Present approaches to structural assessment of concrete lining in vertical mine shafts: Review

Concrete and reinforced concrete lining of vertical mine shafts is one of the critical components which ensure the strength and safety of a shaft structure. Concrete lining of mine shafts in long-term operation is as a rule characterized by fracturing and failure development in time, which shows up in the form of initiation and widening of fractures, roof breaks and rock falls, general deformation (convergence) and drop in residual strength of concrete. Deformation and failure of concrete govern performance level and safety of lining, and also affect stiff reinforcement composed of buntons and guides. For this reason, structural assessment of concrete lining is an important task to ensure safe and efficient performance of shafts and of the whole mines. The present method of structural assessment of concrete lining in mine shafts are divided by the authors into two main blocks–field observations and instrumental measurements (non-destructive and destructive testing, geophysical measurements, geodesy). The method of numerical modeling of deformation processes is discussed. The main shortcomings of some methods are analyzed. A conclusion is drawn to develop an integrated approach to the current structural assessment of concrete lining in mine shafts.
