利用排土场作为尾矿库围拦构筑物可显著降低尾矿库的基建投资和经营费用,并可大大节省占地面积。在这种情况下应采用分段平行堆置废石的办法,在堆置过程中沿尾矿库周边筑成围拦构筑物(尾矿坝-排土场),依次筑成彼此相连的一个个小尾矿库,相继填入尾矿并复垦。按照传统工艺,为了在堆置过程中用粘土堆筑尾矿库围拦构筑物,将粘土分层填筑, The use of the dump site as a tailings dam containment structure can significantly reduce the capital investment and operating costs of the tailings ponds and can greatly save floor space. In this case, the method of stacking the waste rock in parallel should be adopted. During the stacking process, a piled structure (tailings dam - dump) shall be built around the tailings pond and be successively connected with each other Small tailings reservoir, have been filled tailings and reclamation. In accordance with the traditional process, in order to piling clay tailings piled up in the process of building enclosures, the clay stratified filling,
