反射槽波地震勘探技术在煤矿采空区探测中的应用

为了探测煤矿井下采空区及空巷的准确位置，以山西煤炭运销集团拓新煤业有限公司井底车场附近未知区域为研究对象，采用反射槽波地震勘探技术对区域内地质报告中已划定的采空区进行探测，最终在成像结果中圈定了采空区、空巷的空间分布。经钻探验证，其结果与勘探结果相符，为矿井建设过程中井底车场、中央变电所、水泵房及水仓的设计变更提供了技术支撑及安全保障，从而缩短了建设工期，并节省了经济成本。

Application of Reflected Trough Wave Technology in Detecting Goaf of Coal Mine

In the process of mine production, the accuracy of the location of old goafs and gob areas have always been the key issue affecting the mining design, construction and the safety of production. This article takes unknown area of underground yard of Shanxi Coal Transportation and Marketing Group Tuoxin Coal Industry Co., Ltd as research object; and using seismic exploration technology of reflected trough wave to detect the goafs which are defined in . The final imaging results of the research effectively delineated the distribution of goafs and gob areas which is verified by drilling results. The research indicates that the channel wave seismic exploration clearly delineates the distribution of suspect goafs and gob areas. Reflected trough wave technology provides technology support and safety guarantee for the design of underground depot, central substation, pump house and water tank during the process of mine’s construction, which shortened the construction period resulting effective reduction in investment requirement.
