云南会泽麒麟厂硫化矿自下而上水平分层进路回采粗粒级(-30毫米)水砂充填采矿法系我院与波兰合作项目。1986年完成设计,经过近三年的施工,于1987年9月开始出矿试生产。该矿粗粒级水砂充填较之国内类似矿山有其三大新颖之处:一是充填料的制备,首次采用机械制备对水造浆的新形式;二是首次采用粗粒级水砂充填自动检测控制;三是充填料
Yunnan Huize unicorn factory sulfide ore bottom-up level stratified access road to the coarse-grained (-30 mm) water sand mining law is our hospital and Poland cooperation project. After completing the design in 1986, after nearly three years of construction, the trial production of ore was started in September 1987. Compared with similar mines in China, the coarse grain water sand filling of the mine has three novel features: one is the preparation of filling material, and the first is the new form of mechanical preparation of water slurry; the other is the first use of coarse-grained water sand filling Automatic detection and control; Third, filling material
