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。
The impact propensity of coal and rock formation is the main characteristic parameter to evaluate the impact risk. The impact propensity of No.3 Coal in Zhaolou Minefield is judged directly based on the test results of KE, WET and Dt. The impact propensity of roof is mainly determined by UWQ of roof delamination and UWQ of composite roof. Test results show that coal mine 3 has strong impact tendency and roof rock has weak impact tendency.
