充填作业中一些沉淀缓慢的细颗粒(即细泥)可采用埋设电极之间的直流电。予以脱水并浓密,形成实用的充填体。脱水率及电能费用取决于所处理泥浆的物理、化学性质。爱达荷(Idaho)、科罗拉多(Colorado)及墨西哥(Mexico)等金属矿山的尾矿,经实验室试验,效果良好。关于极细的煤和煤矸石,脱水试验的结果。也是很令人鼓午的。本矿山局的报告,评述了两个北爱达荷矿山的现场试验,并描写了安德森矿(科罗拉多)及拉斯特雷斯矿(墨西哥)新近的装置,对处理方法、成本及有关矿工健康和安全方面的问题,也作了论述。
Some slow settling of fine particles (ie, fine mud) in the filling operation may use direct current between buried electrodes. Be dehydrated and dense, forming a practical filling body. Dehydration rates and energy costs depend on the physical and chemical properties of the slurry being treated. Tailings from metal mines such as Idaho, Colorado and Mexico are well tested in the laboratory. About the extremely fine coal and coal gangue, the result of dehydration test. It is also very drumming. The mine council’s report reviewed field tests of two northern Idaho mines and described recent installations at the Anderson Mine (Colorado) and the Lastest Mine (Mexico), addressing treatment methods, costs and health concerns for miners And security issues, but also made a discussion.
