Abstract
A surface mining system removes material from a surface mining block that has a substantially vertical and laterally extending mining face. The surface mining system generally includes a miner moveable in a lateral direction along the mining face, a face conveyor extending along the mining face, and conveyor translation devices associated with the face conveyor and operable to move the face conveyor toward the mining face as material is removed. The miner includes a rotating cutting member mounted to an end of a vertically ranging cutting arm and operable to remove material from the mining block. The face conveyor includes a discharge portion and is operable to convey material removed from the mining block toward the discharge portion. Each conveyor translation device includes a secured configuration substantially fixed with respect to the mining face and an unsecured configuration moveable with respect to the mining face.
