Partitioning Prediction on the Risk of Water Inflow of the Roof in Huangling No.2 Mine

Abstract:

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.
