【摘要】 阐述了水文地质条件改造意义,结合太平煤矿近松散层疏放开采的实际水文、地质条件,试验研究了矿井水文地质条件,提出了地面供水井封堵和井下疏放结合的综合开采方案,阶段性地实现了第四系上组水的开采保护和井下安全生产,对进一步疏放开采亦具有重要的指导意义.更多还原

【Abstract】 Significance of transforming hydrogeological conditions is discussed. The hydrogeological conditions of Taiping coal mine was experimentally researched. A comprehensive mining method is put forward in which the water is stopped from flowing into the coal bearing strata while the water in coal mine is drained. By doing so, the safety production has been realized in explotimg coal over Quarternary strata, which can be used as a reference for other coal mines with the same hydrogeological conditions.更多还原
