I 内蒙古科技大学硕士学位论文 I 摘要矿井通风是矿井安全生产的命脉。为了认真贯彻落实“安全第一,预防为主”的方针,促进煤矿安全生产和管理,提高矿井安全保障能力及抗灾能力,必须保证通风系统保持最佳运行状态,近些年,一些国有重点煤矿随着开采深度的加大,自然灾害的威胁更加的突出,有不少煤矿的***涌出量增大,原来是低***矿井的变为高***矿井或者有突出危险的矿井。矿井通风系统是整个煤炭企业生产大系统的命脉,它担负着向各个用风地点输送高质高量的新鲜空气。虽为矿井开采系统服务,但是事关整个企业生产大系统的安全生产,纵观历年来的煤矿事故,尤其是重特大事故,常常是***积聚造成***局部爆炸引起的,这些都与矿井的通风系统有着直接或间接的关系, 因此应该对煤矿的通风系统的安全可靠性进行评价。本文首先根据矿井通风系统安全可靠性评价体系建立的原则,从主要矿井通风动力及设施可靠性、通风系统环境可靠性、矿井安全监测系统可靠性、矿井通风防灾救灾系统可靠性4个方面建立了矿井通风系统安全可靠性评价体系,明确各评价指标的意义及计算方法,进行指标分级。介绍隶属函数确定的原则、隶属函数的构造方法及确定类型,详细的给出每个评价指标的隶属函数。运用插值法完善评价体系,利用插值法绘制出指标与其隶属度之间的函数曲线,当评价指标为一具体数值时,则其将对应一个相对精确的隶属度值。介绍了权重确定的基本理论及层次分析法,并提出改进的层次分析法,利用改进的层次分析法计算求出矿井通风系统安全可靠性评价体系准则层的权重及其各二级因素的权重,并给出评价结果的综合处理。通过对模糊综合评价方法在矿井通风系统安全可靠性评价中的应用的研究,说明模糊综合评价方法应用于矿井通风系统安全可靠性评价中的可行性,阐述模糊综合评价的一些基础知识,并介绍多层次的模糊综合评价以及模糊合成算子的选择情况,提出利用模糊综合评判评价一些定性评价的因素,用统计学方法确定模糊综合评价的隶属度,引入二级模糊综合评判评价矿井通风系统的安全可靠性的构想。关键词:矿井通风系统;评价指标;模糊评价;改进层次分析法;插值法内蒙古科技大学硕士学位论文 II Abstract Mine ventilation is the lifeblood of mine production safety. In order to conscientiously implement the "safety first, focus on prevention" the policy, the coal mine safety in production and management, improve the mine safety guarantee ability and anti-disaster ability, must assure ventilated system maintain the best running state and should,In recent years, some state-owned key coal mines along with the increase of mining depth, the threat of natural disasters is more prominent, there have been a number of coal mine gas emission increases, it is of low gas mines into gas or mine has prominent dangerous mines. Mine ventilationsystem, which is the lifeblood of the whole production in coal enterprise system, to each place the wind it breaks through the high quality high volume of fresh air. Are service for the mine production system, but is a matter of the whole enterprise production system of safe production, throughout the years of coal mine accidents, especially major workplace accidents, is often caused by
