摘　　要：九龙川矿区属于深厚黄土区,地质构造较复杂,煤层厚度较厚,自燃倾向性大,常规煤田地震采集方法获得的地震资料难以达到采区地震勘探的"三高"要求。针对九龙川矿区实际特点,采用合理的三维地震勘探方法和地震资料处理方法准确的对矿区内复杂的地质构造、煤层分布等进行分析,研究结果对保证煤矿合理开拓方式的确定、工作面科学布置和安全高效开采具有重要价值。Jiulongchuan mining area was a deep loess area, it had complex geological structure, thick coal seam and large natural tend- ency, so the conventional coalfield seismic acquisition method was hard to achieve seismic exploration requirement of high signal - noise ratio, resolution and fidelity in mining area. According to the actual characteristics of Jiulongchuan mining area, it analyed complex geological structure and coal distribution in mining area accurately by using reasonable 3D seismic exploration and seismic data processing method. The resuhs had an important value to ensure rational development form determination of coal mines, scientific arrangement of the working face, safety and high efficiency mining.
