多目标决策法在中晚期矿井通风系统优选中的应用

根据金属矿山中晚期矿井通风系统的特点，建立了矿井通风系统评价指标体系，在金属矿山中晚期矿井通风系统优化改造过程中，应用多目标决策法能够为客观、公正、快速地确定出最优方案提供数量化依据，提高了通风系统优化改造工作的效率、质量与科学决策水平，而且可指导现场通风管理人员目标明确、重点突出地进行通风系统优化改造和日常通风管理工作。

Application of Multi-object Decision Method in Optimization and Reconstruction of Pit Ventilation System during Its Mid and Late Period

Based on the characteristics of pit ventilation system during its mid and late period, the appraisement in- dicator system of the metal mine＇ s pit ventilation has been established. During the time and the course of pit ventilation system＇ s optimization and reconstruction, multi-object decision method can be used as the objective, fair and rapid way, to provide a quantifying basis to find an optimal program. The method not only can raise the efficiency and quality of work, decision-making level of optimizing and reconstructing the pit ventilation system, but also can guide the field executive personnel to optimize and reconstruct the system to deal with the daily administration work of ventilation, with a clear aim and a prominence to the key points.
