Abstract: At several coal open-pit mines of Kuzbass there are difficulties in mining coal reserves under the previously formed hydraulic-mine dumps that host rocks of quaternary deposits developed by means of hydraulic mining. The article defines the principles of selecting options for technical solutions for the development and move-ment of rock previously washed in the hydraulic-mine dump to a new location: safety and efficiency. The safety criterion is the physical and mechanical properties of rock mass, i.e. bearing capacity of the surface of the hydraulic-mine dump, forming its zones, which should be developed by appropriate technical means. The main factors of efficiency are defined. The adopted principles, criteria and factors have allowed us to form a methodological approach to the choice of options for technical solutions for the development and relocation of hydraulic-mine dump rocks to a new location and to provide a safe access to mineral resources by surface mining, and the use of hydraulic mechani-zation significantly contributes to reduction of the cost of hydraulic-mine dump relocation and mining of minerals which lie under the hydraulic-mine dump.
