OFR-82-92 Documentation Of Mining Techniques Used To Mitigate Mountain Bumps

Mountain bumps have been a problem in the coal-mining industry since the 1920's. The problem became severe in the late 40's and early 50's with the introduction of mechanized mining. Fatalities and serious injuries resulted from mountain bumps during this period. Mountain bumps again caused fatalities in the 80 's. Interviews were conducted mostly with retired coal miners having experience in bump conditions with five different coal companies. These men held positions as president, general manager, roof-control specialist, mining engineer, inspector, superintendent, mine foreman, shift foreman, section foreman, miner operator, electrician, and general laborer. Together, their comments give a good idea of the things tried to mitigate mountain bumps in the Appalachian Coal Fields.
