The geomechanical conditions of the mined and commissioned ore deposits are determined and systematized on the basis of their typification according to geological and structural features, which are characterized by a commonality of the patterns of stress distribution in an undisturbed rock mass. The area and maximum depth for applying certain geotechnologies in the framework of geomechanical models of the geomedium are established.

In focus is the methodology of the support design for a tunnel in disseminated ore mining in Zapolyarny Mine, Transpolar Division, Norilsk Nickel. The calculation of the rock bolting parameters in the zone of influence of stoping is exemplified.

The article sets methodological basis for selecting support for preparatory drives in copper–nickel ore mining by Transpolar Division of Norilsk Nickel. The authors present a case study of selecting support for preparatory drive in the influence zone of top-down multi-slice breast stoping.

The paper reviews the state-of-the-art and prospects for the mineral and raw materials supply base of Transpolar Division of Norilsk Nickel in 2015. Basic lines of activities in the area of reproduction of the reserves in the nearest future are assessed.

The article gives an account of process designs accepted and introduced in mines at Norilsk-1, Talnakh and Oktyabrsky deposits and describes new promising patented mining methods successively trialed at a commercial scale or proposed for industrial testing.

The article focuses on the current situation and challenges of the mineral and raw materials supply in Russian Federation.

By numerical calculations safe and effective excavation of flat ore deposits was designed. The excavation is performed under conditions of advancing the front of breakage heading by the system of sublevel (level) caving and combined technology of caving and stowage. Laws of stress distribution in block massif were found out considering geological irregularities which influence the excavation parameters.

The options of improving ore extraction from underground thin flat and inclined ore veins using self-propelled machine complexes are discussed in terms of renovated technology application in the Karalveem gold ore field.

This paper describes the method of photo-fixing system of fracture in rock mass, for example Black River quarry, and possible calculation of a result same physic-mechanical property

The article describes the experience of backfilling mined-out spaces in the north and south ore lentils of the Southern orebody of the Makmal deposit, Kyrgyz Republic, through gaps in the open pit bottom by using noncommercial dump material. The theoretical and technological aspects of safe underground extraction of safety pillar are discussed.

With the aim at improving the stowing performance in mines of the Norilsk Nickel JSC Transpolar Branch, the consolidating stowing mixing technology has been analyzed. The paper presents analysis results, the theory and technology aspects of higher productivity of surface stowing facilities, and describes structural modification of mills. The ball load optimization regimes and the full-scale testing of them are illustrated. Based on the offered modifications, the productivity of the mills now in force in grinding stowing components has been increased by 15–20%.

Based on the date of many-years monitoring of rock mass displacement in the Octyabrsky Mine, this paper presents same examples of variations in the rock mass movement rates.

The characteristics and development prospects of backfilling in deep mines are discussed. The authors propose a new engineering solution for the long-distance pipeline transport of the high density consolidating backfills by using hydrodynamic pressure activators. This technology allows a longer transportation distance, up to 3.5 km. The pilot-full-scale test procedure for the technology is developed and proved on a test ground in Oktyabrsky Mine, Transpolar Branch of “GMK Norilsk Nickel” Joint-Stock Co.

As a result for many years monitoring of natural-technical system of Octyabrsky Mine, this paper describes the problems in terms of Siberian mines.

The paper describes the theoretical and experimental data on fracturing brittle materials with the use of plastic substances. The authors substantiate a method of calculating a fracture dimension depending on the characteristics of the plastic substance applied and the fractured material. It is recommended on the selection of impact fracturing equipment.
