Anti-seepage Function
Preventing leakage pollution of tailings: Tailings often contain harmful substances, such as heavy metal ions. Geomembranes have extremely low permeability and can effectively prevent harmful substances in tailings from permeating into the surrounding soil and groundwater, avoiding pollution to the soil and groundwater environment and protecting the surrounding ecological environment.
Reducing waste of water resources: Besides preventing the leakage of harmful substances, geomembranes can also prevent excessive water leakage in tailings ponds, thus reducing the waste of water resources and improving the utilization rate of water resources. This is even more important especially in areas where water resources are relatively scarce.
Isolation Function
Isolating tailings from the surrounding soil: Tailings are isolated from the surrounding soil to avoid direct contact between them, preventing the chemical components in tailings from having adverse effects on the physical and chemical properties of the soil and protecting the ecological functions and fertility of the soil.
Preventing the mixing of substances with different properties: During the tailings treatment process, tailings in different areas may have different physical and chemical properties. Geomembranes can isolate substances with different properties from each other, preventing them from mixing with each other, facilitating the zoned management and treatment of tailings and improving the treatment efficiency and effect.
Enhancing Stability
Enhancing the stability of tailings dams: Geomembranes have relatively high tensile strength and tear resistance. In the construction of tailings dams, laying geomembranes inside the dam body or on the surface of the dam foundation can enhance the integrity and stability of the dam body, improve the anti-sliding and anti-overturning abilities of the tailings dam and effectively prevent the occurrence of collapse and dam-break accidents of the tailings dam.
Adapting to foundation deformation: The foundation of a tailings pond may undergo uneven settlement under the long-term pressure of tailings. Geomembranes have good flexibility and the ability to adapt to deformation. They can deform accordingly with the deformation of the foundation and will not crack or lose the anti-seepage effect due to foundation settlement, thus ensuring the long-term stable operation of the tailings pond.
Construction Convenience
Fast construction speed: The laying of geomembranes is relatively simple and does not require complicated construction techniques and large mechanical equipment. The construction speed is fast, which can shorten the construction period of tailings treatment projects and improve the project progress.
Strong operability: Geomembranes can be cut and spliced according to the shape and size of the tailings pond and can adapt to various complex terrain conditions, including irregular terrains such as hillsides and valleys. They have strong operability and reduce the construction difficulty.
