【摘要】 矿井通风系统作为生产矿井重要的组成部分,对矿井安全生产的维护具有重要的作用。采用层次分析法,对矿井通风系统改造方案优选进行了研究,建立了通风系统改造优选指标体系,采用1—9标度法,对各项影响因素进行了权重分析,然后,在已有的矿井通风系统指标的基础之上,根据某煤矿两翼风压不平衡和通风阻力大的特点,从技术可行性、安全可靠性、经济合理性3个方面,对矿井通风系统方案优选指标进行研究,最后,对矿井通风系统改造方案优选指标进行了分级。更多还原

【Abstract】 As an important part of production mines,mine ventilation system plays an important role in the maintenance of mine safety production.The analytic hierarchy process(AHP) was used to study the optimization scheme of the mine ventilation system.The optimization index system of the ventilation system was established.The weighting analysis of each influencing factor was carried out by using the 1-9 scale method.Then,in the existing mine based on the characteristics of the ventilation system,according to the characteristics of unbalanced wind pressure and large ventilation resistance of the two wings of a coal mine,the optimal indexes of the mine ventilation system plan were studied from the aspects of technical feasibility,safety reliability and economic rationality.Finally,the classification indicators for the mine ventilation system transformation plan were graded.更多还原
