Many problems result when coal mine shafts are built in complicated geological conditions and serious shaft lining ruptures have often occurred in the eastern part of China since 1987. Several types of treatment methods were used for shaft lining reinforcement such as grouting method, sets of wall reinforcement method and stress-relief slot method; based on an analysis of these methods and the mechanism of the shaft lining rupture, a new treatment method was proposed for shaft lining treatment with underground continuous impervious curtain. In this research, the various conditions of the UCIC built around the shaft lining were analyzed, and the effect of the (UCIC) range of improvement was discussed, then the optimum condition was determined. The results show that the effect of the UCIC for treatment depends on the range and width and also the material's property, the safety factor of the shaft lining can be the evaluation criterion and had great changes in the boundary of the different layers.
