Coal mining Wikipedia

Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a 'pit', and

Mining Wikipedia

Mining is the extraction of valuable minerals or other geological materials from the Earth, usually from an ore body, lode, vein, seam, reef or placer deposit.These deposits form a mineralized package that is of economic interest to the miner. Ores recovered by mining include metals, coal, oil shale, gemstones, limestone, chalk, dimension stone, rock salt, potash, gravel, and clay.

Equipment You'll Find at a Typical Surface Mine

Draglines, a type of specialized excavation equipment, operate by casting a heavy cable-hung bucket outward from a crane-like boom and dragging the bucket toward itself to remove large amounts of overburden, load ore, and manage stockpiles. Draglines can be equipped with buckets of specific design and weight to match the materials being mined.

MINING EQUIPMENT SELECTION FOR A TYPICAL OPENCAST MINE

decisions concerning the selection of mining equipment for opencast coal mines in the Witbank Area of South Africa with the object to optimize initial capital outlay and to minimize operating costs. For the purpose of this study a typical geological section of the area, consisting of soft overburden or topsoil, underlaid by hard sandstone and siitstone overburden and the five main coal seams

Equipment Selection for Surface Mining: A Review

A surface mine contains pits with mineral endowed rock (or ore). We extract ore that lies within the upper layer of the earth, from surface mines (Fricke, 2006) . This ore can include metals such as iron, copper, coal and gold. There are several methods of surface mining, including open-pit, stripping, dredging and mountain-top removal. This paper focuses on open-pit surface mining, which

Rock dusters are pressurized pieces of equipment that coal miners use to spray inert mineral dust over highly flammable coal dust. The inert dust helps prevent accidental fires and explosions. Shuttle Cars and Scoops. Coalminers use electric-powered shuttle cars to transport coal from the coal bed to safer points in the mine. From there, miners can use standard scoops, or haulage vehicles, to

Appendix E: Coal Mining and Processing Methods Coal

In both conventional and continuous methods, coal is loaded onto coal transport vehicles and then dumped onto a panel-belt conveyor for transport out of the mine. Once the coal has been cut, the strata above the excavated coal seam are supported by roof bolts. Under favorable conditions, the production from a continuous miner section can exceed 800,000 tons per year per continuous miner.

Underground Mining Transportation Systems

namely the movement of ore/coal, persons, materials and equipment. Ore/coal transport has either been by locomotive-hauled mine cars, belt conveyors or rubber-tired trucks. The transport of persons, materials and equipment has either been by rail-mounted track systems or trackless systems/movable vehicles. Each system described above is still widely popular for those various specific reasons

Surface Mining Methods and Equipment

Highwall mining is a coal mining method for recovery of outcropped coal by mechanical excavation without removal of overburden. A continuous miner with single or multiple augers/cutting heads is operated underground and controlled remotely by crew located outside. Augering can be regarded as a supplementary method for open cast mining in cases when coal seams in the highwall would
