基于GIS的层次分析法在潘一矿突水安全性评价中的应用

The Application of Analytic Hierarchy Process Based on GIS in Safety Evaluation of Mine Water Bursting in Pan Yi Coalmine

矿井突水预测预报是目前煤矿建设和生产过程中的一大难题,本文以安徽潘一矿煤层底板突水为研究对象,基于GIS的层次分析法(AHP型)脆弱性指数法对其进行分析研究,建立影响煤层底板突水的主控指标体系,并应用GIS进行数据采集和归一化处理,建立煤层底板突水主控因素的子专题图层,然后应用AHP法确定各因素的权重比例,基于此叠加子专题图层,对潘一矿矿井突水安全性进行评价。结果表明:危险区和较危险区多位于潘一矿东南部和中东部,且突水易发生区域位置分布较集中。

Evaluation and predication of Coal floor water bursting is a difficult problem in the coal mine construction and production process,based on the coal floor water bursting in Pan Yi Coalmine,AHP vulnerability index method based on GIS was used.Firstly a main controlling factor system of coal floor water bursting has been established.Then,the sub-thematic layers of each dominating factor and the overlay layer were founded using the data management and the spatial-data analysis of GIS.Then put to use of AHP to determine weighted percentage of each main controlling factor and overlay six sub-thematic layers.on the basis,we evaluate the safety of mine water bursting in Pan Yi coalmine.The results showed that:dangerous zone is mostly located in the southeast and in the eastern and Location of water burst-prone areas are always concentrated.
