摘　　要：针对因钻孔单位涌水量数据严重不足而无法评判整个井田奥灰含水层富水性的实际情况,选取了新汶煤田良庄井田井下奥灰水文孔钻孔涌水量、影响煤层安全开采的奥灰上部马家沟组上段含水层厚度、井田内断层分维值、井田内褶皱分维值和奥灰上部峰峰组含水层深度5个影响因素,作为评价奥灰富水性的指标,采用主成分分析法从这5个因素中提取出主控影响因素并获得对应的权重,建立了富水性指数的数学模型。通过确定分区阈值,绘制了以富水性指数为依据的良庄井田奥灰富水性分区图,为煤矿的安全开采提供基础资料。For the actual situation about serious shortage of Liangzhuang coal mine borehole＇s specific capacity data,we can＇t evaluate the whole coal mine water-richness of ordovician limestone aquifer,so we select five factors including the borehole＇s water yield of ordovician limestone aquifer in mine,the aquifer thickness of upper ordovician limestone upper Majiagou group that affecting the safety of coal seam mining,fault fractal dimension value within coal mine,fold fractal dimension values within coal mine and the aquifer depth of upper ordovician limestone Fengfeng group as the index to evaluate the water-richness of ordovician limestone aquifer.we use principal component analysis to extract the main influencing factors and give the weight to these five factors,then we establish the mathematical model of the water-richness index to determine the divisional threshold values and draw out ordovician limestone water-richness divisions map of Liangzhuang coal mine to provide the basic data for the coal mine＇s safe mining.
