Total-tailings paste filling and stockpiling combined treatment method based on deep-cone thickener

The invention relates to a total-tailings paste filling and stockpiling combined treatment method based on a deep-cone thickener. A combined treatment system is composed of a one-stage or multi-stage pump station, the deep-cone thickener and a two-segment horizontal stirring device. The deep-cone thickener is arranged near the multi-stage pump station. A continuous feeding and discharging mode is adopted for achieving the continuous concentration process, and the two functions of filling and tailings stockpiling are both taken into consideration. In the running process of a filling system, total tailings of a concentration plant are completely thrown into the deep-cone thickener through the one-stage or multi-stage pump station. When filling is needed, deep-cone bottom flow is pumped to the two-segment stirrer through a mortar pump and is mixed with cement, and qualified paste is prepared and flows to or is pumped to a stope. When filling is not needed, the bottom flow is pumped by a plunger pump to a tailings pond by means of the pump station, and stockpiling of paste is performed. The method can well solve the filling problem of a gob and the stockpiling problem of tailings at the same time, filling cost is greatly reduced, the strength of filling bodies is improved, discharge of the tailings is reduced to the maximum extent, and meanwhile tailings paste is discharged.
