摘　　要：本文分析和总结了河南洛阳市某煤矿开展三维地震勘查工作成果,研究表明:矿区内含煤层位主要为下二叠统山西组(P 1 sh)二煤段的二1煤层,煤层平均厚5.36 m,含煤层位具有“东厚西薄”的特征;同时,根据三维地震数据共解译出14条正断层,断点清晰可靠,煤层底板形态为一平缓的向斜,褶皱构造简单,区内基本没有断裂构造,对煤层破坏程度较弱;含煤层位倾角较小,一般不大于15°,煤层厚度相对稳定。This paper analyzed and summarized the 3D seismic exploration of a coal mine in Luoyang,Henan Province The result showed that the embedded coal seam was mainly the 21 coal seam in the second coal member of the Lower Permian Shanxi Formation(P 1 sh).The average thickness of the coal seam was 5.36m.The coal-containing seam was"thick in the east and thin in the west".At the same time,according to the 3D seismic data,a total of 14 normal faults were interpreted.The fracture point was clear and reliable,The coal seam floor shape was a gentle syncline,and the fold structure was simple.There was almost no fault structure in the area,with weak damage degree to the coal seam.The dip angle of coal seam was small,generally no more than 15°,and the thickness of coal seam was relatively stable.
