Abstract

Technological solutions of ore loss reduction in interchamber pillars at bottom levels design of Gubkin mine are developed. For the purpose of justification of these offers has been carried out: physical (with the use of equivalent materials) and mathematical (finite element method) modeling. The research results and schedules of economic borders of use of new technologies are presented. The requirement for pilot work before industrial scale use is established.
