地震反演技术在预测煤矿古河流冲刷带中的研究和应用

摘要

安居煤矿井下揭露了多处煤层变薄区域，技术人员通过作图分析，推测变薄区域应为一条整体南北走向的古河流冲刷带。利用地震反演技术做出了3上煤层煤厚变化趋势图，该图显示的煤层变薄区域与推测区域基本一致，并得到了现场实际揭露情况的进一步验证。事实证明：地震反演技术的预测资料成果对矿井开拓布置和工作面开采起到了较好的指导作用。%multiple seam thinned area have been exposed in the underground mine, and analyzed by the technical personnel. It is assumed that the thinning area should be an ancient river erosion zone. Using the seismic inversion technology to made the 3 coal seam thickness change trend chart, the chart shows that the thinned area and the speculation area is basic accordance, the actual disclosure of the site further verify the situation. It is proved that the results of seismic inversion technique can guide the development of the mine and the mining of the working face.
