摘要:
为了解决矿山尾砂储存和浓缩装置选择的问题,提出采用变权重分析法和TOPSIS相结合的综合评判标准体系,对3种浓缩方案进行优选。首先,建立了综合评判指标体系,以造价、运营成本、场地条件、尾砂性质、放砂浓度、容积有效利用率、检修清洗难易程度和工作效率作为考虑因素。由于层次分析法等常规方法确定的常权在评价各候选方案时可能会导致“状态失衡”的现象,所以依据变权重理论,适当调整各因素的权重,以保证各因素的均衡性;然后利用TOPSIS法逼近理想解的排序法,得出各方案的优越度;最后,以河北某铁矿浓密装置优选为例,提出3种方案,分别为卧式砂仓、立式砂仓和深锥浓密机,计算得出各方案的优越度分别为57.5%、72.1%和88.5%,最终的选择方案为深锥浓密机,该结果与工程实际相符合,表明该综合评判指标对尾砂浓缩装置的选择具有参考价值,为以后工程中的优选问题提供了一种科学、可靠的分析方法。
