大同煤田地质构造综合探测技术应用

Application of Integrated Geological Struc tural Prospecting Technique in Datong Coal field

随着采煤机械化程度的不断提高,采区设计和工作面的回采越来越受到地质构造的制约。有效使用大地电磁测深、高分辨地震、槽波地震、坑道无线电波透视等勘探技术,收集巷道揭露资料和井下摄影编录资料进行综合分析,结合井下构造力学解析法,对采区及综采或掘进工作面的地质构造进行探测,并应用定向钻进技术对探测结果进行验证。实践证明,这种综合探测技术可有效地探测地质构造及地质异常体。

In the wake of coal mining mechan ization has carried to a new and higher leve l, the wining district design and working fa ce extraction are more and more restricted by geological conditions. So it is necessar y to use techniques such as magnetotelluric sounding, high resolution seismic, in-seam seismic, underground electromagnetic wave perradiator etc. combined with information revealed in workings and underground photo graphic documentation as well as structura l mechanics analysis to prospect geologica l structures in wining districts and fully mechanized mining and heading faces, finall y to verify at last all of the prospecting r esults by directional drilling technique. The practice demonstrated that this integr ated prospecting technique could effective ly find out geological structures and anoma lous geologic bodies.
