NIOSH comments to DOL on the Mine Safety and Health Administration's report, 'Belt Entry Ventilation Review: Report of findings and recommendations' by R. W. Niemeier, November 22, 1989
Technical Report
·
OSTI ID:5538235
The testimony concerns the use of belt entry air to ventilate the working faces of mines. NIOSH does not view this practice as safe and cautions that the studies cited be interpreted in the context of using belt air to ventilate the working face. This would require that high velocity intake air be coursed through the belt entry. The inference of several studies is that the introduction of high velocity intake air into the belt entries will increase the disbursement of float coal mine dust and increase the fire and explosion hazards associated with float coal mine dust. The data in the MSHA report indicated that longwall mines using belt air to ventilate the working face exceed the 2mg/cu m mean respirable dust standard in 35% of the samples. Longwall mines without belt air exceeded 2mg/cu m in 23% of the samples reported. Current reports indicate increased risks of developing pulmonary massive fibrosis from exposure to 2mg/cu m or 1mg/cu m, and that means of reducing these levels even further should be sought.
