摘要 在露天矿境界优化中,优化参数的变化对最终境界会产生很大影响。其中地表约束是极其重要的优化条件,通过分析地表约束对境界优化的影响,可以确定最终境界范围的合理性,达到追求效益最大化的目标。以曙光金铜矿为例,根据最终边坡分区和边坡优化结果将矿山划分为不同区域,并根据该露天矿的矿床地质勘探资料和实际生产数据,使用克里金法对矿体品位进行估值,建立模型。在此基础上基于L-G图论法对露天矿境界进行优化,包括有地表约束和无地表约束2种情况。对优化结果进行分析和比较,结果表明:无地表约束境界比有地表约束境界多采2 867万t矿;当价格较低时,地表约束影响不明显;地表约束对Ⅳ区影响是最大的,若要开采Ⅳ区则需要使得征矿权、林权等其他费用小于1.6亿元。

Abstract: In the optimization of the open-pit boundary,the variation of the optimization parameters has a great influence on the ultimate pit limits.The surface restriction is one of the most important parameters for optimization.The effect of surface restriction on boundary optimization was analyzed to determine the rationality of the ultimate pit limits and achieve the maximum benefits.Taking Shuguang Gold-copper Mine in Hunchun as a case,the mine is divided into different regions according to the final slope division and the slope optimization result.According to the geological exploration data and actual production data of the open pit,the common Kriging method is used to estimate the grade value and the grade model is built.Then,the open-pit mine boundary with surface restrictions and no surface restrictions is optimized based on L-G graph theory.The optimization results showed that more than 28.67 million tons of ores are additionally explored in the mine with no surface restrictions boundary,compared with that of the surface restrictions,and the effect of surface restrictions is not obvious when the price is low.The surface restriction has the greatest influence on the Ⅳ zone.If the Ⅳ area is to be mined,such costs as mineral rights,forest rights and other costs are less than 160 million yuan.
