| Abstract: | It is very important to determine the limit excavation depth of a circular shaft according to the strength characteristics of rockmass. This paper describes the calculation method of wall rock stress of a shaft. Based on the rule of empirical strength, rock failure is described and the calculation method for shaft limit excavation depth is deduced. |
