煤炭坝矿区位于湖南省宁乡县韶山煤田的西北角。它是我国水大矿区之一。解放后,矿区的广大职工在和地下水长期斗争中积累了丰富的经验。在此基础上,本文对矿区水文地质条件,尤其对“地下径流集中带”的存在和主要进水方向等提出了粗浅的意见,作为今后防治矿井水害参考。一、矿区水文地质概况本区为西北高、东南低的低山丘陵区。地面标高一般为100～150米;最高193米,最低56米。水系发育,除沩水(一般流量为300米~3/秒)及其支流(流量为0.47米~3/秒)外,余者皆为季节性小溪。较大的泉水,有东部的鲤鱼坝泉及上中下洋泉(四个泉群的流量共
Coal Dam is located in the northwestern corner of Shaoshan Coalfield, Ningxiang County, Hunan Province. It is one of the largest mining areas in China. After the liberation, the vast number of mine workers have accumulated rich experience in long-term struggle with groundwater. On this basis, the paper puts forward some superficial opinions on the hydrogeological conditions in the mining area, especially the existence of “underground runoff concentration zone” and the main inflow direction of the mine, which serves as a reference for future prevention and control of mine water damage. First, mining hydrogeology Overview The area is northwest high, southeastern low hilly area. The ground elevation is generally 100 to 150 meters; the highest 193 meters, the lowest 56 meters. Water system development, except water (general flow of 300 m ~ 3 / s) and its tributaries (flow of 0.47 m ~ 3 / s), the rest are seasonal streams. Larger springs, the eastern part of the carp Yuquan and the upper and lower ocean springs (spring flow of four groups
