Results are presented for two major areas of research that address solutions to problems associated with health and safety aspects of rotary-drum mining machines. The results presented describe proof- of-concept testing for the U.S. Bureau of Mines' new constant depth linear cutting (cdlc) concept and use of computer analysis for cutter system modeling (csm) of rotary cutting drums. The cdlc concept uses a triangular drum on an eccentric arm which operates at low rpm. Results of proof-of-concept tests show a reduction in respirable dust of greater than 90 pct with an increase in product size of 50 pct for the minus 1/4-in mesh with no loss of production when a 10-rpm linear drum is compared with a 50-rpm rotary drum. An exclusive license has been granted to a mining equipment manufacturer on four government-held patents to accelerate transfer of the technology to the coal mining industry. The csm's have been developed for computer analysis of the cutting systems on continuous and longwall miners. Use of these csm's will reduce the operator's cut-and-try time needed to identify minimum dust generation for maximum production.
