层次分析法(AHP)在江西省废弃矿井危害评价中的应用

Application of analytic hierarchical process(AHP)method in injury assessment of abandoned mining shafits in Jiangxi Province

江西省废弃矿井数量众多,为消除废弃矿井存在的安全与环境隐患,急需全面掌握现有废弃矿井危害情况。本文介绍了AHP法在废弃矿井危害评价中的应用,系统阐述了采用AHP法的评价方法与模型,为废弃矿井治理规划和防灾减灾提供科学依据。并以江西省废弃矿井为例,简述了江西省废弃矿井危害现状,进行了危害成因分析。选取了废弃矿井类型、矿井周边1 km2范围内的常住居民人数、井口稳定状态和井内安全因素等4个评价指标,对评价指标及危害等级划分进行了权重计算,评定了全省废弃矿井危害等级,有利于全面部署和推进废弃矿井安全隐患治理工作决策。

As a great number of abandoned mining shafts are existing in Jiangxi Province, an all-round keeping abreast of iniury situation of existing abandoned mining shafts is anxiously in need to eliminate the hidden safety and environment changers existing in the abandoned mining shafts. This paper introduces the appli- cation of analytic hierarchial procee（AHP） method in the injury assessment of abandoned mining shafts, and systematically explains assessment method and model by using of AHP method, providing scientific basis for harnessing of abandoned mining shafts, and prevention and reduction of disasters. Taking the a- bandoned mining shafts in Jiangxi Province as an example, the paper briefly describes the current situation of abandoned mining shafts in Jiangxi Province, and analyses the origin of injury. Choosing the types, res- ident populations in the peripheral area of 1 Km^2, wellhead stable states and within-well safety factors of abandoned mining shafts as 4 assessment indexes, a division of injury assessment indexes and injury grades is made by using of hierarchical weighted calculation and injury grades of abandoned mining shafts in the whole Province are assessed, being helpful for decision of all-round arrangement and advance for the har- nessing of hidden safety dangers.
