The Research about Rapid and Safety Construction Technology of Shaft in Deep Alluvium and Deep Aquifer
Abstract：The depth of main shaft in Liliangdian coal mine is 771.2 m, which passes through the deep alluvial and deep bedrock aqui- fer. Through technical research, the whole design for deep freeze, frozen sections dig puzzle construction technology was proposed for the characteristics of the mine, which achieved a safe and rapid construction. The paper briefly describes the relevant research and ef- fectiveness. Shaft design and construction of deep freezing in deep alluvium and bedrock water of China were discussed.
