Connecting to Illinois. Illinois has a long history of coal mining. The first discovery of coal in North America was in Illinois by Marquette and Joliet 4 In , they observed and recorded coal outcrops along the Illinois River. 4 The outcropped coal was mined in the s and used in blacksmithing and other domestic uses. 4 It took longer for underground mining to start, but by . The Illinois Basin is a Paleozoic depositional and structural basin in the United States, centered in and underlying most of the state of Illinois, and extending into southwestern Indiana and western basin is elongate, extending approximately miles northwest-southeast, and miles southwest-northeast.
Figure 5 is a map of inactive coal mines. Mining methods, depth of mining, and amount of subsidence varies across the state and within individual coalfields. Coal mining methods also influence the kind and amount of subsidence that can appear at the surface. back to table of contents Mining Methods Room and Pillar Mining. Among the duties of this office are: ensuring that active coal-mining operations are properly reclaimed, thereby assuring the restoration of lands affected by mining to productive uses; regulating repair to land and structures damaged as a result of mine subsidence resulting from underground coal mining; and inspecting all active coal-mining.
The plant of the Security Coal and Mining Co. is about three miles south of Duquoin, Ill., on the Illinois Central R. R. This is one of the mines operated by Rutledge & Taylor, a firm having offices in Chicago and St. Louis. The industry maintains, quite accurately, that strip mining is only a temporary use of the land, that all the land so mined in Illinois since the start of mining in the 's has affected less than one half of one percent of the state's land area while shopping centers, subdivisions.

Mining Board meetings are held to discuss topics related to the Coal Mining Act. It is the Board's responsibility to ensure the safety of the state coal industry and compliance with the Act.
Illinois is able to produce a constant supply of coal for industries of this vast area, not only because of the efficiency and enterprise of our mine labor, engineers, and operators in our rich and long established underground mines, but because of the development of strip mining which now accounts for per cent of the total coal production.

Underground agriculture is a way to reclaim abandoned tunnels in coal-mining systems, putting them to new, productive uses. Underground agriculture is also a way to help revive the economy of mining districts, transforming their basis from a limited-lifespan extraction industry to an unlimited-lifespan generative : Qingyi Zhao.

For much of the 19th and 20th centuries, the coal-mining industry thrived in the state's southern section, which sits atop a mile-long coal- and oil-rich geological formation called the Illinois Basin.
At its peak in the s, Illinois mines employed approximatelyworkers and produced million tons of coal : Dwyer Gunn.


A mineral is typically an inorganic substance that has a specific chemical compositionand crystal structure. The minerals are valuable in their pure form, but in the earth they aremixed with other, unwanted rocks and minerals. This mix of rock and minerals is usuallycarried away from the mine together, then later processed and refined to isolate the desiredmineral.
Mining is an industrial activity that removes rock from the Earth's crust and processes it tovaluable minerals for us to use. Some examples of substances that are mined include coa.gold, or iron ore. We need mineral resources to make many of the things we use in our dailylives, from toothpaste to buildings, computers to cars.
The two major categories of modern mining include surface mining and underground mininaIn surface mining, the ground is blasted so that ores near Earth’s surface can be removedand carried to refineries to extract the minerals. In underground mining, ores are removedfrom deep within the earth, Miners blast tunnels into the rock to reach the ore deposits

