Abstract
The U.S. Bureau of Mines has actively conducted microseismic research in coal mines for many years. The purpose of this research is to provide the mining industry with reliable techniques to warn of imminent coal mine bumps and outbursts so that miners may evacuate dangerous areas prior to ground failure. In this paper, the Bureau's research program in microseismic monitoring is discussed, including recent achievements of microseismic techniques applied to recognizing impending catastrophic ground failure in coal mines and the development of an automatic digital microseismic monitoring system. Event source location accuracy in coal is examined providing recommendations for future research to improve source locations.
