摘要
煤、岩层的冲击倾向性是评价冲击危险性的主要特征参数。对赵楼井田3煤的冲击倾向性直接根据其KE,WET和Dt的测试结果进行判别;顶板的冲击倾向性则主要根据顶板分层的UWQ及复合顶板的UWQ进行判定。试验结果表明:井田3煤具有强冲击倾向性,顶板岩层具有弱冲击倾向性。
Impact proneness of coal and rock is mainly characteristics parameters to evaluate the rock burst hazard.The impact proneness of No.3 coal seam in Zhaolou mine field was directly discriminated according to the KE,WET and Dt test results.The determination of roof rock impact proneness is mainly based on the UWQ of roof layeres and compound roof.Experimental results show that No.3 coal seam has highly impact proneness and roof rock has weakly imburst proneness.
