Influence of Continuous Miner Bit Sharpness and Coal Lithotype Composition on Coal Breakage: Examples from Kentucky Mines

摘要

This pilot study addresses the influence of coal lithotype, continuous miner bit sharpness, and coal hardness on particle sizing and liberation characteristics. The interface of the 'job end' of the traditional continuous mining machine and the given geologic conditions at the job site; and their combined influence on particle sizing and liberation is investigated.
