Improving the quality of service as activity subsurface hardeningbase mining industry
The questions of efficiency of traditional technologies of underground mining of metallic ores. Determined that the decisive factor in the profitability of production are quality indicators: loss and dilution. Established that the qualitative characteristics of subsoil use, productivity and production capacity are equivalent to the ratio which is the basisfor full exploitation of mineral resources management. It is shown that the decrease ofdilu-tion in the modernization of traditional technologies for the extraction of ore is an important area of improving the efficiency of mining.
