为了以最小的贫化损失回采西德巴德矿的铅锌矿床,Preussag AG冶金公司试验成功了一种在各方面都能适应该矿山独特条件的新的充填采矿法—泵压充填法。使用此法可将全部尾矿注入采空区内,从而省去重选和浮选尾矿所必要的堆放场地,避免了浮选尾矿的扩散。根据该矿山应用此法的成果来看,它具有经济、保护环境等优点。所以,这种采矿方法 To recover lead-zinc deposits from the Siddebad mine with minimal depletion losses, Preussag AG Metallurgical succeeded in a new filling mining method, the pumped filling method, that is adaptable to all aspects of the mine’s unique conditions. Using this method, all the tailings can be injected into the goaf so as to save the stacking space necessary for re-selection and flotation of the tailings and avoid the proliferation of flotation tailings. According to the results of the mine using this method, it has the advantages of economy, environmental protection and so on. So, this mining method
