【摘要】 某矿2120综放工作面具有中等冲击危险性,所采煤层具有弱冲击危险特征,所在的21采区采掘过程中大能量震动事件频繁发生,通过对该矿SOS微震和ARES-5/E地音监测系统数据分析,提出了采用多参量耦合分析预测预报大能量震动的发生,并通过Z-MAP值、A(t)值、AP值、活动度S值与G11通道声发射数据耦合,得到了多种指标与声发射之间的耦合规律,准确性达到75%以上。更多还原

【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%.更多还原
