利用井间地震层析方法探测地下洞穴——主要工作参数的选取与应用

在矿山采空区等地下洞穴探测方面,井间地震走时层析方法是目前最有效的物探方法之一。从方法过程和基本应用条件出发,结合工程实践,对观测系统设计,激发与接收,施工工艺,数据采集与处理等环节的工作参数选取进行了分析,并通过应用实例说明了该方法在采空探测方面的良好效果。

Using Cross-Borehole Seismic Tomography to Detect Underground Cave——Application and Selection for Some Important Survey Parameters

Cross-borehole seismic travel time tomography is one of the best effective geophysical methods in detecting underground cave such as mines for coal.In this paper,combining the engineering practice,it analyses observation system design,stimulating and receiving,construction technique,data acquisition and processing and other working parameter.In addition,it introduces the good effect of the method in the detection of the mined-out areas.
