刘庄矿东风井第三含水文孔溢水延期原因分析

摘要

To analyze the delayed hydrological hole overflow of the Third Aquifer during freezing construction of east ventilation shaft in Liuzhuang Coal Mine,the hydrogeological conditions,freezing parameters of the shaft were studied,and the hydrological hole was investigated and analyzed.The results indicated that the main reason is the weak water abundance and large porosity of the strata,and the countermeasures were proposed.%为了分析刘庄煤矿东风井冻结法凿井第三含水文孔溢水延期问题,研究了刘庄矿东风井水文地质概况.井筒冻结参数,并对水文孔进行了现场排查和分析.结果表明:造成水文孔溢水延迟的主要原因是地层富水性弱且孔隙率大,同时提出了问题的处理方法.
