CONTINUOUS MINER – Mining Science and Technology

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.

The continuous miner will continue advancing forward with the sump-shear cycles until there is a reason to stop the advance. In U.S. coal mines, the forward advance is limited by a few factors: the need to ventilate the face to maintain safe methane levels and the need to install roof bolts to prevent roof failure.
