摘要： 以张家洼铁矿-250 m中段矿体赋存条件为背景,进行了无底柱分段崩落法不同结构参数的放矿模拟试验.引入灰色局势决策理论,成功地将回收率、纯矿石回收率、岩石混入率等多目标优化问题转化为单目标优化问题.根据试验结果,采用灰色决策方法得出了张家洼铁矿-250 m中段无底柱分段崩落法的最佳结构参数为分段高度12.5 m,进路间距12 m,放矿步距4~5 m.研究结果为矿山采准设计提供了依据,研究方法为采矿工程的优化拓宽了途径.

Abstract: Taking the conditions of the medium ore body of -250 m phase in Zhangjiawa Iron Mine as background, a simulating experiment was carried out with different constructional parameters for non-pillar sublevel caving. Introducing the grey decision-making theory in the optimization of constructional parameters, the problem to transform multi-object optimization including the rates of ore recovery, undiluted ore recovery and rock drop-in into a single-object optimization was successfully solved. According to the experimental results, it was found that such optimum constructional parameters as sublevel height, drift interval and drawing pace are 12.5 m, 12 m and 4-5 m, respectively, for the non-pillar sublevel caving of the medium -250 m phase. The investigation provides not only a foundation on which the design of mining preparation is available but also a new approach to the optimization of mining engineering.
