Abstract
Description
Technical Field
[0001] The utility model relates to the field of metal tailings, in particular to an environmental protection management structure for a non-ferrous metal tailings pond. Background Art
[0002] During the mining process of non-ferrous metal mines, especially the concentrate beneficiation process, a large amount of tailings sand will be produced. These tailings will not only occupy a large amount of land, but the tailings themselves are also an important source of pollutants. If not treated in time, they will bring huge environmental pollution to the surrounding areas. Tailings reclamation is an important means to restore the ecological environment.
[0003] Tailings are solid particles produced by a series of mineral processing technologies. They contain large amounts of heavy metals such as copper, lead, zinc, and cadmium, often far exceeding the prescribed limits for normal soil. Tailings also often contain large amounts of metal sulfides, which easily precipitate acidic substances when exposed to air and water, becoming significant environmental pollutants. If not promptly managed, they will cause serious damage to the surrounding ecological environment.
[0004] Traditional tailings reclamation methods, such as covering with imported soil and restoring vegetation after improving the original soil, face many challenges. For example, during large-scale ecological restoration, excessive watering may lead to an increase in leachate containing heavy metals in the tailings pond, while insufficient watering may lead to a decrease in vegetation survival rate. In addition, due to the remote location of closed tailings ponds in the north, excessively high or low soil moisture can affect soil aeration and microbial activity, thereby affecting the respiration and growth of plant roots and the conduct of plant photosynthesis. Therefore, how to effectively manage tailings ponds, reduce environmental pollution, and improve vegetation survival rate has become a technical problem that needs to be solved urgently.

[0007] A pressure boosting device is provided between the water pump and the spray water pipe.

DETAILED DESCRIPTION
[0023] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Reference Figures 1-6 :
[0025] A non-ferrous metal tailings pond environmental protection management structure includes a reservoir body 1, which is used to store tailings sand. A water collection mechanism 2 and a spray mechanism 3 are provided in the reservoir body 1. A partition wall 7 is provided inside the reservoir body, and the reservoir body is divided into several independent spaces by the partition wall 7. The spray mechanism 3 is arranged inside the partition wall 7, and a green plant cultivation tank 8 is provided on the partition wall, and the nozzle 34 is controlled by a control valve 9. The water collection mechanism 2 includes several water collection holes 21 provided at the bottom of the reservoir body 1, and each water collection hole 21 is provided with a water collection pipe 22. The water collection pipe 22 is connected to a first water outlet pipe 23. The first outlet pipe 23 is connected to the first water outlet pipe 23. The water pipe 23 passes through the reservoir body 1 and is fixedly connected to the water collecting tank 24. The water collecting tank 24 is used to store the accumulated water in the reservoir body 1. The spraying mechanism 3 includes a second water outlet pipe 31 provided at the bottom of the water collecting tank 24. The second water outlet pipe 31 is connected to a water pump 32. The water pump 32 is fixedly connected to a spraying water pipe 33. The spraying water pipe 33 is provided at the bottom of the reservoir body 1 and passes through the bottom of the reservoir body 1 until it passes through the tailings ore sand. A number of connectors are provided on the spraying water pipe 33, each of which is connected to a spraying head 34. The spraying head 34 is used to spray the water in the water collecting tank 24 into the reservoir body 1.
[0026] Furthermore, in the prior art, a large amount of tailings sand mines are produced. In view of this, in the present invention, the tailings sand is concentrated in the reservoir body 1, which is the main container for storing tailings sand. For environmental protection, the reservoir body 1 is equipped with a water collection mechanism 2 and a spray mechanism 3. The water collection mechanism 2 is composed of a number of water collection holes 21 at the bottom of the reservoir body 1. A water collection pipe 22 is installed in each water collection hole 21. These water collection pipes 22 are connected to the water collection tank 24 outside the reservoir body 1 through a first water outlet pipe 23. The function of the water collection tank 24 is to collect and store the accumulated water in the reservoir body 1. The spray mechanism 3 is composed of a second water outlet pipe 31 at the bottom of the water collection tank 24, a water pump 32 and a spray water pipe 33. A second outlet pipe 31 directs water from the water collection tank 24 into a water pump 32. The water pump 32 provides power to deliver the water to the bottom of the reservoir 1 through a spray pipe 33. The spray pipe 33 extends from the bottom of the reservoir 1 to the tailings sand and is equipped with several connectors, each connected to a spray head 34. These spray heads 34 evenly spray the water from the water collection tank 24 onto the tailings sand within the reservoir 1. This not only reduces dust and environmental pollution from the tailings sand, but also helps lower the temperature within the reservoir 1 through water evaporation, promotes the consolidation of the tailings sand, and improves the stability of the reservoir 1.
[0027] Reference Figure 1-Figure 3 : A booster device 35 is provided between the water pump 32 and the spray water pipe 33.
