复杂构造区域影响下的冲击机理研究与实践

Research and Practice of Rock Burst Mechanism Under the Influence of Complex Tectonic Zone

以运河煤矿6303工作面为研究背景,实践考察和理论分析指出其工作面在复杂构造区影响下有较大发生冲击地压的可能,根据6303工作面的实际情况研究了该类型下的冲击地压发生机理,并通过RFPA软件数值模拟了2种采煤方法下的冲击危险情况,确定出了合理的采煤方法。最后,工程实践采取合理的卸压措施保证了该工作面的安全回采。

Taking Yunhe Coal Mine 6303 working face as the research background, the practical investigation and theoretical analysis show that the working face has great rock burst risk under the influence of complex tectonic zone. We studied the mechanism of rock burst under this type according to the actual situation of 6303 working face. And through the RFPA software,we simulate the rock burst risk of two mining methods and determine a reasonable mining method. Finally, the engineering practice takes reasonable unloading measures to ensure the safe recovery of the work surface.
