槽波地震透射法和反射法在断层探测中的联合应用

为提高井下槽波地震勘探对工作面内部断层探测精度，解决采用单一透射法探测物探异常区效果不理想问题，提出透射/反射联合勘探的施工方法，对工作面内部进行透射法勘探，并对拾取的Love型槽波旅行时进行层析成像，绘制槽波波速分布图，从而判断地质异常体的有无；同时进行反射法勘探，利用Rayleigh型槽波解译数据，确定断层位置及大致衍生方向。实践表明，两者联合使用可以获取更加丰富的地质信息，确保了勘探成果的准确性。

Combined application on fault detection by transmission and reflection of inseam seismic survey

To improve the precision of structure detection by inseam seismic survey，and to solve the problem that detection result is not very good by one method，joint exploration had been applied for detecting the existence of geological anomalous body by transmission method，then the travel time of Love wave had been picked up，and the travel time were used to do computed tomography，and drawing the contour of velocity of channel wave，thus existence of anomalous body could be judged. Meanwhile，Rayleigh wave was analyzed for detecting the position and extending direction of structure by reflection method. The study showed that abundant geological information could be got by joint exploration method，which ensured the detecting accuracy.
