Coal mining - Coal mining - Underground mining In underground coal mining, the working environment is completely enclosed by the geologic medium, which consists of the coal seam and the overlying and underlying strata. Access to the coal seam is gained by suitable openings from the surface, and a network of roadways driven in the seam then facilitates the installation of service facilities ...

Longwall mining is a highly productive underground coal mining technique. Longwall mining machines consist of multiple coal shearers mounted on a series of self-advancing hydraulic ceiling supports. The entire process is mechanized. Longwall mining machines are about 800 feet 240 meters in width and 5 to 10 feet 1.5 to 3 meters tall.

Moving underground coal mining equipment from one section to another can be time consuming and costly. Traditionally, moving a large electrically powered piece of equipment, such as a continuous miner, feeder-breaker or a roofbolter, required the power center to move along with the equipment.
An underground coal mine is a mine at which coal is produced by tunneling into the earth to the coalbed, which is then mined with underground mining equipment such as cutting machines and continuous, longwall, and shortwall mining machines, and transported to the surface. Underground coal mines are categorized as active if any one of the ...

Underground mining is one of the most dangerous jobs in the world. Underground explosions and toxic gases are the immediate threats that miners would face. In an underground mining site, the methane released from the rocks and the coal dusts generated during the mining process can both lead to
Mine Machines, Coal Cutting In the early days of using coal, loose coal would be gathered by hand where coal seams reach the Earths surface outcrop. Hand tools such as picks were used to get the coal. As seams were mined underground, sharpened hand tools were the standard equipment and continued to be used in small mines until the 1950s.
The two major schools of coal mining are surface mining and underground mining. To qualify for surface mining, the coal seam must lie within 60 metres of the surface. The miners job is to remove all of the overburden the cubic tons of rock, soil and trees above the coal seam -and expose the coal layer for extraction.
