Mine Power & Drainage System

Mine Power & Drainage System

when using a shearer in a longwall mining operation a temporary mechanical hydraulic roof support system is needed to stabilize the mine's roof. the roof ,room and pillar mining,room and pillar (variant of breast stoping), is a mining system in which the mined material is extracted across a horizontal plane, creating horizontal arrays of rooms and pillars. to do this, 'rooms' of ore are dug out while 'pillars' of untouched material are left to support the roof overburden. next, mine layout should be determined, as factors like ventilation, electrical
