Abstract
A drum-cutter mining machine for longwall mining operations which is adaptable for use upon longwall conveyor systems having rack structures positioned on either, or both, sides thereof. Drive motors are removably supported in a capstan housing of the mining machine, and positioned such that rotating shafts thereof extend toward either or both sides of the mining machine. Drive wheels coupled to the rotating shafts through reduction gears engage with the rack structures to allow translation of the machine therealong. When the mining machine is to be utilized on a longwall conveyor system having an alternate rack structure position, the drive motors may be removed, reoriented, reinserted into the capstan housing, and the drive wheels may be repositioned to allow operation of the mining machine.
