摘 要:为使得冲击地压解危措施更加具有针对性、科学性,采用波兰PASAT-M便携式微震探测系统对东滩煤矿3305工作面开展冲击危险源探测,基于探测结论开展解危措施。探测结果表明:3305工作面探测区域内分布中等冲击危险源4处,弱冲击危险源3处。基于3305工作面冲击危险源分布,精确划定了轨道顺槽2处冲击危险区和胶带顺槽3处冲击危险区的范围,明确了危险等级。同时根据实测震波数据散点图,拟合得出3305工作面围岩纵波平均波速为3.88m/ms。探测成果成功指导了工作面冲击地压解危工作的实施,具有较好的示范效应。In order to make the measures of shock ground pressure relief more pertinence and scientific, the portable microseismic detection system of Polish PASAT-M is used to detect the impact hazard source in NO.3305 face of Dongtan Coal Mine. The results show that there are4 moderate impact hazard sources and 3 weak impact hazard sources in the detection area of the working face. The results show that the distribution of the impact hazard sources is based on the distribution of the impact hazard sources in the NO.3305 working face. The range of 2 impact danger areas and 3 impact hazard zones of belt belt are accurately delineated, and the danger grade is defined. Meanwhile, according to the scattered plot of measured seismic wave data, the NO.3305 working face is fitted. The average velocity of the longitudinal wave in surrounding rock is 3.88 m/ms. The detection results have successfully guided the implementation of the work of rock burst relief and have a good demonstration effect.
