Abstract
Research results by the U.S. Bureau of Mines are presented for a major area of effort addressing a long-term solution to problems associated with health and safety aspects of rotary drum mining machines. Proof-of-concept testing for the Bureau's constant depth linear cutting concept is described. The concept uses a triangular drum, mounted on an eccentric arm, cutting to a free face at low rpm. Preliminary comparative test results, for synthetic coal, between the linear cutting concept and a standard rotary drum, show the linear cutting concept reduces entrained respirable dust by more than 95 pct, reduces -1/4-in-mesh product by more than 50 pct, and reduces horsepower by approximately 70 pct. These results are used to calculate the power requirements for a new, all-diesel mining system to improve miner health and safety and productivity while reducing costs.
