Application Of Geomembrane In Tailings Pond

Geomembrane is also called geomembrane liner. The main types of geomembrane are HDPE geo membrane, LLDPE geomembrane, PVC geomembrane. Geomembrane is mainly used for seepage prevention and isolation in tailings ponds.Why tailings ponds must use geomembrane, the main reasons include its excellent impermeability, anti-aging performance, construction convenience and environmental protection performance ‌. Geomembrane materials have very low permeability coefficient, which can effectively prevent the penetration of tailings liquid and groundwater, thus reducing the pollution to the environment ‌. Especially, textured geomembrane can also increase the friction coefficient between geomembrane and the construction surface, so as to better solve the problem of slope seepage prevention. It can be used in harsh environments for a long time to ensure the durability of the seepage prevention effect. Although the construction of geomembrane is convenient, it is more difficult to construct in complex terrain and harsh climatic conditions. During construction, it is necessary to pay attention to material specifications and quality, laying and welding, connection treatment and terrain complexity.
