Managing excess gas emissions associated with coal mine geologic features.
Handbook for methane control in mining. Kissell FN, ed. Pittsburgh, PA: U.S. Department of Health and Human Services, Public Health Service, Centers for Disease Control and Prevention, National Institute for Occupational Safety and Health, DHHS (NIOSH) Publication No. 2006-127 (IC 9486), 2006 Jun; :97-112
This chapter summarizes how certain geologic features may be associated with unexpected increases in gas emissions during coal mining. These unexpected emissions have the potential to create explosive conditions in the underground workplace. This chapter summarizes current technologies for recognizing and remediating gas emission hazards associated with various geologic features. Although emphasis is placed on recognized hazards in U.S. coal mines, hazards not well-documented in these mines, such as gas outbursts, are also discussed due to the potential for such occurrences in the future as mines extract deeper and gassier seams.
