Abstract
This article presents an analysis of existing lava pillar excavation methods using selective mining implemented at the fourth potash horizon. A new method is proposed that ensures the recovery of not only economic resources but also non-commercial reserves of the fourth potash horizon. Non-commercial reserves are concentrated in the ninth sylvinite layer, which contains about 14% of the total resources of this horizon. The economic effect of the proposed mining method is up to $13 million for one mining pillar.
