Abstract
Technological decisions on decrease in losses of ore in between chamber walls are considered at designing of the bottom horizons of mine of Gubkin. It is offered two variants of decrease in losses of the ore technologically compatible with each other for their simultaneous use. Results of calculation of losses of ore and economic consequences are resulted. The basic actions which are necessary for carrying out, before introduction of technological decisions in manufacture are described.
