Coal mining - Underground mining Britannica

Coal haulage, the transport of mined coal from working faces to the surface, is a major factor in underground-mine efficiency. It can be considered in three stages: face or section haulage, which transfers the coal from the active working faces; intermediate or panel haulage, which transfers the coal onto the primary or main haulage; and the main haulage system, which removes the coal from the mine.

8 Methods For Protecting Coal Miners

Exhaust fans are commonly used to ventilate underground coal mines. Positive-pressure fans are used infrequently-usually where the mine is close to the surface and there is leakage to the surface through the air intakes. The volume of air flow through an underground mine is a function of the fan capacity and the "resistance" of the mine ventilation configuration WcAteer 19811.
