摘要
Abstract
In view of the actual shape, aquosity, permeability of exposed collapse columns in 4325th work face crossheading of Daizhuang Coal Mine, based on the hydrologic and geological characteristics, EH-4, pit prospecting,underground drilling were adopted to analyze hydraulic connection between collapse column and aquifers.Results show that collapse column is almost of normal oval shape on plane with semi-major axies about 20m, semi-minor axies about 13m; sandstone aquifer over the top of collapse column has certain static reserve, but limited supply; no hydranlic connection is found between collapse column and each aquifer, so it is defined as weak water-filling collapse column.The results provide a guarantee for safe mining of 4325.关键词
