用地震定位方法研究矿山爆破中的地震波传播速度
|
摘要
综合叙述了地震定位方法研究地震波传播速度的3个步骤:走时方程线性化,解线性方程组以及将计算结果作为预设初始值利用Powell算法进行优化。分析讨论了3种检波器典型几何分布的观测系统,得出检波器十字型分布观测系统精度最高的结论。并将检波器十字型分布观测系统应用到野外矿区实际地震资料采集中,利用矿山施工时的爆破作为震源。此次研究,所用检波器数目多,分布范围广,所得结果精度高。
Comprehensive description of the earthquake location method for studying seismic wave velocity has been done: linearization of the travel time equation,solving linear equation and optimizing the result which is used as default initial value by Powell algorithm.Three kind of typical geophone geometric distribution observation systems have been analyzed and discussed,resulting in a conclusion that the geophone cross-shape distribution observation system is most accurate.The geophone cross-shape distribution observation system has been used in seismic acquisition in the mining field,and the explosion at the time during the mining production is used as the seismic source.Plenty number of geophones which is widely distributed are used in this study,and the result is accurate.
