摘　　要：研究区1#煤层属于深部开采,且地质构造较为发育,底板突水危险性较高,为准确地评价1#煤层底板突水危险性,采用AHP型脆弱性指数法替代传统的突水系数法。在综合分析各种资料的基础上,选取6个主控因素进行研究,引用AHP构建模型进行权重分析,利用GIS建立专题图,经过数据归一、叠加后得到脆弱性分区。运用突水系数法进行二次突水危险性评价,并将2种结果进行比较。The No.1 coal seam in the study area belongs to deep mining and the geological structure is more developed,so the risk of water inrush is higher.In order to accurately evaluate the danger of water inrush from coal seam floor,the AHP vulnerability index method is adopted to replace the traditional water inrush coefficient method.Based on a comprehensive analysis of data,six control factors were selected and a model was constructed for weight analysis by AHP,GIS was used to construct a thematic map.After normalizing and overlaying,the division is obtained.The result was compared with another which obtained by the water inrush coefficient method.

关 键 词：底板突水 主控因素 脆弱性指数法 层次分析法
