Abstract: A power supply system for a drum-cutter mining machine utilized in longwall mining operations. Three-phase electrical power is supplied to a rectifier circuit positioned remote from the mining machine to rectify the three-phase electrical power. Rectified electrical power is supplied to the mining machine through cables, whereat the electrical power is inverted by inverters. Power transistors are coupled between the inverters and the respective motors of the mining machine. Positioning the rectifier remote from the mining machine allows the body of the mining machine to be of reduced dimensions.

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.

Abstract: A two-way communication system for transmitting command signals to and receiving operating data from a winning machine utilized in underground mining operations. The system includes a send-receive facility positioned remote from the winning machine for transmitting command information to the winning machine. A receiving means is positioned at the winning machine for receiving signals sent by the send-receive facility, and a transmitting means is positioned at the winning machine for transmitting signals corresponding to operating data of the winning machine. The send-receive facility receives the information transmitted by the transmitting means, and a separable memory is separably attached to the send-receive facility for storing such operating data and the command information. Because the memory is separable, the memory may be removed to allow the data contained therein to be analyzed at a remote location.
