In the present research, the estimation of actual durability of a shaft lining is made, considering the influence of factor of water filtration through “cold” seams of lining. This study is carried out on two vertical shafts of Donbas mines on eight sample plots. The data on the actual strength of the concrete lining after excavation and after 10 years of operation of the shaft were compared. The analysis of the data showed that the zone of “cold” seams is characterized by a decrease in the strength of concrete lining and an increase in the coefficient of variation of strength. It is established that the exhaustion of the resource of the shaft lining in the zone of leaking “cold” seams will occur in 16,9 years after the start of operation of the shaft, which is 4,6 years earlier than in the central areas of the lining stope.
