Underground Mining. Underground mining has the potential for tunnel collapses and land subsidence (Betournay, 2011). It involves large-scale movements of waste rock and vegetation, similar to open pit mining. Additionally, like most traditional forms of mining, underground mining can release toxic compounds into the air and water.
Mining at the depth below 1000 m requires automated single-operator mining machines equipped with modern work tools and air-conditioned operator cabins conforming to the current standards for structures protecting the operator against rock slides in underground excavations.

Longwall mining replaces the historical "room-and-pillar method", whereby underground "rooms" of coal are manually extracted and pillars are left to support the roof so miners can work safely. In mining regions deeper than 1,000 feet (300 meters), the room-and-pillar method becomes highly uneconomical because the size of pillars required to ...
The underground environment is constantly changing as a mine develops, and those working at height need to be aware of this constantly changing three-dimensional situation.
