking activities have devastating effects on the atmosphere.
Furthermore, the fracking process relies on the availability of massive amounts of water which has to be sourced from lake, rivers or neighboring communities. Wastewater from the chemical processes involved in Hydraulic fracturing activities has toxic elements that undermine the ecosystem when released to the ground (Greenpeace 1). Lastly, sinkholes and soil contamination are other implications of mining on the environment.

A Fire At A Coal Mine In Russia’s Siberia Region Has Killed At Least 11 People And Left Several Others Missing.
According to Russian media, local grower Sergei Tsveliv said that there were 285 miners in the mine at the time of the accident. 200 people have been rescued in the rescue operation.
Authorities say 45 workers were injured in the blast. The condition of several miners deteriorated due to smoke filling in the mine.
According to officials, rescue operation is underway to rescue the remaining people trapped in the mine. There is no contact with the miners trapped underground.
The government has not yet commented on the nature of the accident. But it is worth noting that 13 workers were killed in a methane gas explosion at the mine in 2004.


This is for Iron Mining Nodes, separate from Iron Veins
- In order to harvest this Resource, you require a minimum Mining level of 25
- This specific Deposit only requires an Iron Pickaxe to harvest it.
- Co-ordinates needed for Alternate locations, although not priority.
- Locations Posted are Exact coordinates of the Node, not just where you need to stand.
Other than the Mining Guild at higher Levels, the easiest place to mine Iron Ore at low levels is the Skeleton Dungeon, East-South-East of Dorpat Town, West of Dorpat Outpost.
The Iron is surrounded by Lv36-44 mobs, however there is a path between the mobs to get to the Mining Nodes without fighting. Be aware that there are two kinds of Mining Nodes that give Iron Ore, they are Iron and Iron Vein, the difference between them is that the Iron is mine-able by the Iron Pickaxe whilst the Iron Vein requires a Steel Pickaxe.

How many tons in a cubic yard of rock & stone | How many tons of rock are in a cubic yard | How many tons per cubic yard of rock | how many tons is 5 cubic yards of rock | how many tons in a cubic yard of stone.
1 cubic yard of rock look like by 3 feet long by 3 feet wide by 3 feet height as equal as 27 square feet (length× wide× height).
Weight of one cubic yard of rock vary depending on the shape of the grains, size of the grains, the material content, its crystalline nature, its density of grain, mineral factors, wet and dry condition, loose sand, compacted condition.
Rock is a granular material composed of small rock, gravel, finely divided fragments of sedimentary, Metamorphic and igneous rock with mineral particles. size of rock ranging from 5mm to 256mm, as finally divided Rock, coarse aggregate, very coarse aggregate, peebles, cobbles and boulder.
Rocks eroded or weather over a long period of time mainly by water, wind, alkaline and acidic effect. Their eroded parts or sediment transported along the downstream, it sediments even broken into a smaller pieces and till they become a fine grain of sand.
You are looking to buying rock and crushed stone for your construction work, prepairing of concrete mortar, you need to know how many tons in a cubic yard of rock and you should purchase and you can load in your vehicle.
Most of rock supplier which are available nearly to you, will give you option to deliver sand and crushed stone at your homes, for this they should cost some money for transportation. If you have a truck or vehicle that you can use to bring sand to your destination or construction site, then it is cheaper and faster option for you.
How many tons in a cubic yard of rock
Weight of rock depends on the rocks type, loose and dense condition, compact, moisture content, dry and wet condition, small rock, gravel and others inorganic mixed in the rock. For estimating purpose, contractor’s and Builder’s would take weight of rock as 3000 lb/yd3 or 1.5 short tons per cubic yard and 110 lb per cubic feet.
A cubic yard of rock equal as 3000 pounds, A short ton weighs around 2000 lbs, so number of tons, 3000/ 2000 = 1.5 short tons, in this regard, “how many tons in a cubic yard of rock”, so, generally there are 1.5 short tons of rocks in a cubic yard. This is standard weight of rock in tons per cubic yard used for billing purpose.
How much is a yard of rock:- as per material you choose, expect to pay $20 to $100 per cubic yard of landscape rock or stone, or $0.75 to $4 per cubic foot. Landscape rocks are an aesthetically-pleasing and cost-effective choice for a wide variety of projects, including stone and gravel driveways, patios and walkways, and retaining walls.
In this regard, “How many tons of rock are in a cubic yard”, according to Imperial or US customary measurement system, based on size, compostion, dry and wet condition, for estimating purpose of rock, generally there are 1.5 short tons/ tonnes of rock are in a cubic yard. This estimate are used for calculation of required rock quantity by contractors and Builders and useful for common people for better understanding.
Typically, 1 cubic yard of rock yields about 1.5 tons, for 2 cubic yards, it will yield about 3 tons of rock, for 3 cubic yards, it will yield about 4.5 tons of rock, for 4 cubic yards, it will yield about 6 tons of rock, for 5 cubic yards, it will yield about 7.5 tons of rock and for 10 cubic yards, it will yield about 15 tons of rock.

