Optimization of Stope Structure Parameters of a Tin Mine Based on Numerical Simulation and Combined Weighting Method

采场结构参数作为采矿工艺的基础,既关系到开采的效益,又影响开采过程的安全性。为提升某锡矿开采回收率,通过数值模拟软件,对3组采场结构参数方案进行对比;提出一种基于博弈论与理想点法的综合评价体系,以模拟计算的结果为主要指标,对方案进一步地优选。结果表明,通过将模拟结果引入评价体系,在一定程度上能够使采场结构参数的优化结果更加科学合理。

As the foundation of mining technology,stope structure parameters are related to the benefits of mining and the safety of the mining process.In order to improve the recovery rate of a tin mine,the three groups of stope structure parameter schemes were compared through numerical simulation software.A comprehensive evaluation system based on game theory and ideal point method is proposed,and the result of simulation calculation is used as the main indicator to further optimize the scheme.The results show that by introducing the simulation results into the evaluation system,the optimization results of stope structure parameters can be made more scientific and reasonable to a certain extent.
