Abstract:The optimization of ore drawing scheme is the basis of optimization control and intelligent management of ore drawing. In this paper, VC++ is used as a programming tool to optimize the single level ore drawing scheme. The main contents include:determine the elements of the ore drawing scheme and criteria for its optimization; construct a 3D model of drawing optimization to determine the ore drawing level and the ore drawing boundary; determine the structure parameters of the ore drawing and layout of drawpoint automatically, and establish a computational data search model of ore drawing and its slice grade, by the estimation of which to determine drawpoints and the grade distribution of slices; establish ore resource value model based on the profit of mine enterprise, with the market price, production cost and dilution index as basic input parameters to calculate the value and profit of each slice, so that to determine the best height of drawing, tonnage and cutoff grade of drawpoints under different technical and economic conditions. Based on the result of the above experiment, the optimization scheme of ore drawing is made, providing data related to ore drawing plan and management.
