Engineering Physics Annotation << Back GRAPH-ANALYTICAL STUDIES OF THE MECHANISMS OF FORMATION OF THE SECONDARY DILUTION OF ORE IN THE DEVELOPMENT OF ORE VEINS, WHICH IS PLACED AT A GREAT DEPT Yu.P. GALCHENKO As the installed power of mining technologies, expanding the range of functionality of mining machines and the rapid improvement of ore benefi ciation methods tended to increase quantitative indicators of mining operations at the expense of quality. Increasingly, technological decisions are made on the basis of power equipment involved with the problems of transmission of high dilution of ore processing complex. The additional costs are compensated by productivity growth, but emerging environmental effects are not compensated by anything and accumulate over time. With increasing depth increases rapidly developing secondary dilution mined ores. The main factor determining the amount of the secondary dilution in absolute and relative terms, is the order and direction of clearing dredging. When the layer upward recess blocks the accumulation period of the secondary dilution includes not only the full time of breaking, but the release time of the mass of broken ore from the treatment space. Changing the order of clearing dredging and transfer to Ore breaking of vertical Cutting along the strike of the accumulation period of the secondary dilution is reduced by a multiple of the block to the volume of the unit prirezki. Key words: vein deposits. depth development, quality indicators, secondary dilution, the period of accumulation, the direction, clearing dredging, reduction ratio, the intensity of sewage extraction.
