Precise preparation and filling system for coarse aggregate and tailing slurry

The utility model provides an accurate preparation and filling system for coarse aggregate and tailing slurry. The system comprises a tailing slurry dense storage and metering system, a coarse aggregate metering and feeding system, a cement metering and feeding system, a concentrated water metering and feeding system, a filling slurry preparation system and an automatic control system, wherein the filling slurry preparation system and the automatic control system are respectively connected with all the systems. The system can realize accurate metering of each filling material by adopting a static metering-periodic preparation circulating process; the stirring time of the stirrer can be set at will, full stirring of filling materials is guaranteed, and high-quality preparation of filling slurry is guaranteed; the technical defects of poor filling slurry preparation quality, poor slurry pipeline conveying reliability, high filling cost and the like caused by low filling material metering precision, large errors
