Abstract
Longwall mining in lower seam heights may necessitate the use of single drum shearers to overcome size constraints associated with standard double-drum shearers. In an effort to evaluate the unique dust control problems associated with this type of mining, the U.S. Bureau of Mines conducted dust surveys on two multi-machine longwall operations. Sampling was conducted to quantify major sources of respirable dust and to identify potential solutions to overcome problem areas. Sampling results indicate that the cutting sequences utilized on multi-machine faces may have to be designed to minimize dust exposure, as opposed to optimizing productivity or operational requirements.
