Tailing heap discharge method combined with dry heaping and wet discharging
The invention discloses a tailing heap discharge method combined with dry heaping and wet discharging, and belongs to the technical field of tailing heap discharge methods. A tailing slurry conveying pipe is introduced to a tailing dry method storage yard, a centrifugal machine and a paste thickener are mounted, under the effect of centrifugal force generated by the centrifugal machine, a coarse particle part and a fine particle part in slurry are respectively separated into centrifugal machine solid residue and suspension liquid, the centrifugal machine solid residue is conveyed to a goaf by using a residue conveying vehicle, and floccules are formed and enter the paste thickener after a chemical agent solution is sufficiently mixed with the suspension liquid. Tailing slurry is separated and treated through the centrifugal machine under the condition without adding chemical agents, the separated solid residue can be directly used for goaf reclamation, the separated suspension liquid is efficiently compressed and treated through the paste thickener by adding a certain concentration of chemical agents so as to finally realize solid-liquid separation, a solid phase is piled up in the dry method storage yard, clear liquid can be recycled and reused, and thus the purposes of wet discharging and dry heaping are achieved.
