serves from a surface mine when removal of overburden with sur- face mining equipment becomes uneconomical. Auger and con- tinuous miner head machines are the two major types of equip- ment used in U. S. highwall mining. The auger type machines use a horizontal auger to literally drill coal from under the highwall in a series of parallel holes.

Highwall mining is an adaptation of auger mining. Instead of an auger hole, an entry into the coal seam is made by a continuous miner, remotely operated from a cabin at the surface. The cut coal is transported by conveyors behind the miner to the outside. Using a television camera, the operator can see and control the miner's progress.
