Abstract

Strengthening of massive with long rope barbells has distributed during development of ore deposits in sophisticated mining-geological condition. In this connection it to use rope barbells, which is able to pillar strengthen, its transfer to three-dimensional (volume) pressing from two-dimensional, reduce pillar width and reduce ore consumption has been proposed at Gubkin mine, where ore consumptions in used system of elaboration are 60% . Therefore, rope barbells can compensated excessive strain in reduced pillars.

keywords Storeyed single-stall systems of exploration, interchamber pillars, ore consumption, coefficient of sources recovery, rope barbells, economical-mathematical model, pillars strengthening, geomechanical substantiation.
