Abstract:Coal seam roof water inflow accidents occur frequently, which poses a great threat to mine safety production. Taking Henggou field in Wubao Mining Area of Shaanxi Province as an example, on the basis of analyzing the hydrogeological characteristics of the mine, the ' three figures-double prediction method ' was used to comprehensively analyze the water abundance and cracking safety of the water-filled aquifer of the coal seam roof, and carry out the roof water outburst risk assessment and zoning of the main coal seam of S group. The evaluation results showed that the more dangerous and sub-dangerous areas of mine water inflow were distributed in the southern, southeastern and central parts of the mine field, and there were small-scale dangerous areas in the central and southern parts of the mine field. The relatively safe area and the relatively safe area were mainly located in the northern and central parts of the minefield, and the remaining areas were transitional areas.
