Abstract：Based on control theory of geological construction, the actual measurement and geological logging are developed, the occurrence regularity of geologic construction is analyzed, the influence factors of gas occurrence, such as the geologic structure, the rock character of roof and floor, the burial depth of coal-bed, hydrogeology conditions and so on are researched, by collecting the geologic and gas data systematically.The gas content distribution law and the distribution of tectonic coal are revealed, and the outburst danger of No.15 coal seam in Huangyanhui mine is predicted.The research shows that: the burial depth of a coal-bed is the main control factor that affect the gas content distribution of No.15 coal seam in Huangyanhui coal mine, and other geological factors affect the local variation of coal seam gas;the buried depth being greater than 321m for No.15 coal seam is divided into an outburst dangerous area, and the rest is a non-outburst danger district.
