Continuous Microseismic Monitoring in a Deep Longwall Coal Mine.
Proc 4th Conf on Ground Control for Midwestern U S Coal Mines So IllinoisUniv PP 227-238 :227-238
The U.S. Bureau of Mines, as part of its effort to control seam and strata failures, is investigating the use of real-time microseismic monitoring to forecast mountain bumps and to evaluate the success of bump prevention and mitigation efforts. An automated microseismic monitoring system (amms) has been developed to collect mining- induced seismic event data. This technology has been employed in a deep eastern Kentucky coal mine experiencing infrequent, yet severe, coal bumps during longwall panel retreat. Analysis of the microseismic data suggests that information exists that may describe the "likelihood" of bump occurrence.
