摘　　要：针对高河煤矿开发过程中面临的底板突水安全问题,基于对其矿井地质、水文地质的条件分析和煤层底板突水规律的研究,确定了隔水层厚度、冲洗液消耗量、单位涌水量、渗透系数、岩芯采取率、断层分布、断层规模指数以及陷落柱分布8个影响因素,并对各因素进行了归一化处理;然后利用ArcGIS软件建立相应的专题图,并运用层次分析法(AHP)确定各项因素对底板突水影响的权重,对数据进行归一化处理后按照权重进行叠加,最终得到整个井田的突水脆弱性评价分区图。研究表明,突水危险性最强的区域集中在矿区北部及中部和南部部分区域,突水危险性较强的区域分布在南部部分区域及中部和北部局部区域,其他区域危险性相对较弱。评价结果对指导煤矿安全生产具有重要意义。In response to the safety problem of the floor water inrush in the development process of the Gaoha Mine,we studied the geological and hydrogeological conditions and the floor water inrush rules in the coal seam,determined eight factors(the thickness of water-blocking layer,the consumption of flushing fluid,the unit water influx,the permeability coefficient,the core recovery rate,the distribution of faults,the fault scale index,and the distribution of collapse columns),and normalized the factors.Then,we used ArcGIS software to establish the corresponding thematic map and the hierarchical analysis process(AHP)to determine the influence weights of the factors on the floor water inrush.The data were normalized and then superimposed by the weights to finally obtain the zoning map for the vulnerability evaluation of water inrush in the whole minefield.The study showed that the areas with the strongest risk of water inrush were concentrated in the northern part of the mining area and parts of the central and southern parts of the mining area;the areas with the stronger risk of water inrush were distributed in parts of the southern part and parts of the central and northern parts of the mine;the risk in other areas was relatively weak.The evaluation results were significant in guiding the safe production of coal mines.