Title: Stoll family papers.
Volume of collection: 7.85 cubic feet.
Language of materials: Collection materials are in English and Spanish.
Collection summary: Papers and photographs of a family that ran Alaska Pacific Consolidated Mining Company and Independence Mine.
William M. Stoll (1926-1996) and Walter Clericus Stoll (1915-1978) were the sons of Walter W. Stoll, who was general manager of Alaska Pacific Mines from 1936-1943. The business later became Alaska Pacific Consolidated Mining Company (APCMCo.), which operated Independence Mine, one of the largest hard rock gold mines in south-central Alaska. Walter W. Stoll served as vice president of the company from 1943 until his death in 1949.
William “Bill” M. Stoll was a mining engineer who received degrees in mining and metallurgical engineering at the University of Washington and Stanford University. He worked for his father at APCMCo. in the late 1930s and early 1940s, after which he did fieldwork with the United States Geological Survey (USGS) on ore deposits. Bill returned to APCMCo. in 1946, became manager of Independence Mine until its close in 1951, and later served as APCMCo.’s director and president. In later years, he was involved with the tungsten carbide producer Kennametal, Inc. Bill Stoll was also the author of Hunting for Gold in Alaska’s Talkeetna Mountains, 1897-1951 (1997). He was married to Josette Ames Stoll and had two children, Laura and Paul.
Walter Clericus Stoll received B.S. in Mining Engineering from the University of Washington in 1939. After receiving his degree, Walter worked for the USGS, studying mineral and metal deposits in Idaho, Montana, and New Mexico. Beginning in the early 1950s, he became a mining consultant for numerous mining ventures in Spain and South America. In 1969, he formed his own company, Gold Resources, Inc., which focused on developing gold mining properties in Canada. Walter was known to his family as “Bobe.”

Chinese mining firm no longer operating-A A +A
Wednesday, December 4, 2013
THERE’S no case filed yet against a Chinese-owned mining company operating in Cagayan de Oro City’s upland village, the Mines and Geosciences Bureau (MGB) said Tuesday.
Engr. Daniel Belderol, officer-in-charge of the MGB’s mine management division in Northern Mindanao, said the mining firm has stopped its operations at present.
Belderol said that earlier this year, the MGB created a multi-sectoral task force to inspect the firm after the bureau received report about the mining operation.
In its inspection last February 14, 2013, the MGB, together with the Bureau of Immigration and Deportation (BID) and the Cagayan de Oro city police, discovered that the mining company is still operating.
MGB then issued a cease and desist order to stop the mining firm’s operation.
“As of now, we have no case against (the Chinese company) because their mining plant stopped operating upon the issuance of the cease and desist order from our office,” Belderol said.
“Nituman sila sa cease and desist order (They followed the cease and desist order),” said Belderol.
Belderol added that based on their recent inspections after the issuance of the order, they found out that the equipment in the area have not been used for a long time.
Edwin Dael, chief of the City Local Environment and Natural Resources Office (Clenro), confirmed the information from MGB that the Chinese-owned mining company stopped its mining operations.
Dael added his staff from Clenro visited the area for inspection and found out that the equipment of the said mining plant is already rusty.
“Their bulldozer is already rusting as you can see the scoop,” said Dael while showing Sun.Star Cagayan de Oro photos taken by his staff during an ocular inspection.
‘In good faith’
Rodante Felina, officer in-charge of MGB-Northern Mindanao’s mining environment and safety division, said the establishment of the mining plant was “in good faith.”
Felina said the mine processing plant was first established by Nahiliran and Monique small-scale mining.
“Nahiliran and Monique have small-scale mining permit that was issued by the previous administration,” said Felina.
Belderol added the Chinese company is more likely the eighth financier of the mine processing plant since Nihiliran and Monique.
However, Felina said their small-scale mining permit expired (this year) by the time the Chinese-owned company financed the mining plant.
“Upon expiration, they should have the mineral processing permit (MPP),” said Felina.
Felina added the MPP cannot be renewed following Executive Order 79 (EO 79), series of 2012, issued by President Benigno Aquino III and the Minahang Bayan Law.
“The Minahang Bayan Law limits mining only to gold, silver and chromite,” said Felina.
Belderol said that under the law, copper mining is prohibited, in which the Chinese-owned company was mining in the hinterland.
Application for mining
The cease and desist order stated that the company filed for a MPP to the MGB.
However, the application lacked the requirements like the environmental compliance certificate (ECC) and National Commission on Indigenous Peoples’ certificate of precondition, among others.
The order also stated that EMB has “… identified with clear and convincing evidence certain persons who are actively engaged in these illegal activities…”
“Further, all violators of this cease and desist order shall be charged appropriately for violations of Republic Act 7942 or the Philippine Mining Act, pertinent provisions of the Revised Penal Code and Environmental Laws…” the order read.
The order added that the violators will suffer arrest, imprisonment and confiscation of equipment used in the illegal activities. (Sun.Star Cagayan de Oro)

