The shaft lining failure which occurs in deep alluvium is a sudden coal mine hazard.
The strata grouting is one of the treatment methods for the shaft lining failure.
To investigate the impact of grout injection pressure on the shaft lining, the field measurement and the numerical analysis of the shaft lining stress variation during the grouting were conducted.
To improve the strata grouting, the underground continuous impervious curtain (UCIC) is proposed as a new method by using the chain conveyor cutter technique without the impact on the shaft lining.
The effects of the new method were also analyzed by means of the numerical methods.
The results show that the strata grouting in the deep alluvium needs a high injection pressure, and in the horizontal direction, the shaft lining sustains the repeat tensile and compressive force during the grouting process.
The negative influence of strata grouting on the stability of the shaft lining is obvious and serious.
The UCIC built around the shaft lining can restrain the stress concentration induced by the aquifer drawdown.
The triangular UCIC has a similar effect as that of the vertical one, and the small angle is better for preventing the shaft lining failure.
