昆阳磷矿位于昆明 近郊的晋宁县境内,隶 属昆阳磷矿矿务局,是 我国重要的磷矿生产基地之一。矿区座落在景色宜人的滇池西南岸,有公路沿滇池东、西两岸各70公里直通昆明,公路8公里至晋宁县城,并有准轨铁路35公里与成昆线读书铺车站接轨,交通堪称方便。 矿区于1965年筹建,并由化工部化工矿山设计研究院和沈阳煤炭设计院共同完成了扩初设计,开采规模350万吨/年,四个采区同时开采,前期剥采比1.5米~3/吨,后期2.57米~3/吨。经1966年设计复查,决定先集中开采一、二采区,由化工矿山设计研究院于同年完成施工图设计,并在1973年进行了填平补齐配套设计。1979年进行在建项目清理,由上级机关、设计院和矿山等方面组成核查小组,核定一、二采区生产能力为160万吨/
Kunyang Phosphate Rock is located in the suburbs of Kunming, Jinning County, under the Kunyang Phosphate Mining Bureau, is one of China’s major phosphate production base. The mining area is located on the southwest bank of Dianchi Lake with pleasant scenery. There are 70 kilometers of roads along the east and west sides of Dianchi Lake leading to Kunming. The highway is 8 kilometers to Jinning County. There is 35 kilometers of quasi-rail railway connecting with the reading station of Chengdu-Kunming Railway Line. Convenient. The mining area was established in 1965 and was completed by the Ministry of Chemical Industry’s Chemical Mining Design and Research Institute and Shenyang Coal Mining Design Institute with an initial design capacity of 3.5 million tons / year. The four mining areas are also mined at the same time. / Ton, late 2.57 m ~ 3 / ton. After the design review in 1966, it was decided to concentrate on mining the first and second mining areas. The design and construction of chemical mine design institute completed the construction drawing design in the same year and completed the matching design in 1973. Construction projects in 1979 to clean up by the higher authorities, design institutes and mines and other aspects of the verification team to verify the first and second mining area production capacity of 1.6 million tons /
