Underground mining operations around the world pose similar risks to worker safety and health. Though different techniques are used to extract base metals, precious metals, nonmetallic minerals, diamonds and coal, the hazards do not differ that much. The deeper the mine, however, the greater the risk. Safety Challenges in Underground Mines.
Underground mining for coal is conducted by either room and pillar mining or longwall mining. In room and pillar mining, approximately 50 percent of the coal is removed, using a continuous miner, from areas known as rooms. The rest of the coal is left in place in the .
Underground coal mining impacts. Although seen as less destructive than strip mining, underground mining still causes widespread damage to the environment. Subsidence. Collapse of earth into underground mines, or subsidence, is a serious problem.
Longwall Mining — One of three major underground coal mining methods currently in use.

Outside the USSR, underground mining is widespread in Canada, the United States, Mexico, Chile, Sweden, France, the Federal Republic of Germany, Rhodesia, Zambia, the Republic of South Africa, and Australia. Many underground mines of comparatively low output are located in .
Industry Experts. Working directly with coal is literally dirty work. Additionally, it has inherent dangers from gases like methane, and explosions can occur when falling rocks cause sparks. We design our coal mine networks with these hazards in mind, ensuring all applicable equipment is intrinsically safe (IS),...
In underground coal mining, coal dust is produced at the face, at conveyors, at transfer points, and by the normal movement of machines. Coarse coal dust settles rapidly while finer coal particles remain airborne. Fine dust can be moved relatively long distances by ventilating air before settling.
MineVIZ™ Underground Coal The purpose of the 5DT Underground Coal Mining Visualizer (MineVIZ™ – UG Coal) is to enable users to visualize the processes and activities in an underground coal mining section.
Other underground coal mines are laid out in a checkerboard of rooms and pillars (Fig. 2), and the mining operation involves cyclical, step by step mining sequences. The rooms are the empty areas from which coal has been mined, and the pillars are blocks of coal (generally 40 to 80 feet on a .
