Surface mining, including strip mining, open-pit mining and mountaintop removal mining, is a broad category of mining in which soil and rock overlying the mineral deposit (the overburden) are removed, in contrast to underground mining, in which the overlying rock is left in place, and the mineral removed through shafts or tunnels.
A continuous highwall mining system (CHM) was used to develop the roadways for a proposed punch longwall operation at Kenmare 2. The aim of the research project was to monitor, evaluate and model the roadway performance during the initial roadway driveage and subsequent widening using CHM.
Highwall miner A highwall mining system consists of a remotely controlled continuous miner which extracts coal and conveys it via augers, belt or chain conveyors to the outside. The cut is typically a rectangular, horizontal cut from a highwall bench, reaching depths of several hundred feet or deeper.