How many tons in a cubic yard of stone
There are 1.5 tons in a cubic yard of rock or stone. A cubic yard of stone weighs 3000 pounds and a ton of rock weighs 2000 lbs, so number of tons in a cubic yard of river rock 3000/ 2000 = 1.5 tons. This is standard weight of stone in tons for one cubic yard used for billing purpose.
How much does a yard of rock weigh
A cubic yard of river rock, which visually is 3 feet in length by 3 feet wide by 3 feet high, used in landscaping (1″-3″ size), will weigh anywhere between 2,400–2,700 pounds and is equivalent to 1.2 to 1.35 tons. Typical rock will cover approximately 100 square feet per cubic yard or 80 square feet per ton at standard depth of 3 inches.
Generally, there are 1.5 tons of stone or rock or gravel in a cubic yard. For billing purpose a yard of rock weighs 3000 pounds and 1 ton of rock weighs 2000 pounds. So, number of tons in a yard of rock = 3000÷2000 = 1.5 tons. Thus, there are 1.5 tons in a cubic yard of rock, or stone.

With a reserve estimated at 350 million carats, the work of geological prospecting and geophysical survey of the mine began in 2008, which later led to the discovery of kimberlite in 2009.
The mine will occupy an area of ??100 hectares and was projected to reach the depth of 400 meters.
Speaking to the press at the end of the visit to some mines in Lunda Norte, Ganga Junior reported that the large sample of the Luaxe kimberlite material is being treated at Catoca (the largest diamond company in the country and the fourth largest kimberlite in the world) .
He emphasized that the contents that had been predicted are confirmed and now the technicians will examine and determine the value of the stones.
Subsequently a feasibility study will be conducted, as well as specific projects of construction of the structures of the mine will be undertaken.
He disclosed that the mine goes into full operation in late 2021 or early 2022.
Meanwhile, small-scale production will be done later this year with the structures of the Catoca Mining Society, which is 25 kilometers off the Luaxe mine.
Ganga Junior recalled that the prediction for the diamond subsector this year is to produce 9.5 million carats, which will allow a turnover of 1.3 billion US dollars.

2013 killed at least 1,000 people in coal mine accidents in China.
Chinese state media said at least 22 people were killed in an accident at a coal mine in the Southwest.
Reports says that the accident was caused by an explosion.
Last year, died or disappeared at least 1,000 people due to accidents in Chinese coal mines.
However, the number of accidents was reduced by 20% compared with 2012.
A mining accident is an accident that occurs during the process of mining minerals. Thousands of miners die from mining accidents each year, especially in the processes of coal mining and hard rock mining. Most of the deaths nowadays occur in developing countries, especially China and rural parts of developed countries.
Mining accidents can have a variety of causes, including leaks of poisonous gases such as hydrogen sulfide or explosive natural gases, especially firedamp or methane, dust explosions, collapsing of mine stopes, mining-induced seismicity, flooding, or general mechanical errors from improperly used or malfunctioning mining equipment (such as safety lamps or electrical equipment). Use of improper explosives underground can also cause methane and coal-dust explosions.
On April 26, 1942 in the Benxihu (Honkeiko) Colliery (coal mine), what is believed to have been the world's worst mining disaster took place, killing 1,549 miners. The disaster occurred in an area that is now within the bounds of modern-day China, but was then in a portion of China occupied by the Japanese, just north of present-day Korea. The Japanese administrators of the mine had the actual mining work performed by forced Chinese labor under harsh conditions. The disaster first began with a mine fire, but at the time, a hasty decision was made by the Japanese mine operators to promptly cut off the ventilation and to completely seal off the mine to kill the fire. This reportedly left many unevacuated workers still alive within the sealed-off area of the mine to eventually also suffocate. Once the fire was put out in this manner and the mine re-opened, it took 10 days to remove all of the bodies. Of those killed, 1,518 were Chinese, and 31 were Japanese. Afterwards, several bodies were buried in a mass grave. According to a followup investigation carried out by the Soviet Union, the majority of the fatalities were not caused by the initial fire, but instead were the result of secondary carbon monoxide poisoning and suffocation.

