摘要
三维地震勘探技术能较好地解释煤矿采区地质构造发育情况和主采煤层的厚度与顶底板岩性等。通过对鄂尔多斯地布尔台煤矿三盘区开展高精度三维地震测量,建立了高分辨率等时地层格架,控制了4套主要可采煤层的宏观结构和厚度变化趋势,解释了2个宽缓褶曲构造、276条断层和3处煤层顶板异常区,并进行了勘探前后对比。研究为后期合理布置巷道及采掘工作面提供了地质依据。
Three-dimensional seismic exploration technology can better explain the development of geological structures in the coal mining area,the thickness of the main coal seam and the lithology of the roof and floor.By carrying out high-precision 3D seismic survey on the third panel of the Ordos Buertai Coal Mine,a high-resolution isochronous stratigraphic framework was established,the macrostructure and thickness variation trends of 4 sets of main mineable coal seams were controlled,and 2 wide gently folded structure,276 faults and 3 abnormal areas on the roof of the coal seam were compared before and after exploration.The research provided a geological basis for the reasonable arrangement of roadways and excavation face in the later stage.
