Determination flooded pit mining parameters at the implementation floating wet concentrator plant

Abstract

Purpose.Establishment the main mining and haulage system parameters of the pit during development placer flooded deposits when floating wet concentrator plant is included in the technological process. Research methodology.Analytical research method was used to establish the main parameters of the pit which change as a result of the floating processing plant use. The determined influence of the mining road and ramp width of the flooded ore bench on the volume and working trench area, as well as the dependence of haulage work volume when a floating wet concentrator plant was included in the technological process a graphical research method was used. The results.The calculations for determining the working trench parameters when the floating wet concentrator plant was included in the technological process showed that the main shortage is the working trench area and volume increase. It is established that the advantages of the proposed technological scheme is a significant reduction in the haulage work volume by reducing the rock mass volume that must be moved to the processing plant, located on pit surface near the permanent trench. Scientific novelty.The dependences of changes in the permanent trench area and volume on the trench width at the inclusion floating wet concentrator plant at the mining deposit have been established. The dependence of the pit haulage work volume at the development a flooded ore bench by dredgers for two technological schemes, one of which provides for the inclusion a floating wet concentrator plant in the technological process, has been established. Practical value.The advantages and disadvantages of floating wet concentrator implementation during the mining flooded placer deposit are established. The working trench area and volume are established when the floating wet concentrator plant was included in the process during the mining pit of Motronovsky MPP. The haulage work volumes for technological schemes at the development flooded placer deposits with the presence of a floating wet concentrator plant and in its absence have been determined.
