Abstract:

采矿方法的选择关系到矿山的经济效益和资源效益,是矿山建设和生产的核心内容。采矿方法选择是一个复杂的系统工程,具有决策多属性、确定性与不确定性共存的特点,同时传统的经验对比法具有较大的主观随意性,本文将信息论和模糊物元分析理论有机地结合,针对采矿方法的评价优选,提出了信息熵模糊物元分析法。评判优选过程中,选择如采矿成本、损失率、贫化率等决策指标;将待选择方法指标转换评判矩阵,通过信息熵模糊物元分析法得到各因素权重向量,利用熵模糊物元原理计算出各方法的相对贴近度。选取国内某矿山采矿方法为例,从安全、技术、经济3个方面综合考虑评判指标,对拟选用的3种方案进行综合评判,计算得出3种待选方法的相对贴近度分别为96.18%、81.02%、92.18%,从而确定最优方法,为矿山采矿方法的优选提供依据。该优选方法与模糊优选法有较好的一致性,且计算方法简单,评价结果直观、准确可靠,具有信息利用率高等优点。
