摘要
顶板破裂会激发弹性波。测量有关破裂的位置,不仅有助于对危险区做出正确评价和判断,而且也可对灾害的发生做出预测并及时报警。在矿山微地震定位中,地震波的走时计算的精确性对定位的效果起着至关重要的作用。作者基于射线追踪理论,研究了在矿山微震事件中首波走时的计算,从而实现了首波在射线追踪过程中的应用。
Roof fracture can excite elastic waves. Determining the location of fracture not only could evaluate the dangerous area correctly but also gives timely disaster forecasting and alarming. Calculation accuracy of seismic waves＇ travel time is the key to the mine microseism location. Based on the ray tracing theory, the author studied the travel time calculation of first arrivals in mine mieroseism and realized the application of first arrivals in the process of ray tracing.
