Abstract

The invention relates to the technical field of mine tailing filling, in particular to a tailing thickening system and a using method thereof. The tailing thickening system provided by the invention comprises a containing device, a feeding device, a stirring rake device, a driving device, a fluidized slurrying device and a discharging device; during thickening and dewatering of whole tailings, thestirring rake device of the tailing thickening system starts to run, and compression and drainage are achieved through shearing of tailing floccules; meanwhile, the mud height can be further improvedthrough stopping of operation of the stirring rake device, and the concentration efficiency and the underflow density are improved obviously; thus, when filling is not required or shutdown is required due to other reasons, the stirring rake device can be stopped, and long-time storage of tailing slurry can be achieved, so that the mining and filling balance adjustment is achieved.

Description

technical field [0001] The invention relates to the technical field of mine tailings filling, in particular to a tailings thickening system and an application method thereof. Background technique [0002] Full tailings paste filling refers to filling the downhole stope with the whole tailings discharged from the dressing plant as the aggregate, cement or other new cementitious materials as the gelling agent, and mixed and stirred to prepare a slurry with a paste flow state. The process technology is used in the mine filling method because of the advantages of less bleeding of filling slurry, less segregation, and uniform filling body. [0003] Filling concentration (mass concentration) is the key technical index of full tailings paste filling, the higher the filling concentration, the better the filling quality. In this regard, dense dehydration of the low-concentration tailings mortar discharged from the dressing plant to high-concentration or paste tailings is the core pr...