2 Bodies Spotted By Navy Divers In Meghalaya
2 Bodies Spotted By Navy Divers In Meghalaya. Meghalaya Chief Minister Conrad K Sangma on Tuesday stated that divers of Indian Navy, who’re engaged in seek and rescue operation at an unlawful coal mine in East Jaintia Hills district, have noticed our bodies.
At least 5 miners have been trapped in the coal mine in Sutnga Elaka on account that May 30. The mine became flooded after a dynamite explosion.
“We have acquired a initial document that they have got noticed our bodies however it’s far but to be showed in writing,” Mr Sangma stated on Tuesday.
Personnel of the National Disaster Response Force (NDRF) and diverse nation businesses too have been worried withinside the operations and had waited for the water degree to return back right all the way down to approximately 10 meters withinside the 152-metre deep pit.
Police have arrested the proprietor of the coal mine and charged him for violation of the inexperienced court’s order banning unscientific mining and transportation of coal.
The National Green Tribunal (NGT) had in 2014 imposed a blanket ban on rat-hollow coal mining throughout the nation. But still, unlawful mining is taking region withinside the nation in violation of the order, officers stated.
Meghalaya is predicted to have coal deposits of approximately 560 million tonnes.
The indiscriminate and unscientific mining, absence of post-mining remedy and control of the mined regions are making the delicate ecosystems greater prone to environmental degradation.

About Himalayan Rock Salt
The main centre of mining is “Khewra” Salt Range which is the world’s 2nd largest salt mine. Its history dates back to its discovery by Alexander the great’s troops in 320 BC, but it started its operations in the Mughal era. The main tunnel at ground level was developed by Dr. H. Warth, a mining engineer, in 1872 during British rule.
After independence, the Pakistan Mineral Development Corporation took over the mine, which still remains the largest source of salt in the country, producing more than 350,000 tons per annum of about 99% pure halite. Estimates of the reserves of salt in the mine vary from 82 million tons to 600 million tons. Now in 21st century Himalayan Rock salt present as craft items for various kind of uses.

