Abstract

The invention relates to a dust-suppression and rock-discharge system utilizing tailing slurry and a dust-suppression and rock-discharge method. The system comprises a classification tailing sand preparation station and a batching rock-discharge system, wherein the tailing slurry is utilized to dedust a rock-discharge field when the two systems are used for open-cast mining and rock discharge; coal ash is added to the tailing slurry to fabricate mixed slurry at an earlier stage for the purpose of reducing abrasion of the tailing slurry to a pipeline; red mud is added to the mixed slurry at a later stage to fabricate gelling mixed slurry for the purpose that the red slurry can gel mixtures discharged by a dumping machine in the drying process; raised dust due to air drying is avoided; and gaps among rocks are decreased. With the adoption of the system and the method, water resources are saved; the gaps among the rocks discharged are decreased; potential safety hazards existing in a dumping field are eliminated; requirements of land reclamation are met; ecological restoration of a mine is facilitated; tailings are taken full advantage of and not discharged to a tailing pond; and investment and land resources are saved.

Description

[0001] technical field [0002] The invention belongs to the technical field of tailings utilization, in particular to a dust suppression and rock removal system and a dust suppression and rock removal method using tailings mud. Background technique [0003] A large amount of rocks will be stripped during open-pit mining production, and the rocks need to be sent to the dump for disposal; during mineral processing production, a large amount of tailings will be generated, and the tailings need to be pumped to the tailings pond, which occupies a large area. At present, open-pit mining production often adopts the technology of dumping rocks to the dump site; reducing the footprint of tailings ponds adopts the technology of tailings utilization. [0004] During open-pit mining production, the dumper discharges rocks to the dump site: the rocks are sent to the displacement belt conveyor by the belt conveyor, and then discharged to the soil dumper by the unloading vehicle on the di...
