Abstract:
A mine 2120 fully mechanized caving face has a moderate rock burst hazard, the seam has a weak rock burst risk characteristics, and large energy shock events occur frequently in 21 mining area in the mining process. Based on the data analysis from SOS microseismic and ARES-5/E ground sound monitoring system, the paper puts forward a multi-parameter coupled analysis to forecast high energy shock, and through the coupling of Z-MAP value,
A(t) value, AP value, activity value
S and G11 channel acoustic emission data, the paper gets the coupling rule between a variety of indicators and AE, and accuracy reaches more than 75%.
