Abstract: The development and intensification of surface coal mining in Kuzbass increase the impact of mining operations on the natural environment. Among the main negative results of this impact is the disturbance of the earth's surface. Significant areas at open-pit coal mines are occupied by overburden dumps.
The existing methods of reclamation of dumps in Kuzbass are mainly aimed at creating forest plantings. The creation of arable land requires significant expenses for the application of potentially fertile rocks. Taking into account further growth of open-pit coal mining, development of technological schemes for hydrofilling of the reclamation layer on waste rock dumps is an urgent task for Kuzbass. Hydrofilling of potentially fertile rocks is advisable to introduce in the first place at the mines, which use hydraulic mining of loose sediments.
The article considers the prospects of using reclamation layer hydrofilling on rock dumps at open-pit coal mines in Kuzbass. The composition and physical and mechanical properties of potentially fertile rocks are presented. The reclamation schemes for joint and selective placing of overburden rocks in the dumps are proposed.

Key words: Open pit mining dump hydrodump hydrofilling reclamation potentially fertile rocks
