The results of a Bureau of Mines laboratory investigation of coal cutting mechanics and noise is presented. Some basic theoretical aspects of coal cutting mechanics and noise generation are discussed, and the results of the laboratory experiments are used to formulate analytical models of the coal cutting forces and noise. It is concluded that by using deeper depths of cut, slower cutting speeds, and more efficient cutting tools, it is possible to reduce the level of coal cutting noise as well as provide benefits to other important areas of underground health and safety. In addition to these basic operational parameters, fundamental structural design criteria for reduced-noise coal mining machine cutting heads are also presented.
