Abstract
A shoveling apparatus including a low profile vehicle, a boom assembly, and a shovel assembly for use in underground mining operations, and particularly useful in clearing coal and rock debris from a belt line corridor. The low profile vehicle includes an advanceable support that supports the boom assembly and laterally advances the boom assembly from the cab portion of the vehicle. The boom assembly includes a support structure, a rotary actuator and a linear actuator, to control lateral and vertical rotation of the support structure (and thus the shovel assembly) with respect to a ground surface. The shovel assembly includes a rotary actuator and a shovel, and in some embodiments a tilting mechanism, to control the lateral and in some cases vertical, rotation of the shovel with respect to the boom assembly.
