Continuous Mining: A Pilot Study of The Role of Visual

The Continuous Mining Process Typically, to begin a room, the continuous miner engages in cutting (removal) a 3 m (9.8 ft) wide sec-hon of coal to a depth determined to be safe based on local geologic conditions and mining regula­ tions-on average up to 6.1 m. Deeper cuts can be made (called extended-cut mining) with special per­get price

Room and pillar mining Wikipedia

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.Calculating the size, shape, and position of pillars is a complicated procedure, and is an area ofget price
