A surface mining system for removing material from a mining face generally includes a conveyor extending substantially parallel to the mining face, a miner supported by and moveable along the conveyor, and a conveyor translation device associated with the conveyor and operable to move the conveyor and the miner toward the mining face. A method for advancing a surface mining longwall system generally includes moving the longwall shearer along a face conveyor, operating load translation devices to move the face conveyor and the longwall shearer toward the mining face, resetting a first group of load translation devices, and then resetting a second group of load translation devices. A load translation device generally includes an actuator, a ground drilling device coupled to and moveable with a portion of the actuator, and a frame coupled to and moveable with another portion of the actuator.

Advancing longwall system for surface mining

A side shifting conveyor is provided for a surface mining operation. The conveyor generally includes conveyor sections and conveyor translation devices. Each conveyor translation device includes a drive operable to move the associated at least one conveyor section in a direction substantially perpendicular to the conveying direction. The conveyor further includes a controller operatively coupled to each drive for controlling operation of the drive and coordinating movement of the conveyor sections. A method for moving a conveyor in a surface mine generally includes sensing that a surface miner operable to deposit material onto the conveyor sections has moved beyond one of the conveyor sections, fixing a position relative to the surface mine of a conveyor translation device associated with one of the conveyor sections, and operating the conveyor translation device to move one of the conveyor sections in a direction substantially perpendicular to the conveying direction.

Conveyor system for continuous surface mining

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.
