Abstract:In order to solve the technical problems of freezing shaft sinking in special thick alluvium in Main and Auxiliary Mine shafts, site measurements of inner and outer stresses of the outer shaft wall were conducted during the shaft sinking. The site measured data of freezing clay pressure below 400 m were obtained. After the information feedback, a dynamic design and informational construction was made for the two mine shaft construction.
Keywords:thick alluvium  ground freezing method  out wall of mine shaft lining
