摘　　要：为解决我国煤矿区普遍面临的煤层底板突水评价难题,以王庄矿15#煤层开采为例,在分析确定煤层底板突水主控因素及其对突水的"权重"系数基础上,应用新型的基于GIS的AHP型脆弱性指数法对王庄煤矿底板水害进行评价分析。并将脆弱性指数法与传统突水系数法评价结果进行对比分析,结果表明,脆弱性指数法得出评价结果更为符合实际。In order to solve the problem of coal seam floor water outburst assessment which is a widely spread phenomenon in this country,the case of mining in the #15 coal in Wangzhuang Coal Mine is taken as an example.In an analysis and determination of the major causes of coal seam floor water outbursts and their ＂weight＂ coefficient on such water outbursts,GIS based novel AHP vulnerable index method is applied in an analysis of the multiple major causes of coal seam floor water outburst in Wangzhuang Coal Mine.Besides,a comparison is made on the assessment results obtained from vulnerable index method and the traditional water outburst coefficient assessment method.The results indicate that the vulnerable index method leaves the assessment results truer to the reality.
