Feasibility Analysis on Using Shaft in the Region with Large Deformation
Based on results of deformation monitoring and numerical simulation, feasibility of using shaft in the region with large deformation is discussed. The results obtained show that: although the original is big, and the deformation of rock around the shaft will continue to increase. The tilting of shaft will seriously affect the cages running up and down. However, the total deformation is still in a certain range, general damage of rock mass around the shaft wont occur in the near future. By taking some measures to stop rock deformation speeding up, to reinforce the structures and the foundation of shaft, derrick and hoist room, to promote safety management, coupled with comprehensive, systematic and continuous site monitoring and prediction, the East Main Shaft can continue to be used. The post-use of shaft validates the correctness of the findings. To accurately explore the feasibility of using shaft, some basic work as comprehensive grasp of engineering geology conditions, in-depth insight into the rock deformation characteristics and mechanism, and accurate prediction of rock deformation are really required. The research method and results obtained may be of referential value to similar projects.
