【摘要】 在合理利用地形的条件下,地震层析成像方法能够对小尺度构造现象进行有效的观测和追踪。本研究突破了地震层析成像方法在地下调查时常采用的地表-井孔、井间、坑道等观测方式,适当地利用矿田地形实现了近似全方位的地震层析成像野外数据采集,对隐伏含金石英脉及其围岩成功地实现了地震波速度结构的重建。更多还原

【Abstract】 If the terrain were put a rational use,a buried lodge of width less than 1m could be offectivly observed and traced by making use of the high resolution seismic CT methods.This research makes a break throught on the common seismic CT observing ways,such as surface-hole,between holes,pit and so on.It proerly takes advantage of the orefield terrian and approximately bring about omnibearing seismic CT field data cellecting. Morever,it also brings about the quantitutive observing of the buried gold-bearing quartz veins by using the non-homogeneous media rays tracing methods.更多还原
