摘　　要：为解决煤层底板突水预测预报评价难题,在煤层底板突水主控指标体系和脆弱性指数法提出的基础上,以开滦东欢坨矿北部采区煤层底板突水为研究对象,应用新提出的基于GIS的ANN型脆弱性指数法,在详细分析矿区水文地质条件和底板突水规律基础上,确定了6个影响煤层底板突水的主控因素;应用GIS强大的数据管理和空间分析功能,建立了煤层底板突水6个主控因素的子专题图和复合叠加图;应用AHP方法确定了各主控因素在突水过程中的权重贡献,建立了基于GIS的AHP型煤层底板突水脆弱性评价模型.根据计算所得的突水脆弱性指数统计直方图,分析确定了底板突水脆弱性分区阈值,最终提出煤层底板突水脆弱性区划方案.In order to solve the difficult evaluation problems on the coal floor water bursting, based on the establishment of the main controlling index system of the floor water bursting and theory of the vulnerable index method, the coal floor water bursting in the north mining area of Donghuantuo Coal Mine in Kailuan was studied. On the basis of analyzing the hydro-geological conditions and the floor water bursting rules of the coal mine, six main controlling factors that influencing floor water bursting were determined. Then, the six sub-thematic layers of each dominating factor and the overlay layer were founded using the data management and the spatial-data analysis of GIS. And through the application of AHP, the weight coefficients of each main controlling factor were determined in the process of floor water bursting, thus the type of AHP vulnerable evaluation model based on the GIS of floor water bursting was established. Furthermore, the thresholds of floor water bursting sub-zone were confirmed according to the statistic graphical analysis of the obtained water bursting vulnerable indexes through the model calculating. Finally, the project of the floor water bursting vulnerable zone was raised.
