SYSTEMS Mining Science and Technology

HOMOTROPAL SYSTEM. In particularly dusty mines, the amount of dust in the mine atmosphere can be reduced by directing the air to flow in the same direction that the coal is being transported along the longwall face. This system is known as homotropal ventilation. The advantages of this system are: The intake air at the face is cleaner

Longwall mining SourceWatch

Longwall mining is a form of underground coal mining where a long wall of coal is mined in a single slice (typically 1-2 m thick). The longwall "panel" (the block of coal that is being mined) is typically 3-4 km long and 250-400 m wide. Longwall mining produced 176 million tons of coal in 2007, about 15 percent of total U.S. production.
