Abstract

The invention provides a tailing slurry recycling filling system. The tailing slurry recycling filling system comprises a conveying vehicle, a filter cake storage bin, a tailing slurry recycling device and a filling slurry preparing device; the conveying vehicle is used for conveying high-concentration tailing filter cakes generated in a dressing plant and formed through filter pressing to a filling station; the filter cake storage bin is used for storing the high-concentration tailings filter cakes in a concentrated mode and impacting and diluting the high-concentration tailings filter cakesthrough high-pressure water so as to output tailing slurry in a flowing mode; the tailing slurry recycling device is used for filtering and stirring the tailing slurry output by the filter cake storage bin to obtain the tailing slurry with the stable concentration; and the filling slurry preparing device is used for preparing and forming filling slurry through the tailing slurry, with the stable concentration, output by the tailing slurry recycling device and outputting the filling slurry to fill a goaf. The filter cake storage bin disperses the high-concentration tailing filter cakes throughthe high-pressure water, so that tailings and water are mixed and diluted to obtain the tailings slurry. The tailings slurry recycling device filters and stirs the tailing slurry output by the filtercake storage bin to remove coarse-particle impurities in the tailing slurry to enable the tailings and water to be mixed evenly so as to obtain the tailing slurry with the stable concentration.

Description

technical field [0001] The invention relates to the technical field of mined-out area filling, in particular to a tailings re-slurry filling system and process. Background technique [0002] At present, the filling process is mainly as follows: the tailings output from the concentrator with a concentration of about 20% is transported to the sand bin of the filling station for subsidence and dehydration, compressed air to make slurry, and the sand is released after the slurry concentration in the sand bin is stable. Add cement and additional water according to the sand ratio and concentration, and the slurry is stirred and then flowed or pumped to the goaf underground. [0003] Usually, the ore dressing plant is far away from the filling station, and the height difference is large, so it is difficult for pumping to meet the tailings transportation requirements. In addition, sometimes there is insufficient tailing sand source in the concentrator, which makes it impossible to ...
