摘　　要：在煤体中P波的传播速度较S波快,且到达时间易于识别。基于此,以P波到达时间为主要依据,采用牛顿迭代法求解矿震震源定位的非线性方程,并利用MATLAB编写独立可执行文件对其进行程序实现。应用该程序对华丰煤矿的一次矿震事件进行震源定位,其定位结果与实际数值基本吻合,较为准确的测出震源的空间位置,相互得到验证,图形输出形象直观。The velocity of P wave is faster than the S wave and the arrival time of P wave is easy to distinguish in the coal. Based on this, Newton iteration method is used to solve the nonlinear equations of hypocentral location on the basis of the arrival time of P wave, and MATLAB language is used to compile a stand - alone executable program for this solution process. The result is more accurate and more intuitive graphical output when it used for hypocentral location in a mine earthquake of Huafeng coal mine. The results could be basically meet the actual value and could be mutually confirmed.
