厚黄土覆盖浅埋煤层区域三维地震勘探技术

3D Seismic Exploration Technology for Shallow Coal Seam Covered with Thick Loess

在简述渭北黄土高原内白水煤矿地质概况的基础上,分析了厚黄土覆盖浅埋煤层区域进行三维地震勘探的难点,讨论了关键技术。论文论述了在观测系统设计、资料采集及资料处理过程中的关键技术。结合验证资料,证明了在厚黄土覆盖浅埋煤层区域进行三维地震勘探是可行的。

Based on a brief description of the geological situation of Baishui Coal Mine in Weibei Loess Plateau, this paper analyzes the difficulties in carrying out three-dimensional seismic exploration in the shallow coal seam area covered by thick loess,and discusses the key technologies.This paper discusses the key technologies in the process of observation system design,data acquisition and data processing.Combined with verification data,it is proved that it is feasible to carry out 3D seismic exploration in the area covered by thick loess and shallow coal seam.