[0028] The function of the booster device 35 is to improve the working efficiency of the water pump 32. Specifically, the water pump 32 draws water from the water collecting tank 24 and sends the water to the sprinkler head 34 at the bottom of the reservoir 1 through the sprinkler pipe 33 for spraying. In this process, the booster device 35 is installed between the water pump 32 and the sprinkler pipe 33. Its main function is to increase the water pressure so that the sprinkler head 34 can spray water into the reservoir 1 more effectively. The booster device 35 increases the speed and pressure of the water flow through compression, thereby forming a more effective spray coverage in the tailings pond, which helps to reduce dust, suppress pollution and improve the environment. Such a design not only improves the recycling efficiency of water resources, but also enhances the effect of environmental protection.
[0029] Reference Figure 4 : A detection device is provided in the storage body 1, and the detection device is used to detect the air humidity in the storage body 1. When the humidity is low, the spray mechanism 3 will be activated. The detection device includes a support column 41 provided at the bottom of the storage body 1 and passing through the tailings sand, and a humidity detector 42 is provided on the support column 41.
[0030] In the environmental protection management structure of the non-ferrous metal tailings pond, the working principle of the additional detection device is to control the activation of the spray mechanism 3 by real-time monitoring of the air humidity in the reservoir body 1. Specifically, the detection device includes a support column 41 provided at the bottom of the reservoir body 1 and passing through the tailings sand, and a humidity detector 42 is installed on the support column 41. This humidity detector 42 can sense the humidity level of the air in the reservoir body 1. When the humidity is detected to be lower than the preset threshold, the system will automatically start the spray mechanism 3. The spray mechanism 3 uses a water pump 32 to transport the water in the water collection tank 24 to the bottom of the reservoir body 1 through the spray water pipe 33, and sprays the water evenly into the reservoir body 1 through the spray head 34, thereby increasing the humidity of the air in the reservoir, preventing dust from the tailings sand, and also helping to reduce the temperature in the reservoir and promote the consolidation of the tailings sand. Such an automatic control system can ensure the stability of the environment in the tailings pond and improve the efficiency and effectiveness of environmental protection management.
[0031] Reference Figure 1 : The bottom of the storage body 1 is paved with a sand and gravel layer 5.
[0032] In the environmental protection management structure of non-ferrous metal tailings ponds, the gravel layer 5 laid at the bottom of the reservoir body 1 is an important engineering measure. Its working principle is mainly to utilize the porosity and permeability of the gravel layer 5 to enhance the drainage capacity of the bottom of the reservoir body 1. The gravel layer 5 is usually composed of sand particles and gravel of different sizes. There are a large number of gaps between these materials. When water accumulates in the reservoir or rainwater passes through the tailings sand layer, the gravel layer 5 can quickly absorb and drain this water, preventing water from accumulating at the bottom of the reservoir, thereby reducing environmental problems that may be caused by excessive water in the tailings pond, such as the generation and pollution of leachate. In addition, the gravel layer 5 also helps to filter out some suspended particles, reduce the loss of tailings sand in the tailings pond, and also provide a certain degree of protection for the stability of the tailings pond. By laying the gravel layer 5 at the bottom of the reservoir body 1, the environmental protection management effect of the tailings pond can be effectively improved and the impact on the surrounding environment can be reduced.
[0033] Reference Figure 1 : An anti-seepage layer 6 is provided below the sand and gravel layer 5.
[0034] In the environmental protection management structure of non-ferrous metal tailings ponds, the anti-seepage layer 6 added below the gravel layer 5 laid at the bottom of the reservoir body 1 is a key environmental protection measure. The main function of the anti-seepage layer 6 is to prevent water or harmful substances in the reservoir body 1 from leaking through the bottom into the surrounding soil and groundwater, thereby avoiding environmental pollution. The anti-seepage layer 6 is usually made of high-density polyethylene HDPE geomembrane or other low-permeability materials, which can effectively block the migration of water and pollutants. The working principle of the anti-seepage layer 6 is based on its extremely low permeability coefficient, which can form a closed barrier to block the penetration of water and pollutants. In the tailings pond, the anti-seepage layer 6 is usually laid below the gravel layer 5, because although the gravel layer 5 can provide certain drainage and filtration effects, it cannot completely prevent leakage. Therefore, the setting of the anti-seepage layer 6 is to provide additional safety guarantees to ensure the environmental protection management effect of the tailings pond.
[0035] A green plant cultivation layer is set on the tailings sand.
[0036] Planting a green layer on tailings sand is an ecological restoration technology. It works by creating a suitable environment for plant growth on the tailings surface, thereby restoring vegetation and stabilizing the ecosystem. This layer typically consists of a layer of soil or similar medium that provides essential nutrients, water, and rooting conditions for plants. Laying this layer on the tailings sand promotes the germination and growth of plant seeds, ultimately forming a vegetation cover, reducing soil erosion and stabilizing the reservoir slope. Furthermore, the growth of plant roots strengthens the soil structure, reducing erosion and dust emission from the tailings sand. Furthermore, the presence of vegetation helps improve the microclimate of the tailings pond, lowering the temperature in the reservoir area, increasing air humidity, and providing a habitat for wildlife, thereby promoting ecosystem diversity and self-sustaining capacity. The establishment of a green layer is a crucial component of the environmental management structure of tailings ponds. It not only helps reduce the negative impacts of tailings ponds on the environment, but also enhances the landscape and ensures the sustainable management and utilization of tailings ponds.
