THE FUTURE OF MICROSEISMICITY MONITORING IN MINES: BEYOND THE “DOTS”

World Mining Congress
Introduction Development Then - ‘Dots’ on a map •[e.g.] Abnormal microseismic activity rate change a long-term indicator of rock burst hazards; helps to identify highly stressed areas of a mine highlights pre-existing weaknesses in the rock mass Now - Improved understanding of microseismic event sources •Improved source locations and source parameters •Realization of microseismic source mechanisms & Future - Further improvements in the accuracy and precision of microseismic source characteristics - Application of event source characteristics information to advanced analyses on: •Clustering, collapsing, and feature identification •Seismic strain-rate distribution in 5D •Spatio-temporal distribution of source mechanism types •Geotechnical implications Discussion & Conclusions
Keywords: Mines; Mine; microseismicity; Distribution; underground mine; underground mines; analysis; Rocks;
