A special, deep-cutting continuous miner was built to study the effects of rotational speed and depth of cut on airborne respirable dust. After preliminary tests indicated and verified that deep- cutting, low-rotational speed reduces airborne respirable dust, a series of underground tests were performed. Additional data were obtained on specific energy, coal spacing, and noise.
