基于AHP与加权和法的大型地下铝土矿采矿方法优选——以猫场铝矿为例
|
摘要
随着地表铝土资源的逐步减少,地下铝土资源的高效回采越来越重要,其中采矿方法的确选是关键。将大型地下铝土矿——猫场铝矿采矿方法优选视为多目标、多准则的决策问题,提出了综合考虑采矿成本等经济指标、千吨采切比等技术指标以及通风条件等安全指标的AHP与加权和法,从初选方案中确选出适合该矿山的较优的采矿方法,即在用AHP算出各准则、子准则权重的基础上,运用加权求和的原理算出各初选方案的Ci值,最后房柱采矿法以0. 478 8的Ci值确选为优秀方案。现场采场实践表明,方法高效可行,能实现猫场铝矿的安全、高效、低成本开采,达到预期设计目标。
With gradual consumption of surface ground bauxite resources,the efficient recovery of underground bauxite resources is getting more and more important.The selection of mining method is the key.The optimization of mining method for large-scale underground bauxite-Maochang aluminum mine is regarded as multi-objective and multicriteria decision-making problem.The AHP and weighted sum method was put forward comprehensively considering economic indicators such as mining cost,technical indicators such kiloton stripping ratio and ventilation conditions.The better mining method suitable for the mine was selected from the primary selection schemes.Based on the AHP,the weights of each criterion and sub-criteria were calculated.The Civalue of each selected primary scheme was calculated using the principle of weighted summation.Finally,the room and pillar method was selected as an excellent scheme with a Civalue of 0.478 8.The field practice shows that the method is efficient and feasible,and can realize the safe,efficient and low-cost mining and it can achieve the expected design goals.
