Description

Technical Field

[0001] The invention belongs to the technical field of drainage systems for tailings ponds in metal and non-metal mines, and in particular relates to a drainage system for tailings ponds. Background Art

[0002] The drainage system is one of the most basic safety facilities of the tailings pond. Whether the drainage system can operate normally is directly related to the safety status of the tailings pond. The drainage well has become a commonly used water inlet structure in the tailings pond drainage system due to its advantages such as large discharge, simple plugging and convenient control of the water level in the reservoir. At present, the drainage wells in the conventional drainage system are all connected in series, and the tailings water in the reservoir directly enters the main pipeline of the drainage system through the drainage well.

[0003] In the existing series-connected drainage system, if a well is damaged or tilted, the tailings in the reservoir will directly enter the main pipeline of the drainage system, and the drainage system's flood discharge and water return functions cannot be restored in a short period of time, which can easily cause the water level in the reservoir to rise, resulting in a shorter dry beach length and a smaller safety overheight, which will affect the flood control safety of the tailings dam. Therefore, how to repair the problematic drainage system without affecting the normal operation of the tailings pond to ensure the normal production and safety of the tailings pond is a practical issue.

[0004] In view of this, the present invention is proposed. Summary of the invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a tailings pond drainage system, which can ensure that the drainage system can operate normally during the maintenance of the drainage system.

[0006] To achieve the above object, the present invention provides the following technical solutions:

[0007] A tailings pond drainage system comprises a main drainage pipeline and a drainage well. A diversion well is arranged on the main drainage pipeline. The drainage well is connected to the diversion well through a branch drainage pipeline. The diversion well at the end of the main drainage pipeline is connected to a tunnel through a vertical shaft.

[0008] Preferably, the transfer well comprises three interfaces.

[0009] Preferably, the three interfaces are respectively connected to the upstream and downstream of the main drainage pipeline and the branch drainage pipeline.

[0010] Preferably, the angles between the three interfaces can be adjusted arbitrarily.

[0011] Preferably, the diversion well located at the end of the main drainage pipeline includes two interfaces.

[0012] Preferably, the two interfaces are connected to the main drainage pipeline and the shaft respectively.

[0013] Preferably, the angle between the two interfaces can be adjusted arbitrarily.

[0014] Preferably, the diversion well is a reinforced concrete structure.

[0015] Compared with the prior art, the present invention provides a tailings pond drainage system, in which drainage wells are set on branch lines, and the branch lines are connected to the main lines through transfer wells. If a well is found to be damaged or overturned during the operation of the drainage system, measures such as blocking the corresponding branch lines are immediately taken to prevent the tailings in the reservoir from entering the main drainage line, and to provide conditions for repairing the drainage system. Temporary drainage facilities are set on the pipelines to ensure the normal operation of the tailings pond.

[0016] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, preferred embodiments are given below and described in detail with reference to the accompanying drawings. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. The components of the embodiments of the present invention generally described and shown in the drawings here can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the drawings is not intended to limit the scope of the claimed invention, but merely represents the selected embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without making creative work belong to the scope of protection of the present invention.

[0026] like Figure 1-5 As shown, an embodiment of the present invention provides a tailings pond drainage system, including a main drainage pipeline 4 and a drainage well 1, a diversion well 2 is arranged on the main drainage pipeline 4, the drainage well 1 is connected with the diversion well 2 through a branch drainage pipeline 3, and the diversion well 2 at the end of the main drainage pipeline 4 is connected with a tunnel 6 through a vertical shaft 5.

[0027] The present invention provides convenience for the maintenance of the drainage well 1 by arranging the drainage well 1 on the branch line to avoid the influence of the drainage well 1 damage on the main line. The invention avoids the influence of the maintenance of the drainage well 1 on the normal use of the entire drainage system and ensures the safety of the tailings pond.

[0028] The diversion well 2 is located on the main drainage pipeline 4 and adopts a reinforced concrete structure. The diversion well 2 is divided into two interfaces 7 and three interfaces 7 according to the interface 7 conditions.

[0029] like Figure 4 As shown, the diversion well 2 with three interfaces 7 is a conventional diversion well 2, two of which are connected to the upstream and downstream of the main pipeline, and the third is connected to the branch pipe, and then connected to the drainage well 1. The angles between the interfaces 7 can be adjusted according to actual conditions.
