摘要： 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。

Abstract: To solve the problems of Liu-zhuang coal mine the east wind well the third aquifer hydrological hole delayed overflow, the freezing parameters of the shaft, the hydrogeological conditions, and the investigation and analysis of the hydrological hole were investigated.The results indicate that The the main reason is the reported of the strata water abundance weak and large porosity and put forward the corresponding methods.
