2012-8-30 · 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
The term "continuous" as applied to development machines has been one of the biggest misnomers used for mining equipment because, on development, they are usually anything but continuously cutting. The main delays mostly occur while roof support is installed and often waiting for shuttle cars to return from their discharge point for reloading.
