The Article presents the results of long-term investigations of the problem concerning the protection of shafts with pillars of reduced sizes under conditions of the Talnakh and Oktiabrsky deposits. The principal potentiality of partial mining of shaft-bottom pillars VS-3 and GS has been proved at the Oktiabrsky ore mine. Certain recommendations are given on optimization of parameters of shaft-bottom protective pillars.
Consideration is given to the geological, mining and operating conditions of the Norilsk industrial district. The analysis is made of the present-day state of mining production of the subarctic branch of MMK «Norilsk Nickel». The principal trends in the safe and efficient exploration of the raw material resources base have been stated within the Norilsk industrial district .
Factors complicating drifting processes and barring in situ, disintegrated by tectonic burst- ing are considered. The analysis of stress-strain state formation of rock massif in the vicinity of tectonic disturbance is presented and practical recommendations concerning drifting and barring are given.
