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
