【摘要】 为了获取监测区域微震信号传播波速,基于P波残差理论,通过爆破试验标定波速的方法,研究了微震信号传播波速的标定原理及方法,并优化了监测区域P波波速,提高了震源定位精度。结果表明:该方法与传统的以实验室所测试样波速进行定位计算相比,能够较为真实地反映出监测区域的煤岩体波速。上述结果能很好地提高微震技术在煤岩体稳定性评估方面的监测效果。更多还原

【Abstract】 In order to obtain micro-seismic wave velocity,this paper researched calibration principle and method of micro-seismic wave velocity by blasting tests on the basis of p-wave residual error theory,and optimized p-wave velocity in monitoring area so as to improve seismic source location precision.Results showed that this method could more precisely calculate coal and rock wave velocity,compared with traditional test method in laboratory.It could improve monitoring effect of micro-seismic technology in coal and rock stability evaluation.更多还原
