脆弱性指数法在百色煤矿突水危险性评价中的应用

为了对煤田矿井所受突水威胁作出科学合理的评价,以广西百色煤田右江矿务局为例,在详细分析研究区水文地质特征的基础上,确定了影响矿井突水的8个主控因素,运用层次分析法在处理存在不确定因素或一些主观信息问题方面的优势并利用GIS的强大空间信息处理和分析功能,采用基于GIS的AHP型脆弱性指数法对研究区内矿井突水脆弱性进行了评价。

Application of Vulnerability Index for Predication and Assessment of Coal Water Bursting in Baise Coalfield

In order to predicate and evaluate the threat of water flood suffered by the mines in the study area, setting Youjiang bureau of mines in Baise coalfield as an example, on the basis of analyzing hydrogeological characteristics of the study area, eight main controlling factors which will influence floorwater bursting have been determined. By using AHP method, advantages in dealing with uncertain factors or subjective information, taking advantages of powerful function on the spatial information processing and analysis of GIS, the vulnerabilities of coal water bursting have been evaluated in the study area.
