Abstract
The Health Branch of the Pittsburgh Research Laboratory conducts research to reduce the dust exposure of mine workers through development of improved control technologies. In underground mining operations, ventilation continues to be utilized as a primary control by diluting dust levels and carrying air- borne dust away from mine workers. However, as mining conditions and mining practices change, the application of ventilating air must also be evaluated to achieve optimum results. For longwall mining, laboratory tests were conducted to evaluate the impact of increased air velocity on dust entrainment during shield advance and to evaluate the impact of air velocity changes in controlling dust generated by the shearer. In underground limestone mines, research is being conducted to evaluate the use of an auxiliary fan to control dust generated by an underground crusher and evaluate the impact of adding stoppings to better control air movement and isolate dust generating sources. Research procedures are discussed and test results summarized.
