Concepts to control quartz-dust exposure of the continuous-miner operator and helper. Open File report (Final)
Reduced respirable dust standards are imposed on U.S. coal mines when the quartz content of the dust exceeds 5%. Traditional approaches to dust control often fail to allow standards below 2.0 mg per cu m to be met. Several control techniques were identified to reduce the dust exposures (including quartz) of the continuous miner operator and other face personnel. These include the use of higher water flow rates to reduce the quantity of dust generated during cutting, improved spray systems, improved cutting and loading practices, improved use of ventilation curtains, and improved spray systems to reduce dust from secondary sources. The report describes the laboratory development, engineering analyses and underground evaluations of these control techniques.