TSX- and NYSE-listed Asanko Gold generated record revenue of $91-million from selling 63 009 oz of gold in the third quarter, realising an average price of $1 443/oz.
The company produced a quarterly record 62 440 oz from its 50%-owned Asanko gold mine, in Ghana, and is on track to meet its yearly guidance of between 225 000 oz and 245 000 oz of gold.
The average gold grade achieved during the quarter was 1.4 g/t from 1.44-million tonnes milled.
“During the third quarter, we substantially completed the Cut 2 pushback at the Nkran pit of the mine, concluding a significant capital programme that allows the mine to focus on generating meaningful free cash flow.
“Increased free cash flow will strengthen the balance sheet at both the corporate and joint venture (JV) level,” said CEO Greg McCunn.
He added that, during the third quarter, the company received $10-million from its JV partner, JSE-listed Gold Fields, and expected to receive another $10-million on or before December 31, which will further strengthen the corporate balance sheet.

China implemented export controls on gallium and germanium on August 1st, two rare earth metals essential for semiconductor manufacturing. The restrictions are not a complete ban—China will require a license from the Chinese Ministry of Commerce with specified information on the recipient and purpose of use for exports.
Ex: AXT, a US manufacturer of these products in China, is looking to gain permission to continue exports. China’s Rare Earth Market China holds the world’s largest reserves of rare earth elements, with many of them necessary for semiconductor production. Roughly 44M tons of rare earth oxides (REO) ”lie dormant” in Chinese soil. The US is the second largest producer of REOs with a market share of 15.5%.


Harmony Gold Mining Company Ltd.
In South Africa, where electricity is still mostly coal generated, mining consumes approximately 15% of the electricity produced in the country, with gold mining alone responsible for almost half of this.
As the availability of gold ore is declining in South Africa  the exploration of mines is going deeper, pushing energy demand to an all-time high. So improving energy efficiency to reduce carbon emissions and operation costs is a pressing challenge for the sector.
Harmony Gold is a mining company that is aware of the urgent need to find alternative solutions that make both environmental and business sense. In its Kusasalethu mine, situated 75 km west of Johannesburg, for example, the company has attempted to do just that. Since 2009, Harmony has been investing in increasingly energy-efficient technologies to make operations at Kusasalethu more sustainable. For instance, it improved the efficiency of its air pumping systems, whose energy consumption, emissions and costs tend to increase with the depth of underground mining.
Cumulative investment in efficient technology has resulted in a significant reduction of carbon emissions right from the start. Between 2008 and 2012, 616,000 tonnes of CO2 were avoided at the mine. After investing approximately US$1.7 million in the new pumping systems, among other investments in energy efficient technology and maintenance, the mine saw its profits rise by 33% in just one year—also due to increased gold output and other contributing factors.
As Harmony Gold is showing, investing in energy efficiency is both an environmental necessity and a financially progressive decision in the mining sector.


Helicopter- and drone-based exploration
The availability of technology metals is a basic prerequisite for advancing digitalisation and enabling the turnaround in energy policy. The predicted demand for some metals in the coming decades exceeds the currently known deposits. To explore new mineral deposits, electromagnetic induction methods can be used that display the electrical conductivity distribution of the subsurface resolved in depth.
The Working Group for Applied Geophysics is pursuing a novel approach in which the electromagnetic induction field is recorded during the overflight of one or more high-voltage transmitters installed on the ground using highly sensitive magnetometers integrated in a helicopter or UAV (see figure). With this approach, the depth of exploration can be significantly increased compared to classic helicopter-based electromagnetic measurement methods and thus new raw material deposits can be explored.
The methodology is also promising for the exploration of deep groundwater deposits and geological structures in general.