. In this blog, we will talk about the following:-
- What is Rotary Drilling?
- History and Current Technologies of Rotary Drilling.
- General Rotary Drilling Methods.
- Types of equipment and Rotary Drilling components.
- Advantages of Rotary Drilling Rig.
What is Rotary Drilling:
Rotary Drilling refers to the use of sharp, rotating drill bit to cut or crush by applying downward pressure. It is mostly used to drill big holes in pit mines, petroleum extraction and other various fields. To gather information about coal deposits drilling is the most trusted and reliable method. Before drilling, coal prospecting is done to discover coal resources through search.
- Rotary drilling is a general method in drilling in which a string of drill pipe is hung from a derrick and turned by the engine.
- Rotary cutting is also used to drill small boreholes in soft rocks.
- For medium to hard rocks, rotary crushing is used.
- Ai rotary drilling is used to drill deep boreholes in rock formations.
One of the crucial factors with the drilling program is to do selection between core drilling and rotary drilling.
Current Technologies and Innovations:
- New technologies have reduced the environmental impact of energy production by allowing more oil and gas.
- Discovery of new resources plays a crucial role in meeting global energy demand.
- Technological Advancements are used for well drilling and completion have enabled energy industry to reach new sources of oil and natural gas.
- Companies can push length in excess of 3,000 meters as compared to 30 meters a few decades back.
- Horizontal drilling is a directional drilling process which provides more contact to reservoir formation than a vertical well and allows an increase in the production of hydrocarbons.
- When oil and natural gas are in separated layers, multilateral drilling allows to branch out from main well to tap reserves.
- When vertical well cannot be drilled, Extended reach drilling allows producers to reach deposits that are great distances away from a drilling rig.
General Rotary Drilling Methods:
Drilling method varies from digging with tools to high-speed drilling with types of equipment. Small to medium-sized drilling rigs are mobile, such as those used in mineral exploration drilling, blast-hole, water wells. Larger rigs can drill thousands of meters of Earth crust, using large “mud-pumps” to circulate drilling mud through the drill bit.
- To drill deep boreholes in rock formations, air drilling is used.
- Circulating air is used in this method to cool drill bits.
- By rapid rotation of drill bit, borehole advancement is achieved.
- Several variations in air rotary techniques includes air rotary casing hammer(ARCH), down hole hammer and under reaming.
- In ARCH, often called “top drive”, both rotational downforce and impact force are provided by an above-hole impact hammer and a rotating drill head.
- Under reaming is a variation of the top drive casing advancer method that uses a rotating cutting bit in front of the advancing casing.
- Drill bit cuts the formation into small pieces, called cuttings.
- These cuttings are removed by pumping drilling fluid through drill pipe called mud.
- The drilling fluid is also used to cool the drill bit and stabilize the borehole wall, prevent fluid loss into the formation.
- Mud rotary is often used in soft sediments that may or may not be saturated with groundwater.
- Unlike other drill rigs which use only an upper drive, dual rotary uses both an upper and a lower head drive to advance the drill bit and casing.
- Dual rotary technology delivers powerful performance in unconsolidated overburden (sand, gravel, cobbles, and boulders) where other technologies struggle to drill a cased hole.
- A top drive rotary head simultaneously handles a drill string equipped with either a down hole hammer, drag bit or rolling cone bit to drill the centre.
- In reverse circulation, rotational and impact energy are delivered in the same manner as direct air rotary.
- Samples are obtained when high pressure compressed air is injected down the annular space.
- Samples of the substrate from the reverse circulation method are often thought to be more correlative to the depth of the bit face and are favoured in mineral exploration.
A Special Rig That Works Amid Haiti’s Calamities
Components of Rotary Drilling System:
Actual mechanics of modern rigs are quite complicated while concept of rotary drilling-using a sharp, spinning drill bit to delve into rock is quite simple.
Basic Rotary Drilling system consists of 4 groups of components:-
- Prime movers are also known as power system of a rotary drilling rig as they provide power to the entire rig.
- When drill rigs were started, steam engines were used to provide power. Use of diesel and gas engines was common post World War II.
- Natural gas is also commonly used to generate electricity and power rig on site.
- Hoisting Equipment is made up of tools which are used to raise and lower when equipment go into or come out of the well.
- To support cables and pulleys, derrick is used which is also known as the most visible part of hoisting equipment.
- In deep wells, the combined weight of the drill pipe, drill bit and drill collars may be more than over thousands of pounds.
- Rotating Equipment is responsible for transferring power from the prime mover to drill bit.
- Swivel a freely rotating equipment carries the entire weight of drill string which is attached to hoisting equipment.
- Below the drill pipe is the drill collars which can be altered depending on down-hole condition experienced while drilling.
- Three important objectives of the circulating system are cooling and lubricating the drill bit, removing debris and cuttings and coating the walls of well with mud type cake.
- Drilling fluid is circulated down through well hole throughout the drilling process.
- Circulating system consists of drilling fluid pumps, compressors, speciality injectors and plumbing fixtures.
Addressing the Philippines’s energy crisis in lesser time with lesser manpower
Advantages of Rotary Drilling Rig:
- Lightweight modular design allows greater operational flexibility and makes the rigs easy to install and relocate.
- Drilling rigs are hydraulic with self- propelled and also equipped with computer operating systems.
- According to strata drilling, bits are configured, working in clay soil requires long drilling tube while short drilling tube is suitable for strata containing sand and cobble.
- Better penetration rate and high operational efficiency is achieved by the use of drilling muds which controls downhole pressure, stabilize the hole well, remove drill cuttings and lubricates the drilling bit.
- Rotary drilling rig is considered eco-friendly because of smaller vibrations and less-operating noise.
