洋水矿区位于贵州省中部,是我国重要磷矿产地之一。矿区北起温泉,南抵白马洞,长20至26公里,宽6至8公里。以往根据地质构造特征及矿床开采条件等因素,将矿区划分为极乐、沙坝土、马路坪、牛赶冲、用沙坝、两岔河以及温泉、河沙坝八个矿段。化学矿山工业部门于一九六二年和一九七○年分别在马路坪矿段和用沙坝矿段建矿——开阳磷矿。温泉矿段由地方小规模开采。河沙坝矿段磷矿层大多隐伏于地下,
Ocean water mine is located in the central part of Guizhou Province, China is one of the important phosphate rock production. The mining area starts from the hot springs in the north and reaches the white horse hole in the south. It is 20 to 26 kilometers long and 6 to 8 kilometers wide. In the past, the mining area was divided into eight sections: Bliss, Shaba, Maluoping, Niushuang, Shaba, Liangchahe, Hotspring and Heshaba, according to geological structural features and ore-mining conditions. In 1962 and 1970, the Chemical Mine Industry Department set up the Kaiyang Phosphate Mine in Maluoping and Shaba respectively. Hot spring mining area by the small-scale mining. Most of the phosphate rock layers in the Hesha dam section are buried underground.
