Prediction of Hard Brittle Geological Disasters in Metal Mine from Microseismic Monitoring

Abstract

During the past decades, the microseismic technique has changed from a simple researching means for rock failure study to a practical method for daily safety monitoring at high geo-hazard tendency mines. This paper introduces the microseismic monitoring system built at a metal mine aiming at the prediction of the geological hazard. The arrangement of microseismic monitoring sensors should take consideration not only of the current mining situation, but also by the aid of experts experiences. By a successful case of prediction for hard brittle failure, the Shizhuyuan microseismic monitoring system was proven to be valid and necessary in the prediction of geological hazard.
