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 co...
