将冲击地压地音前兆信息识别方法建立在冲击地压机理分析的基础上，提高了冲击地压预测预报的理论依据和可靠性。通过对大量现场实测地音数据分析，获得了顶板断裂型、采动高应力型和断层活化型冲击地压的典型地音前兆模式。突变型地音模式适合于用来预测顶板断裂型冲击地压，灵敏性较高；持续稳定型则一般不会出现非稳定的突变状态，适合采动高应力引发的冲击地压预测；波动型地音模式包含类似主震－余震型和前震－主震型两种，适合于断层活化型冲击地压预测。
將遲擊地壓地音前兆信息識彆方法建立在遲擊地壓機理分析的基礎上，提高瞭遲擊地壓預測預報的理論依據和可靠性。通過對大量現場實測地音數據分析，穫得瞭頂闆斷裂型、採動高應力型和斷層活化型遲擊地壓的典型地音前兆模式。突變型地音模式適閤于用來預測頂闆斷裂型遲擊地壓，靈敏性較高；持續穩定型則一般不會齣現非穩定的突變狀態，適閤採動高應力引髮的遲擊地壓預測；波動型地音模式包含類似主震－餘震型和前震－主震型兩種，適閤于斷層活化型遲擊地壓預測。

The method of precursor information identification of rock noise was developed on the basis of mechanism analysis of rock burst,and it improved the theoretical basis and reliability of forecast and prediction of rock burst. According to a large number of rock noise data from field measurement,three typical rock noise precursor patterns were confirmed,respectively were roof fracture type,high stressing mining type and fault activation type. Mutant type rock noise pat-tern was suitable for forecasting the rock burst of roof fracture type and it had high sensibility;the sustained and stable type was generally not a non-steady state of mutation and suitable for forecasting the rock burst caused by high stressing mining;the fluctuating type pattern contained similar mainshock-aftershock type and foreshock-mainshock,which was suitable for fault activa-tion type.
