Abstract
One phase of Bureau of Mines research deals with reduction of primary respirable dust generated by bit cutting action at a coal seam face. This paper presents a summary of coal cutting technology addressing this problem. All aspects of the cutting system affecting miner health and safety are discussed. Cutting design concepts are considered that minimize dust generation, energy used, and ignitions, while maintaining production. With present equipment, an operator can maintain production and minimize dust energy and ignitions by cutting at maximum depth (maximum sumping or advance rate) at all times, at minimum revolutions per minute with fewest possible bits, and with lowest possible included bit tip angle, i.e., minimum bit wear.
