Mining into such abandoned voids poses a great safety risk to personnel, equipment, and production from inundation or toxic/explosive gas release. Often, surface or underground drilling is employed to detect the mine void and evaluate the hazards, sometimes with disastrous results.
The highwall mining machine is positioned on the pit floor or on a bench beside the highwall in front of the coal seam. A cutterhead attached to a string of push beams is thrust into the seam. The coal is mined by the shearing action of the cutterhead that is raised and lowered to dig out the entire height of the coal seam.
® Plow Systems for Low Seam Coal. Plowing is the preferred longwall mining technique for seams below 1.8 m (71 in), and under specific geological conditions, even below 2.3 m (90 in). Today, is the market leader in the field of fully integrated and automated plow systems.

In addition to our underground mining transport systems, Powertrans manufactures truck and powered and unpowered trailer systems for use in surface mining. Our PowersparesTM division supplies a range of spare parts for the heavy-duty haulage industry.
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 a pit, and theHistory · Methods of extraction · Modern mining · Safety
It is a genuinely disruptive technology for all other mining methods and is poised to fundamentally change the nature of the mining coal. PBE is a remote controlled UG mining technology that utilises military standard inertial navigation & guidance systems integrated with advanced positioning and situational control systems.
Underground Mining for Meeting Strategic approach for underground coal mining in India The Working Group on Coal and Lignite have worked out two scenarios for coal demand for XII Plan period after consultation with the major consuming sectors, Under Scenario-I (Consumersâ perspective demand), the demand works out to 1203.88 MT
Abstract The coal mining industry needs to detect coal seam boundaries and hazards such as abandoned mines, water filled cavities, and old steel drill casings ahead of the mining
The main goal of the work was to determine whether a radar-based system could be used to detect coal-rock interfaces in order to establish a suitable mining horizon within the coal seam.
Mining is the extraction of valuable minerals or other geological materials from the earth, usually from an orebody, 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.History·

Coal mining is the process of extracting coal from the ground. Sensors detect how much coal remains in the seam while robotic controls enhance efficiency. Longwall systems allow a 60-to-100 percent coal recovery rate when surrounding geology allows their use. Longwall mining is a form of underground coal mining where a long wall of coal