Mine Subsidence - An Overview
In order to consider potential impacts of underground mining on overlying structures, water resources, and surface land, it is first necessary to have some understanding of the mechanics of mine subsidence.
Mine subsidence can be defined as movement of the ground surface as a result of readjustments of the overburden due to collapse or failure of underground mine workings. Surface subsidence features usually take the form of either sinkholes or troughs.
Sinkhole subsidence is common in areas overlying shallow room-and-pillar mines. Sinkholes occur from the collapse of the mine roof into a mine opening, resulting in caving of the overlying strata and an abrupt depression in the ground surface. The majority of sinkholes usually develop where the amount of cover (vertical distance between the coal seam and the surface) is less than 50 feet. This type of subsidence is generally localized in extent, affecting a relatively small area on the overlying surface. However, structures and surface features affected by sinkhole subsidence tend to experience extensive and costly damages, sometimes in a dramatic fashion. Sinkhole subsidence has been responsible for extensive damage to numerous homes and property throughout the years.
Sinkholes are typically associated with abandoned mine workings, since most active underground mines operate at depths sufficient to preclude the development of sinkhole subsidence. In accordance with the current regulations, the Department will not authorize underground mining beneath structures where the depth of overburden is less than 100 feet (30.5 m), unless the subsidence control plan demonstrates that proposed mine workings will be stable and that overlying structures will not suffer irreparable damage.
Subsidence troughs induced by room-and-pillar mining can occur over active or abandoned mines. The resultant surface impacts and damages can be similar, however the mechanisms that trigger the subsidence are dramatically different. In abandoned mines, troughs usually occur when the overburden sags downward due to the failure of remnant mine pillars, or by punching of the pillars into a soft mine floor or roof. It is difficult, if not impossible, to predict if or when failure in an abandoned mine might occur, since abandoned mines may collapse many decades after the mining is completed, if the mine workings were not designed to provide long-term support.

THE INTRIGUING FUNCTIONALITY OF BUNKER CONVEYORS
In the modern world of industry and manufacturing, conveyor belts play a crucial role in efficiently and effectively moving materials from one location to another. One particularly fascinating type of conveyor is the bunker conveyor, which is an essential link in numerous industries, ranging from agriculture to mining and everything in between. In this blog, we dive deeper into the functionality of bunker conveyors and how they contribute to different industries.
What is a bunker conveyor belt?
A bunker conveyor belt, also known as a hopper conveyor, is a type of conveyor specifically designed to store and gradually feed materials for further processing or transport. The essence of a bunker conveyor is the funnel-shaped structure at the beginning, the "bunker", in which materials can be temporarily stored before being fed to the main conveyor. This temporary storage makes it possible to maintain a constant and controlled supply of materials, even if the supply source is irregular.
Applications of bunker conveyor belts
Building and construction: In the construction industry, bunker conveyor belts are often used to transport materials such as sand, gravel and rubble from trucks to building sites. The bunker function ensures a steady flow of materials, so the construction process is not delayed by irregular supply.
Agriculture: Bunker conveyor belts are invaluable in the agricultural sector, where they are used to move crops such as grain and potatoes from the field to storage facilities. The funnel-shaped bunker ensures that harvested crops are evenly distributed on the conveyor, preventing damage and increasing efficiency.
Mining: In the mining industry, bunker conveyor belts are used to transport ores and minerals from mine sites to processing facilities. The storage function allows miners to collect large quantities of material before it is processed, optimising the process and enabling a continuous flow of raw materials.
Advantages of bunker conveyor belts
Continuous feeding: The funnel-shaped bunker allows continuous and even feeding of materials, even when the source of material is irregular. This minimises downtime and increases the efficiency of operational processes.
Protection of materials: Storing materials in the bunker ensures that they are not directly exposed to weather conditions or possible damage during transport. This helps maintain the quality and integrity of materials.
Efficiency: Bunker conveyor belts reduce the need for manual intervention to feed materials, which minimises human error and increases overall efficiency.
Processing optimisation: In industries such as agriculture and mining, the gradual feeding of bunker conveyor belts allows better control over the further processing process, improving the quality of the final product.
VERSATILITY OF BUNKER CONVEYOR beltS
Bunker conveyor belts play a vital role in various industries due to their unique ability to store and gradually feed materials for further processing or transportation. This functionality results in continuous feeding, protection of materials, improved efficiency and optimisation of handling processes. Whether in construction, agriculture, mining or other sectors, bunker conveyors remain an indispensable link in the chain of industrial activities, enabling companies to keep running smoothly and deliver high-quality products.
We supply conveyors based on quality, robustness and durability. You can also come to us for advice, for example on the correct assembly and loading of conveyor belts, for optimal running.

