摘　　要：引江济淮工程的西淝河线路穿过潘谢矿区的西淝河采煤沉陷区(主要包括张集洼地、谢桥洼地等沉陷洼地)和港河下游的姬沟湖、西淝河下游的花家湖等天然湖泊,它是江水北送段的水量调蓄区之一。为保障西淝河线水质安全和水量充沛,根据引江济淮工程前期研究,当西淝河线取水口水质达到地表水Ⅲ类标准时,优先利用淮河干流调蓄,启用西淝河泵站直接从淮河干流抽水;当遭遇淮河干流污染团或水质不达标时,暂停从淮河干流抽水,利用西淝河采煤沉陷区所蓄清水,抽水北送。为了研究西淝河采煤沉陷区作为调蓄区的可能性,开展西淝河采煤沉陷区水环境特征分析,预测西淝河下游水质。采用一二维耦合水动力-水质数学模型,针对西淝河采煤塌陷区现状地形沉陷情景,开展不同来流条件的塌陷区水质模拟预测,对采煤沉陷区水质进行分析,为引江济淮江水北送段工程提供基础数据支撑。The Xifei River route of the Yangtze-to-Huaihe Water Diversion Project passes through the Xifei River coal mining subsidence area in the Panxie mining area(mainly including Zhangji Depression,Xieqiao Depression,and other subsidence depressions),as well as natural lakes such as Jigou Lake in the lower reaches of the Ganghe River and Huajia Lake in the lower reaches of the Xifei River,it is one of the water regulation and storage areas in the North Water Diversion Section of Yangtze River.In order to ensure the water quality safety and abundant water volume of the Xifei River line,according to the preliminary research of the Yangtze-to-Huaihe Water Diversion Project,when the water quality at the water intake of the Xifei River line reaches the Class II standard for surface water,priority will be given to using the main stream of the Huai River for regulation and storage,and the Xifei River pumping station will be used to directly pump water from the main stream of the Huai River;when encountering pollution or substandard water quality in the main stream of the Huai River,pumping water from the main stream of the Huai River will be suspended,and the water stored in the coal mining subsidence area of the Xifei River will be used to pump water northward.In order to study the possibility of using the Xifei River coal mining subsidence area as a storage area,an analysis of the water environment characteristics of the Xifei River coal mining subsidence area is conducted to predict the water quality downstream of the Xifei River.Using a onedimensional and two-dimensional coupled hydrodynamic water quality mathematical model,different inflow conditions are used to simulate and predict the water quality of the subsidence area in the Xifei River coal mining subsidence zone,and the water quality of the subsidence area is analyzed to provide basic data support for the North Water Diversion Project from the Yangtze River to the Huaihe River.
