Abstract
Complying with reduced dust standards (that is, less than 2.0 Mg/m3) owing to quartz levels that exceed 5% is presently a critical problem for many continuous mining sections. Results are presented of research that was performed to determine the factors causing high levels of respirable quartz dust and to identify the major contributors to operator exposure. The significant sources of quartz dust are the drilling of the roof and the mining of the roof, floor, and rock bands. Both the miner and the bolter may be on a reduced standard, but compliance is easiest to achieve on the bolter, for which improvements in maintenance and operator practices are usually sufficient. At the miner, the problem is more elusive. Dust was produced not only by the cutting action but also by scooping, gathering, and loading operations. Research was completed to identify dust problem areas at the continuous miner5. An analysis of the potential for research in a number of dust control research project areas is also presented. The research areas address the respirable quartz dust problem at continuous miners.
