摘　　要：为了查明刘桥二矿Ⅱ6117工作面富水区水源类别,指导防治水措施的实施,基于矿井历年水化学资料,制作水化学阴阳离子含量三线图,在此基础上分析各个含水层的矿化度、硬度、离子含量的变化特征,建立水质模型;将该工作面富水区水样与之比对,确定水源种类;最后采用模糊聚类分析方法建立评判集,进一步确定水源种类的主次关系。判断结果表明:刘桥二矿Ⅱ6117工作面富水区水同时包含有六煤砂岩裂隙水、太灰水和奥灰水,其中以六煤砂岩裂隙水和太灰水含量为主,奥灰水含量次之。In order to ascertain the water source type in the watery zone of No.II 6117 coal mining face and to guide the implementation of the water prevention and control measures,based on the historical water chemical information of the mine,a trilinear diagram of the zwitterion content was prepared.Based on the circumstances,the mineralization,hardness,ion content variation features of each aquifer were analyzed and the water quality model was established.In comparison with the water quality model and the water sample in the watery zone of the coal mining face,the water type was determined.A fuzzy clustering analysis method was applied to establish an evaluation set to further determine the main and secondary relationships of the water sources type.The judgment results showed that the water in the watery zone of No.II 6117 coal mining face of Liuqiao No.2 Mine would include sandstone water,limestone water in Taiyuan formation and Ordovician limestone water of six coal series.Among those,the sandstone water and limestone water contents in Taiyuan formation of the six coal series would be mainly and Ordovician limestone water content would be secondary.
