摘要
Abstract
Based on analyzing the hydrogeological conditions and the water filling factors of Huangling No. 1 mine, it is considered that sandstone aquifer of the lower Zhilo Formation is main water source for water inflow (inrush) of No. 2 coal seam roof. A comparative analysis of the heights of caving zone and fractured zone ("two zones" for short) by empirical formula and measured value, we conclude that the empirical formula disagree with the mining practice in this area, and determine the caving/mining height and fractured/mining height is 5. 7 and 25. 2, respectively, for this area. With the ratio of fractured/ mining 32, partitioning prediction of the risk of roof water inflow (inrush) at coal seam No. 2 in the north centre of the mine field is completed to provide basis for mine water hazard control.关键词
