A feature of the mining industry expansion in Russia and abroad is the persistent increase in the underground mine depth. Such mineral reserves are accessed by vertical shafts. One of the most difficult problems of mine shaft design is determination of the optimal parameters of lining. The calculation methods currently in application have individual advantages and disadvantages, as well as contradictions. Accuracy of the methods as well as efficient application domains reduces with the increasing depth of shafts and worsening geological conditions. In this connection, with regard to the unavoidable inaccuracy of geological information at great depths, it is promising to improve the analysis and calculation methods. In simultaneous sinking and lining technique, these methods can be implemented in the integrated monitoring system with subsystems for the analysis and prediction of stress–strain behavior of rock mass and lining. At the construction stage, the monitoring data are used to estimate adequacy of shaft design models and for live correction of project solutions. In the period of operation, the monitoring data allow technical evaluation of shaft and, given regular updating and analysis, enable prompt hazard identification and precaution.

Keywords: Mine shaft, stresses, strains, monitoring.
