Logachov E. Elaboration of technology of underground mining of accompanying mineral raw material under the conditions of Kryvyj Rih basin.

The thesis is devoted to solving of the problem of working out of the effective technology of accompanying raw material mining due to adjacement to iron-ore deposit is evaluated. The figure of output parameters under the condition of working with blasting of handing ore package with implementation of inclined accepting workings are elaborated. The possibility of mining value of ore mass decrease is considered. The methodology of parameters choice of blasting operations is perfected. The methodology of mining of feasible tonnage of accompanying mineral raw material is worked out. The possibility of quality upgrade of talk schist on the stage of its processing and obtaining of low-grade astringent at dolomite raw material use is considered. The constructions of mining systems are elaborated.
