Abstract
The Bureau of Mines has actively conducted microseismic research in coal and hard rock mines for many years. The purpose of this research is to provide the mining industry with reliable techniques to warn of imminent catastrophic ground failures so that miners may implement control measures or evacuate dangerous areas prior to their failure. This report examines the use and benefits of a three- tier microseismic monitoring system which includes a surface seismograph, a mine-wide system, and local geophone arrays. The direction that a Bureau research effort is taking in developing a fully digital automatic system is also outlined.