With the South African government trying to lay groundwork in preparing the country for the Fourth Industrial Revolution (4IR), another company has begun with introducing much-needed technology for its employees.
Said company is Anglo-American which announced earlier this week that it has introduced its second underground WiFi setup, which is said to improve working conditions for hundreds of its underground miners in Mpumalanga, Goedehoop Colliery coal mining operations. The WiFi will enable two-way communications between miners working underground and staff on the surface, the company says.
According to Anglo-American, Zibulo Colliery was the first South African mine to introduce this technology in 2016, with Goedehoop Colliery becoming the second operation to introduce the safe wireless communication infrastructure and smartphones at its 4 million tonne per annum Simunye Shaft.
“We’re working in an environment where safety and productivity are paramount. The introduction of underground WiFi is a game-changer. It allows our miners to communicate more easily, thereby making mines more productive. The main benefit is that breakdowns can be reported and resolved faster, in some cases, by contacting equipment manufactures on the spot,” said Anglo-American’s, Edgar Simfukwe.
Furthermore Anglo-American states that traditionally coal mines used fixed underground telephones which frequently required a long walk or drive to reach and required employees to often return to the surface to get a message to a college, report a problem or access critical information.
“Up to 750 people work in an area of 20 square kilometers, so it’s important that we know where each of them are if an underground emergency occurs. Should an evacuation occur, we are able to determine from the control room whether anyone has been left behind, exactly who they are and their last known location,” added Simfukwe.
The mining company adds that with the new WiFi and smartphones, miners can communicate instantly via voice calls or text messages to and from the surface, and from one underground section to another. Explaining that apart from resolving communication challenges, the WiFi network also tracks key equipment through communication tags.
“Installing WiFi underground is significantly more difficult than above ground. There are no cell phone towers underground, and signals are weakened and distorted by uneven surfaces, earthen walls and other obstacles in tunnels of different sizes. However the benefits rapidly repay the initial R10 million investment, concluded Simfukwe.

The Yavu gold-silver project is located in Yavu District, Sivas Province, Turkey (Figure 1). This project area is covered by three mining licenses owned by OGM Mineral Corporation (Figure 2). The project is approximately 450 kilometres east of Ankara, the capital city of Turkey, and 50 kilometres west of Sivas, one of the most important mineral provinces of Turkey. Yavu gold-silver mineralization has been described for the first time.
The host rocks are formed the schist and gneiss of the Akdağmadeni metamorphics and volcanic series. Ore minerals observed include gold, silver, chalcopyrite, pyrite, arsenopyrite, malachite, azurite. Precious metals such as gold and silver enrichments are located along the fractures in metamorphic rocks and volcanic series in the quartz veins and veinlets that cut the metamorphic rocks as disseminated, stockwork and fault crack filling. The host rock alteration is composed of kaolinization and strong silicification. OGM Mineral Company initially identified three primary orogenic deposit zones in target zones within a broad 6.2 by 6.0 kilometre area as a conclusion of gold-silver general geochemistry. The three target zones are Yavu, Killik and Kücükakören area are named. However, the projects are collectively named Yavu Gold-Silver Project. The surface expression of the veins and silicified zones range from 0.5 to over 85 meters in thickness, and 50 to 200 meters in length. The host rocks included some textural characteristics of the orogenic-mesothermal and low sulphidation epithermal type deposit. In conclusion of some geochemical analysis, all host rocks show grades of gold between 0.37 ppm and 11.3 ppm@3m., and silver grades between 0.05 ppm and 117.5 ppm @5m. The system has characteristics of orogenic-mesothermal formation and low sulphidation epithermal processes for the genesis of the gold-silver and base metal mineralization.
