Abstract
A major research effort by the Bureau's Coal Cutting Technology Group at Twin Cities Research Center has been directed to reducing respirable dust generated by the cutting action of bits on a rotating-drum-type mining machine. The research being conducted is specifically oriented to long-range solution of dust generation during cutting by optimizing all facets of the cutting system and the supporting mining machine that affect the cutting system. The end result of this effort will be a cutting system model in a computer program format for operators to use in identifying the effects on respirable dust of changes in the cutting system. Many factors are involved in a full analysis of the cutting system, but one of the most significant, and perhaps the most difficult to mathematically define, is bit wear. This paper provides a brief referenced review of previous research. It also discusses current fundamental research on bit wear and in situ field testing to support the cutting system model. An alternative cutting system which would reduce dust generation by engineering design is briefly described.
