基于AHP-Fuzzy-TOPSIS帕鲁特金矿不同中段开采方法对比优化选择

Comparison and Optimization of Mining Methods in the Different Middle Sections of Pakrut Gold Mine Based on AHP-Fuzzy-TOPSIS Method

随着井下开采不断向大埋深作业,通风、安全、排水等作业环境日益复杂,不同采矿方法的选择对矿山的可持续发展显得尤为重要。本文以帕鲁特金矿的开采技术条件为基础,针对4种采矿方法(崩落法、上向分层充填采矿法、分段空场嗣后充填法、梯段空场干式充填法),选取包括生产能力、采切比、损失率、贫化率、作业成本(含充填)、通风条件、生产组织和安全条件8个评价指标,运用AHP-Fuzzy-TOPSIS(层次分析-模糊数学-逼近理想解的排序法)分析模型,计算了2292 m、2050 m和1930 m三个较有代表性的中段的贴合度,并对结果进行了分析,与矿山实际生产情况贴合,验证了该方法的可行性。研究成果为下一步1930 m中段采矿方法的选择提供了理论依据,同时为其他矿井在不同生产阶段最优采矿方法选择提供了一定的借鉴意义。

With underground mining continues to operate at large buried depths,the operating environment such as ventilation,safety,and drainage is becoming more and more complex.The selection of different mining methods is particularly important for the sustainable development of mines.Based on the mining technical conditions of Pakrut Gold Mine,this paper selects four mining methods(caving method,upward layered filling mining method,segmented empty field subsequent filling method,and terraced empty field dry filling method)and 8 evaluation indicators(production capacity,cutting ratio,loss rate,dilution rate,operating cost,ventilation conditions,production organization,safety conditions).And then the AHP-Fuzzy-TOPSIS analysis model is used to calculate the accessible degree of three representative middle sections of 2292 m,2050 m and 1930 m,and the results are analyzed,which fits with the actual production situation of the mine and verifies the validity of the method.feasibility.It provides a theoretical basis for the selection of the mining method in the middle section of 1930 m in the next step,and also provides a certain reference for other mines to choose the optimal mining method in different production stages.
