How a Continuous Miner Works Underground

2021-4-28  Extracting the pillar blocks using continuous miners comes in handy, especially when the longwall mining method is impossible. The process entails splitting pillars and working with smaller sections called lifts driven with the miner. These remain intact at the roof as coal is extracted from them.

Shortwall Mining Introduction underground COAL

An installation roadway was driven as for a normal longwall, but only supports were installed. A continuous miner was then utilised to cut 3.5m wide open ended lifts off the face, with shuttle cars being used to transport coal along and off the face to the maingate belt in lieu of an AFC.

Modern Longwall Mining Coal Age

2012-9-14  Each continuous miner advances 300 ft in the same entry. The operators cut coal, dump it on the ground and bolt as they advance. Behind the continuous miner, loaders gather the coal and fill the shuttle cars. The continuous miners cut coal independent of shuttle car availability. Bailey is testing the new TON MB610 continuous miners.

Longwall Mining an overview ScienceDirect Topics

longwall mining Mining. a mining method in which very long rectangular blocks of coal are defined during the development stage of the mine and then extracted in a single continuous operation by an automated cutting head moving parallel to the coal face.When the coal is cut, the working area is protected by a movable, powered roof support system. As the face progresses, the immediate roof above
