An effort was made to simulate with 21 different coals the grinding action which occurs when coal is trapped between the cutter head of a continuous miner and the coal face. The purpose was to evaluate the dust produced with different coals. Experiments in a Hardgrove grindability machine showed a significant effect of coal rank on the Hardgrove grindability index; the effect of volatile matter was also significant. The rather complex methods of analysis used are given in detail. (LTN)
