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 per­

Continuous Mining Coal Leader

Continuous miners operate a room and pillar mining system. A series of 18 to 20 foot wide rooms are driven in the coalbed with pillars or columns of coal left standing to help support the roof. Roof bolts, typically four to six feet long steel bolts, are inserted into holes bored into the roof to bind the strata together support the roof.
