塔拉壕煤矿精细三维地震勘探处理技术应用

Application of 3D Seismic Exploration Technology in the Coal Mine of Ta Lahao

为解决塔拉壕煤矿地形复杂,黄土厚度横向变化大,造成区域地震资料信噪比低,以往成果准确度无法满足井田的生产指导的问题,通过合理处理方法、流程、参数选择,在保真的前提下,极大提高资料的信噪比、分辨率,最终解释成果(断层、巷道)与采掘对比揭露准确率显著提高,为煤矿的安全开采提供可靠的依据,并总结出适合此区精细三维地震勘探处理的技术方法。

In order to solve the problem that the terrain of talahao coal mine is complex and the thickness of loess changes greatly laterally,resulting in the low signal-to-noise ratio of regional seismic data,and the accuracy of previous results can not meet the production guidance of the mine field,the signal-to-noise ratio and resolution of data are greatly improved by reasonable processing method,process and parameter selection on the premise of fidelity,and the final interpretation results(faults,roadways)are compared with mining results The accuracy of exposure is improved significantly,which provides a reliable basis for the safe mining of coal mines,and summarizes the technical methods suitable for the fine 3D seismic exploration processing in this area.
