The underground mining methods we use include room and pillar, narrow vein stoping and large-scale mechanised mining. Room and pillar mining is a style of mining where tunnels are driven in a chess board pattern with massive square pillars between them which are gradually cut away as the work proceeds. We use this for mining coal.
Dec 27, 2018· Subterranean coal miners use the machines to scrape coal from coal beds. In particularly dangerous situations, workers control robotic continuous miners remotely. Longwall Miners. In contrast to continuous miners, longwall miners remove large, rectangular sections of coal instead of scraping coal from a bed bit-by-bit.

Jan 14, 2019· The yearly average in coal mining decreased to 30 fatalities from 2001-2005, though 60 to 70 miners still die each year in the U.S. coal and non-coal mining industry. The most common accidents occurring in the mining industry are the result of poisonous or explosive gases or mishaps relating to the use of explosives for blasting operations.
Extraction by longwall mining is an almost continuous operation involving the use of self-advancing hydraulic roof supports, a sophisticated coal-shearing machine, and an armored conveyor paralleling the coal face. Working under the movable roof supports, the shearing machine rides on the conveyor as it cuts and spills coal onto the conveyor for
Continuous mining is the most prevalent form of underground mining, accounting for 56% of total underground production. In continuous mining, a machine known as a continuous miner cuts the coal from the mining face, obviating the need for drilling and blasting.
