理想点法在采场结构参数优化中的应用

针对采场结构参数优选模型在评价指标趋于边缘状态时易出现“状态失衡”的现象，将变权重理论引入到采场结构参数方案评价中，并结合理想点法从经济、技术和安全3个角度选取对方案决策影响最大的9项指标建立变权重-理想点模型。在各评价指标的常权重基础上，根据各指标取值，通过变权重理论计算得到更符合各方案实际情况的变权重；然后，采用理想点法计算各方案的优劣距离，并给出最终方案的优劣排序。将该模型应用到某矿山采场结构参数方案选择中，结果表明该模型在权重计算上具有优越性，取得的优化结果更符合工程实际。

Application of Ideal Point Method in Mining Stope Structural Parameters Optimization

The model for mining stope structural parameters optimization may result in“state out of balance” phenomenon when the evaluation indexes tend to the edge state.To slove this problem，the variable weight theory was introduced into the scheme evaluation of mining stope structural parameters.Combined with the ideal point method，9 indexes which influence scheme decision mostly were selected from three angles including economy，technique and safety condition，to build the variable weight and ideal point model.In the model，the variable weight which more coincidence with actual situation of each scheme were calculated by variable weight theory based on the constant weight of each evaluation indexes.Then，the quality distance of all schemes were calculated by ideal point method and the preferential order were given.The model was used in stope structural parameters optimization of a mine and the results reflected the superiority of the model in weight calculation.The optimized result is more suitable for engineering practice.
