三维地震勘探技术在煤层厚度预测中的应用

Application of Three-dimensional Seismic Exploration in Prediction of Coal Seam Thickness

以补连塔煤矿五盘区为研究对象,采用三维地震勘探技术对矿区主要煤层的厚度进行预测,以明确煤层赋存状况,为后续回采作业的安全、高效开展提供数据参考。结果表明:三维地震勘探技术实现了对主要可采煤层厚度变化情况的有效预测,并编制了相应的厚度变化趋势图,为后续回采工作的开展进行了一定资料积累,但由于勘测数据的局限性,对煤层厚度的预测仅为定性与半定量解释,所得结果即可作为参考。

Taking No.5 panel of Bulianta Coal Mine as the research object, three-dimensional seismic exploration technology is used to predict the thickness of main coal seam in mining area to clear the occurrence condition of coal seam and provide reference data for the safety and efficient development of the subsequent mining operation. Results show that three-dimensional seismic exploration technology realizes effective prediction of thickness variation of main mineable coal seam, and compiles corresponding thickness variation trend chart for the data accumulation of follow-up production work. But, due to the limitations of the survey data, the prediction of coal seam thickness is only qualitative and semi quantitative interpretation and the results just can be as a reference.
