Deep Cutting Continuous Miner Effect of Drum Rotational Speed and Depth of Cut on Airborne Respirable Dust and Specific Energy.
NTIS: PB 274 345 Available for Reference At Bureau Libraries :288 pages
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.
