摘要
矿井通风系统方案优化实际上是一个灰色多目标决策问题.介绍了灰色关联投影法基本原理,并通过构造灰色关联系数矩阵,确定加权向量、灰色关联投影角余弦及相关模数、计算投影值等步骤建立了综合考虑5种因素的矿井通风方案优化决策灰色关联投影模型.利用该模型确定了某钨矿井下通风系统最佳方案,该通风方案实施后,井下作业环境得到了很大的改善,通风系统测定数据表明:各项指标都达到了行业标准.
The optimization of mine ventilation system is grey multi-criteria decisions. The basic principle of grey relation projection method is introduced. The grey correlative projection model of mine ventilation system including five elements is established by the grey correlative coeflqcient matrix, the weight vectors, grey correlative projected cosine, corresponding module and the projected values. The optimum subsurface ventilation system is decided by using the grey correlative projection decisions model. After the application of the ventilation system the subsurface work atmosphere is improved greatly and the appraisement index of the ventilation meet the industry criterion.
