4 Health Effects of Exposure to Respirable Coal Mine Dust

This chapter describes the adverse health effects associated with exposure to respirable coal mine dust. Epidemiological studies of underground and surface coal miners in the United States and other countries are discussed. Also discussed are animal studies that add to our understanding of particle deposition and retention in the lungs and associated disease responses. This chapter emphasizes s...

Respirable quartz hazard associated with coal mine roof bolter dust

This study examined the potential for coal mine roof bolter dust to be a source of a worker’s exposure to respirable quartz. For the models of roof bolter studied, the dust from bolt hole drilling is collected by a dry vacuum exhaust system. The collected dust-laden air passes through a cyclone size-separator (pre-cleaner) and into a collector box containing two additional cyclones and a filter...

Airborne dust in coal mines: the sampling problem.

Equivalency of a personal dust monitor to the current United States coal mine respirable dust sampler.

The United States National Institute for Occupational Safety and Health, through an informal partnership with industry, labor, and the United States Mine Safety and Health Administration, has developed and tested a new instrument known as the Personal Dust Monitor (PDM). The new dust monitor is an integral part of the cap lamp that coal miners normally carry to work and provides continuous info...
