摘　　要：为了查清煤层底板陷落柱的水文地球化学特征,以山西某矿大巷掘进探水过程中发现的陷落柱突水为研究对象,采用常规水质分析、特征元素含量测定和三维荧光光谱分析手段,开展了太灰水、奥灰水和陷落柱水的水化学特征组分测试。结果表明,常规水质组分中pH值、总硬度、溶解性总固体、硫酸盐、钙、钴、锰、锶反映出陷落柱水与奥灰水关系更密切,其他指标数值介于太灰与奥灰之间,反映出奥灰、太灰混合水特征。陷落柱水中有机质聚集,水动力条件弱,与上下含水层水交换较弱;DOM荧光强度最高,特别是Ⅱ区和Ⅲ区荧光峰强度,太灰水和奥灰水中荧光强度相对较弱,表明陷落柱空间自成生态系统,碳源相对丰富。利用常规组分、特征元素和有机组分,可以很好地区分出陷落柱水与其他水源的水化学特征。In order to find out the hydrogeochemical characteristics of the collapsed column in the coal seam floor,the water inrush from the collapsed column found during the water exploration process of a mine in Shanxi was used as the research object.Conventional water quality analysis,determination of characteristic element content and three-dimensional fluorescence spectroscopy were used.The water chemistry characteristic component test of too grey water,Ordovician grey water and collapsed column water was carried out.The results showed that the pH value,total hardness,total dissolved solids,sulfate,calcium,cobalt,manganese,and strontium of the conventional water quality components reflect that the collapsing column water was more closely related to the Ordovician water,and the values of other indicators were between too gray and among the Ordovician ash,it reflected the characteristics of the mixed water of the Ordovician ash and the too ash.The organic matter in the collapsed column water was concentrated,the hydrodynamic conditions were weak,and the exchange with the upper and lower aquifers was weak;the fluorescence intensity of DOM was the highest,especially the fluorescence peak intensity of zoneⅡand zoneⅢ,and the fluorescence intensity of too grey water and Ordovician grey water was relatively weak,indicating the collapsed column space forms its own ecosystem with relatively rich carbon sources.Using conventional components,characteristic elements and organic components,the hydrochemical characteristics of the collapsed column water and other water sources could be well distinguished.
