选矿厂尾矿库是利用尾矿构筑,用来存贮尾矿浆的重要生产设施。它的管理状况关系到矿山持续生产和人民财产的安全。根据32个尾矿库的初步统计,冶金矿山尾矿库有如下特点:①库容量大。库容在1000万米~2以上的有18个,占56％。其中1亿米~3以上的5个,占16％,1亿～5000万米~3的库6个,占19％,5000～1000万米~37个,占22％。攀矿密地选矿厂马家田尾矿库库容最大,为1.86亿米~3。②坝体高。30m以上的坝有23个,占72％。其中:60m以上的高坝11个,占34％,低于30m的 Concentrator tailings reservoir is the use of tailings to build, used to store tailings slurry of the important production facilities. Its management status is related to the sustainable mine production and people’s property safety. According to the preliminary statistics of 32 tailings ponds, the tailings ponds of the metallurgical mine have the following characteristics: (1) Large storage capacity. Storage capacity of 10 million meters to 2 more than 18, accounting for 56%. Among them, 5 are from 100 million to 3 above, accounting for 16%, 6% from 100 million to 50 million m3, accounting for 19%, from 5000 to 10 million meters to 37, accounting for 22%. Mining Mida concentrator Majia Tian tailings storage capacity of the largest, 186 million meters ~ 3. ② high dam. There are 23 dam above 30m, accounting for 72%. Of which: 11 high dam above 60m, accounting for 34%, less than 30m
