为了提高矿井瓦斯抽采效果,建立了瓦斯抽采系统安全可靠性评价体系,用层次分析法对指标权重进行了计算,并通过了指标一致性检验;应用层次分析综合评价法建立了其评价模型,对大水头矿瓦斯抽采系统进行了实例评价,根据综合评价结果,判断矿井瓦斯抽采系统是否满足安全生产的要求,提出其需要整改的薄弱环节,确保矿井安全生产。
In order to improve the effect of gas drainage in coal mine, the safety and reliability evaluation system of gas drainage system was established. The index weight was calculated by AHP and passed the test of consistency of indicators. The evaluation model was established by AHP (Integrated Analytical Hierarchy Process) , Carried out a case evaluation of Dashushou Mine Gas Drainage System. According to the result of comprehensive evaluation, it is judged whether the mine gas drainage system meets the requirement of safety production, put forward the weak links which need to be rectified, and ensure the mine safety production.
