摘要
近年来煤矿开采深度不断增加,在应用走向长壁采煤方法时往往伴随冲击地压的发生,尤其是在回采工作面与回采巷道连接的端头处冲击地压更为频发。从矿山压力规律、围岩性质变化以及弹性波的角度来对端头处冲击地压现象频发的机理进一步进行剖析,期望对相关的冲击地压防治工作提供一定的借鉴。
With the increase of mining depth, rock bursts often occurred in the application of long-wall mining method, and it is most frequent at the junction of the mining face and roadway especially. From the perspective of the mechanism of underground pressure law, the changing of the surrounding rock and the elastic wave, it try to carry analysis on frequent occurring at the ends, expects to give a reference of prevention and control work related to rock bursts.
