Description
Technical Field
The utility model relates to a protection facility for a water inlet of a closed-reservoir tailing pond well tunnel flood drainage system, which is used for safety protection of the water inlet of the closed-reservoir tailing pond well tunnel flood drainage system and blocking of sundries.
Background
Tailings are waste residues discharged after the concentrating mill sorts useful minerals, and are mainly discharged into a tailings pond for storage through hydraulic conveying in a tailings slurry mode. The tailings pond type mainly comprises a valley type tailings pond, a mountain side tailings pond, a land-leveling type tailings pond and a river-intercepting type tailings pond. The tailing pond which is operated to the design final elevation or no longer carries out tail discharging operation should be subjected to the pond closing treatment, and no water exists in the pond under normal conditions.
The tailing pond flood drainage system is used for water return and flood drainage in the pond, controlling water level in the pond and guaranteeing the safety of the tailing dam. The types of tailing pond flood drainage systems include both closed and open type flood drainage structures such as chutes, drainage wells, drainage pipes, culverts, tunnels, etc., and open type flood drainage structures such as spillways, open channels, etc.
The closed reservoir tail ore reservoir flood drainage system is mainly used for flood drainage, so that the water inlet is fixed, and no water exists in the reservoir under normal conditions. The open flood drainage structure after the closure has no risk of falling in high altitude generally, and is not suitable for being blocked by sundries such as trees and cloth bags; but closed flood drainage structures are not, in particular, well-hole flood drainage systems. The contracted and turning parts in the closed flood drainage structure easily cause the blockage of sundries such as trees and cloth bags, and a fence is arranged at the water inlet to prevent the sundries from entering the well. In order to prevent water from being stored in the reservoir, the water inlet of the flood drainage system of the closed reservoir tailing reservoir is usually flush with the ground, and people can easily reach the water inlet. The height of the drainage well is generally more than 5m, and particularly the depth of an old vertical shaft is deeper, so that the risk of high-altitude falling is increased. In order to solve the problems, the traditional method is to directly arrange a fence at the water inlet, and once the fence is blocked, the flood discharging capacity of the flood discharging system is greatly reduced.
