An engineering layout suitable to drill sharply inclined coal-bearing strata：with Luoyuan mine field in Huainan coalfield as an example

Through the analysis of tectonic styles controlling the coal seam distribution in LuoYuan Mine Field, and in the background of high precision and fast exploration, and in preconditions that the function of conventional seismic exploration mean was restricted, combined with standard requirement, we chose more objective and reasonable exploration technique suitable for the exploration of this particular form of resource storage in this coalfield. And we confirmed the drilling engineering layout mode, which was combined with directional inclined borehole and vertical borehole, and put it into practice. It reduced the exploration cost, improved exploration work efficiency, and obtained more obvious technical and economic benefits.
