The histogram method of locating the capacity for internal dump at open pit coal mines in the Kemerovo region

Abstract

Using the special method of mining-geometric analysis of a pit field the criteria graphical histogram dependences determining the choice of location for the container inner blades to the regime of current pit field have been built and evaluated. It has been shown that the technical and economic indicators of industrial activity coal mines are regulated simultaneously with the cutting of the pit fields on sectors when selecting location receptacle under the inner dump and the combined ranking of the significance of the calculated values of the analyzed histograms. The proposed technological solutions for working of coal deposits of sloping and steep fall, the change of developing coal mines can significantly increase the economic efficiency of the existing mines and reduce the negative effects of open coal mining on the ecology of the Kemerovo region
