In recent years, with the improvement of environmental protection regulations and the improvement
of environmental protection requirements for construction projects, the environmental protection
anti-seepage problems of mine tailings ponds have become increasingly prominent. Tailings are a type
of industrial waste, and other industrial waste dumps have similar conditions, such as power plant ash
dams, slag yards and so on.
Based on the characteristics of the tailings pond project, our company's research institute has
conducted in-depth research on the feasibility and effect of using geotextiles to reinforce the
dam. By laying HDPE geomembrane on the reinforced body slope, the influence of groundwater seepage
on the stability of the reinforced body can be prevented. Among them, the HDPE rough
geomembrane produced by our company has been widely used overall or partial in the dam building of
the reservoir area because of its high tensile strength, good anti-seepage performance, strong
deformation ability, light weight, convenient construction and low cost.
Refer to the anti-seepage requirements of the domestic waste landfill and combining the scientific
research and practice of our company's research institute, the following two technical measures are
proposed for
the mine tailings project:
1)The thickness of the HDPE geomembrane of the bottom and surrounding anti-seepage layer should be
equal to or greater than 1.5mm.
2)The tailings reservoir and slag yard that need to adopt environmental protection anti-seepage
measures should adopt single six layer HDPE geomembrane and clay or a composite anti-seepage lining
composed of bentonite anti-seepage blanket (GCL).
