Abstract：Before roadway excavation in high gas and high outburst mines, a variety of drainage boreholes should be adopted to pre-drainage coal seam gas. In order to realize the ' one hole multi-purpose ' of drilling, using a variety of state of drainage drilling to analyze and master the occurrence form of coal seam, so as to achieve the purpose of advanced control of coal seam, this paper analyzes the geological structure predicted by contour line of three-dimensional seismic coal seam floor, the trend of coal seam predicted by directional drilling, the revision of coal seam slope by cross-layer drilling, and the verification and detection results of working face detection drilling. The results show that the coal seam occurrence trend can be accurately mastered and controlled by analyzing various drainage drilling without special construction of coal exploration drilling.
