摘要: 在技术经济参数变化的情况下,主要讨论了边界品位与最终境界的关系.基于司家营露天矿生产数据,建立了盈亏平衡品位模型,并计算出不同市场价格条件下可采块段边界品位和必采块段边界品位.根据边界品位计算值,优化不同价格条件下的最终开采境界;基于某给定的边界品位,在相同的市场价格条件下进行境界优化,并比较两种方法得到的最终开采境界.结果表明,在相同的市场价格条件下,基于盈亏平衡法得到的最终境界要优于给定边界品位优化得到的最终境界.

关键词: 露天矿, 最终境界, 盈亏平衡法, 边界品位, 锥体排除法

Abstract: The relationship between the cut-off grade and the ultimate pit was analyzed under the conditions of technological and economical parameters change. Based on production data of Sijiaying open pit mine, the model of break-even grade was established to calculate the cut-off grade for needn’t to be mined and the cut-off grade for must be mined under the different conditions of market. According to the value of cut-off grade, the ultimate pit was optimized in different market context. For a preset cut-off grade, the ultimate pit was optimized at the same market context, and the ultimate pits of two methods were compared. The results indicated that under the same condition of market, the ultimate pit based on break-even method is better than that based on the preset cut-off grade.

Key words: open pit mine, ultimate pit, break-even method, cut-off grade, cone exclusive method
