Purpose. To increase the mining reclamation effectiveness during flat deposits open cast mining through the introduction of the technology of external and internal dumps with the common surface formation which provides the rise of reclamation lands area suitable for the agricultural use.

Methodology. We have used following theoretical and experimental methods: analysis of reclamation techniques currently in use, mathematical modeling of dump formation.

Findings. We have determined the limits of smart use of the developed dump forming method taking into account the additional increase of reclamation lands coefficient depending on the width and depth of the open cast mine. The reclamation coefficient rises by 6%, and the area under external and internal dump slopes diminishes by 39%. The external and internal dump formation flowsheet has been drawn. It includes the change of current height of the third and the fourth dump benches and allows diminishing the area under dump slopes, without involving of extra excavation equipment. The method results in reduce of mining reclamation work volume.

Originality. We have developed method of determination of the parameters of external and internal dumps with common surface and dumping flowsheets. This allows us to combine dumping and reclamation processes at all stages of deposit mining.

Practical value. Application of the suggested method and flowsheets will allow us to reduce the area under the dump slopes which is not suitable for agricultural reclamation and volumes of mining reclamation works at the cleaning-up stage of horizontal deposit mining.
