CAO Hua-chun
Abstract：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.
