It was completed analysis of the production situation for the development of mining at South-Belozersky field using the camera mining system with backfill. Analytical studies of stress fields around the primary treatment cells allowed to identify areas of stress concentration, which are located in the rocks of the hanging and lying laterally, in an array of ore and backfill. It was studied the effect of mining cameras inception depth for accommodating an array of rocks. Found that an increase in the depth of mining is accompanied by an increase in discharge zones and increased tension of the rock mass around the cameras. Revealed exponential dependences of the change of radial stresses for an array of ore.
