摘要
The mining method optimization in subsea deep gold mines was studied. First, an index system for subsea mining method selection was established based on technical feasibility, security status, economic benefit, and management complexity. Next, an evaluation matrix containing crisp numbers and triangular fuzzy numbers(TFNs) was constructed to describe quantitative and qualitative information simultaneously. Then, a hybrid model combining fuzzy theory and the Tomada de Decis?o Interativa Multicritério(TODIM) method was proposed. Finally, the feasibility of the proposed approach was validated by an illustrative example of selecting the optimal mining method in the Sanshandao Gold Mine(China). The robustness of this approach was demonstrated through a sensitivity analysis. The results show that the proposed hybrid TODIM method is reliable and stable for choosing the optimal mining method in subsea deep gold mines and provides references for mining method optimization in other similar undersea mines.
对海底深部金矿开采方法的优化进行研究。首先,综合考虑技术可行性、安全状况、经济效益和管理复杂性4个方面,建立海底采矿方法优化的指标体系。其次,构建一个同时包含实数和三角模糊数的评价矩阵,对定性及定量信息进行综合表征。然后,提出一种模糊理论与TODIM方法相结合的混合模型。最后,以三山岛金矿为例,对该方法的可行性进行验证,并通过灵敏度分析证实该方法具有较好的鲁棒性。结果表明,所提出的混合TODIM方法能可靠有效地用于海底深部金矿采矿方法的选择,并可为其他类似海底矿山采矿方法优化提供参考。
