Hydraulic mining consists of coal erosion by powerful jets of water from hydraulic monitors operated by remote control. The broken coal is crushed and mixed with water and then transported from the face to the surface using gravity whenever possible. This is a simple, safe and productive method. It will easily satisfy North American productivity standards if the structural features and coal properties are favourable for water jet cutting technology (Kaiser Resources Ltd., hydraulic mine).
