Analysis of Cutter Roof Failure Induced by Clastic Dikes in an Underground Coal Mine
Cutter roof failure, a ground control problem that frequently results in massive roof failure, is common in coal mines of the Northern Appalachian Coal Basin, causing delays in production and posing a safety hazard to mine personnel. The Bureau of Mines is conducting research on the causes of cutter roof failure to gain a basis from which to predict and prevent its occurrence, and to support such roof when failure occurs or is imminent. Research revealed a correlation between the presence of clastic dikes and formation of cutter roof failure. Staggering of crosscuts prevented the extension of cutters and deterred the occurrence of large falls extending over several break-throughs. In addition, trusses and cribbing were effective in stabilizing clastic dikes and inhibiting the development of cutter roof failure when employed immediately or shortly after mining.
