文章摘要：基于淮南煤田各礦區(qū)各煤礦太原組灰?guī)r巖溶水水質(zhì)化驗(yàn)樣統(tǒng)計(jì)和分析,研究了其主要離子含量、水質(zhì)類型以及主要離子濃度和礦化度分布規(guī)律,提出了淮南煤田太原組灰?guī)r地下水補(bǔ)給、逕流條件和構(gòu)造控水特征。結(jié)果表明：淮南煤田是一個封閉~半封閉的水文地質(zhì)單元,淮南礦區(qū)太原組灰?guī)r巖溶裂隙水接受大氣降水補(bǔ)給、徑流條件較好,潘謝礦區(qū)、阜東礦區(qū)和新集礦區(qū)則總體賦存封閉較好,補(bǔ)給、逕流條件較差。通過此項(xiàng)研究,為指導(dǎo)淮南煤田水文地質(zhì)單元劃分和太原組灰?guī)r水害防治提供了依據(jù)與途徑。

Abstr：The main ion content, water types, main ion concentration and salinity distribution are studied, based on the laboratory sample statistics of karst water quality of each coalfield of Taiyuan formation limestone in Huainan area. Moreover, the groundwater recharge of Taiyuan limestone in Huainan coalfield, runoff conditions and water control features of geological structure are put forward. Research shows that Huainan coalfield is a closed and semi closed hydrogeolodical unit. The Taiyuan formation limestone karst fissure water in Huainan area can receive air precipitation supply better, and has better runoff conditions too. Although the occurrence and closure are overall better in Panxie and Fudong mining area, but their recharge and runoff conditions are poorer. Through this research, it provides the basis and ways for the guidance of the division of Huainan coalfield hydrogeological units and the water hazard control of karst fissure water in Taiyuan formation limestone.
