In the light of more and more serious water hazard problems in Huangling mining area, according to analyze the hydrogeology condition and water-filling factors of Huangling No.2 mine, this paper selected the formula in the Standard on the Exploration of Hydrogeology and Engineering-Geology in the Mining Area (GB12719-91) (Standard for short) to calculate the height of water flowing fractured zone in coal seam No.2. On the basis of the Shangzhenzi and Baiyaogou water source, a scientific risk evaluation system for the roof water-bursting condition during mining coal seam No. 2 is established, and a division scheme for the condition is also put forward. The paper points out that a water inflow risk area is composed by 14 drillings (R65, Fx1, Fx7 and so on) which is approximately 30.6km2 in the southwest of predate mining district. The study provides basis for carrying out “The twelfth five-year plan” of the mine.
