Purpose of the development: For reclamation in mining enterprises, where the coal mining system provides for storing 30-60% of the rock from the total coal production on the surface.

Recommended application field: Mining companies.

Advantages over analogues: Solving the problems of storage of mine rock. Reduction of emissions of toxic gases and pollution of groundwater. Use of recultivated areas for agricultural purposes. Rational use and utilization of associated nitrogen-phosphorus industrial waste and sewage.

The development stage readiness: Tested experimental exploitation order

Description of the development:
()
The composition and technological execution of the covering layer of mine rock dumps in the process of reclamation are proposed, which is not a mechanical insulating function but serves as an activator of the process of humus formation with oppression of the sulfate, iron and aluminum activity by mixing the upper layer of the mine rock with carbonate loam and the sediments of domestic and industrial effluents. This takes into account the interaction of the artificial fertile layer of various composition with underground and atmospheric waters, as well as the agrochemical potential of various components.
