The improvement of selective extraction of thick potash seams mined with room and pillar mining method

Article preview

Technological scheme of selective extraction of a complex thick potash seam on the basis of cutting machine «Bucyrus Model 25 M0» is proposed. Stable pillars’ width and room dimensions are calculated. Economical effect is also presented.

Organization of selective excavation of thick potash seams at chamber system of development

Article preview

The paper provides information on the distinctive features of the geological structure of the Starobinsky deposit's formations and the current mining methods used at Levels II and III. Two methods of selective potash mining using the "loading-unloading-dumping" technology are proposed. The economic effect at realization of recommended schemes is calculated.

Development and economic justification of the method of extraction of off-balance reserves of the Starobinskoe deposit

Article preview

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.
