Normally, one hour of each shift is spent moving the continuous mining machine from place to place in order to accomplish the roof bolting (required by federal regulations). It appeared that a system integrating roof bolting as part of the basic mining cycle would save at least part of that hour each shift. To that end, the US Bureau of Mines requested proposals for a Miner/Bolter system that could mine an average of 750 tons per shift in 5-foot seam heights. The Jeffrey Mining Machinery Division of Dresser Industries, Inc., was awarded one of five concept studies of such a system. The study resulted in concept definition for a Bolter Transfer Machine (BTM), to follow immediately behind the continuous mining machine, providing automatic installation of roof bolts across the width of the entry. The concept included a continuous mining machine, modified for single-pass mining, and operated by radio remote control from an operator's position behind the automated roof bolters. The continuous mining machine and the BTM comprised a Miner/ Bolter system that could advance continuously without stopping for place change. The program progressed through detail design, laboratory test of one bolter module assembly, drilling and installing a series of 100 roof bolts, and fabrication and checkout of the BTM assembly. Assembly of the BTM was nearly complete, and checkout was started, when work was stopped because of inadequate funding. A very restricted DOE budget resulted in stopping the project and subsequent dismantling of the machine. All usable components, including the four bolter modules, were delivered to the Spokane Mining Research Center of the US Bureau of Mines for future experimentation.
