介绍了多目标决策灰色关联投影法的原理及特点,以风压、等积孔、特征巷道风量、年通风电费、风机购置费等作为指标集,对云锡老厂深部开采通风系统设计可能方案进行客观分析优选,获得最佳方案.该方案实施后,通风效果明显改善,通风费用降低.应用实例表明,将该投影法应用到矿井通风系统方案优化中,其结果科学、有效、可行.%The theory and its features of the grey relation projection with multi-objective decision-making are introduced and described. Taking wind pressure, equivalent orifice, feature ventilation airflow, annual power costs for air and fan acquisition expenses as the index set, the objective analysis and optimization on the possible design scheme of deep mining ventilation system in Yunxi Laochang Mine are made to get an optimal scheme. Then, the ventilation effect is improved obviously and costs are lowered after the implementation of the scheme. The practical application shows that the pro jection method is scientific, effective and feasible in optimization of mine ventilation system.
