Basic Mining Process/Terminology
Adjoining intake and return airways are separated by the coal pillars or by installing stoppings (most commonly in the form of a wall of some kind) in any interconnecting roadways to prevent air short-circuiting between the roadways. Sometime doors are used in place of stoppings to allow passage of equipment or personnel where required.
