采场结构参数优化是一个多因素,多层次,多属性相互影响的系统工程。为了充分发挥数值模拟与多种不确定性分析方法的评价优势,提出了FLAC3D-AHP-TOPSIS紧密结合的联合分析法。以内蒙玉龙矿为例,运用FLAC3D分析了应力、位移在不同采场结构参数方案下的变化规律,将模拟结果与采场生产能力作为影响采场方案的评价指标,导入AHP-TOPSIS模型计算出各方案的理想逼近度,从而确定玉龙矿主采区最优采场结构方案,最后对优选方案进行了充填模拟验证和生产实践验证,达到了生产高效安全、经济合理的目标。
Stope structure parameter optimization is a multi-factor, multi-level, multi-attribute interaction of systems engineering. In order to give full play to the advantages of numerical simulation and evaluation of many kinds of uncertainty analysis methods, a joint analysis method of FLAC3D-AHP-TOPSIS is proposed. Taking Yulong mine in Inner Mongolia as an example, the variation regularity of stress and displacement under different stope structure parameters was analyzed by using FLAC3D. The simulation results and stope production capacity were taken as the evaluation index to affect the stope scheme, and then imported into AHP-TOPSIS model The ideal approximation of each program to determine the Yulong mine main mining area optimal stope structure program, and finally filling the simulation program to verify the feasibility and production practices to achieve the production of high efficiency and safety, economic and reasonable goals.
