TECHNOLOGYCAL PARAMETERS OF BOOKMARK PROCESS OF THE WORKED-OUT AREA DURING MINING OF COPPER-NICKEL ORES OF TALNAKH DEPOSITS IN THE MINE “SKALISTIY”

Gabaraev O.Z, Lolaev A.B., Hubulov O.Ju.

Results of researches of the stress-strain conditions of the ore accommodating massif and technological parameters of bookmark process of the worked-out area at underground working of great broken state ores are presented. Variants of continuous chamber dredging with advanced unloading on a roof of ore body and with placing of a protective layer from the highgrade hardening mixture with durability not less than 3,5-4 MPа in places of the greatest broken state of the ore accommodating massif are developed. Recommended  technological decisions provide efficient control a condition of the ore accommodating massif, resource economy and safety of working off thick gently sloping ore bodies due to increase of bearing ability of filling mass and decrease in expenses for their erection.
