Abstract: Jiulongchuan mining area was a deep loess area, it had complex geological structure, thick coal seam and large natural tendency, 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 results had an important value to ensure rational development form determination of coal mines, scientific arrangement of the working face, safety and high efficiency mining.
