Coal mining

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 ...

The extracted gas can be diffused into the ventilated mine workings or transported by a methane drainage network to the surface for utilisation or controlled exhaustion to the open atmosphere. The diameter of surface holes is 150 to 300 mm, which depends on working seam depth, gas and mining conditions as well as the source of gas transportation (suction or free flow - buoyancy effect).
