摘要
放矿方案优化是放矿优化控制和放矿管理的基础。以数字矿山软件平台和VC++为工具,进行自然崩落法放矿方案优化研究。首先确定放矿方案构成要素与放矿方案优化准则;在数字矿山软件平台上构建放矿优化三维模型,确定放矿水平及放矿边界;自动确定放矿结构参数及布置放矿点,建立放矿点和放矿分层的品位计算数据搜索模型,通过品位估值确定放矿点及放矿分层的品位分布;建立基于矿山利润的放矿资源价值模型,以金属市场价格、生产成本及贫损指标为基础输入参数,计算各放矿分层的价值和利润,得到放矿点的最佳放矿高度、担负矿量和出矿截止品位,从而确定放矿优化方案,并为放矿计划编制和管理提供数据。
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.
