摘　　要：大连董家沟煤矿地下存在多处采空区,因建设治理需要,采用地震波CT技术对其进行采空区分布状况探测。通过探测,结合收集的其他资料,共圈定董家沟煤矿研究区域内地下34处异常区域,经钻孔验证准确率高达87.5%,取得了很好的效果。There are many hollow areas underground of Dongjiagou coal mine. Due to construction, the distributions of these areas are detected by seismic CT （ Computed Tornography） technology. CT technology of elastic wave which adopts the basic principle of section X - ray scanning is a kind of new method of geophysical exploration. We can get the distribution information of physical parameters of rocks or soil underground by different responses of boundaries to elastic wave. Thiay - four hollow areas are delineated in the study area of Dongjiagou coal mine by CT detecting and some other information. From drilling testing, the exact ratio of location reaches 87.5 %.
