Geomembranes are widely used in various engineering and environmental applications, with mining engineering being one of its main application areas.

In mining engineering, geomembranes are mainly used for anti-seepage treatment of mine tailings ponds and mine pits to prevent the leakage of harmful substances from polluting the surrounding environment.

Geomembrane has the following 5 main advantages in mining engineering:

1. Anti-penetration and waterproofing: Water management is often required in mining projects. Geomembranes have good anti-penetration and waterproof properties, which can effectively prevent the leakage of groundwater and surface water and keep mining projects dry. It is the top one advantage of geomembranes used in mining.

(1) Isolate groundwater: Geomembrane has excellent waterproof performance and can effectively isolate groundwater from mining areas, prevent groundwater from being polluted, and protect the safety of groundwater resources.

(2) Prevent water and soil erosion: As an anti-penetration material, geomembrane can prevent water bodies in mining projects from leaking into the ground, avoid soil loss and erosion, and protect the ecological environment around the mine.

(3) Control drainage: During the mining process, geomembranes can be used to build drainage systems, effectively control and guide the discharge of groundwater and rainwater, and maintain the stability and safety of mining projects.

(4) Improve project efficiency: Geomembrane has the characteristics of simple construction and low cost. It can improve the construction efficiency of mining projects, shorten the project cycle, and reduce project costs.

(5) Enhance project stability: By using geomembrane as an anti-seepage layer or isolation layer in mining projects, the stability and reliability of the project can be enhanced and the risk of safety accidents in the project can be reduced.

2. Soil protection and erosion prevention: It is common for the land to be exposed in mining projects. Geomembranes can be covered on the exposed land surface to prevent the soil from being eroded by wind, water or biological erosion, and to protect soil quality and ecological environment.

(1) Prevent the erosion of exposed soil: During the mining process, the exposed soil is easily eroded by natural forces such as wind erosion and water erosion. Geomembranes can cover the soil surface to form a protective layer to effectively prevent soil erosion.

(2) Reduce water and soil erosion: Geomembrane has excellent anti-penetration properties, which can prevent rainwater and groundwater from penetrating into the soil, reduce the possibility of water and soil erosion, and protect the stability and fertility of the soil.

(3) Improve soil utilization: By laying geomembranes in mining areas, soil loss and damage can be reduced, existing soil resources can be protected, land utilization can be improved, and conditions can be provided for subsequent land reclamation and reuse.

(4) Protect the ecological environment: Mining projects may have a certain impact on the surrounding ecological environment. By using geomembranes to protect and prevent soil, the impact on the surrounding ecological environment can be reduced and the safety of vegetation and water sources can be protected.

3. Landfill coverage: Some mining projects may require landfill treatment. Geomembranes can be used as the covering layer of landfills to prevent waste leakage and contamination of groundwater, and protect the surrounding environment from pollution.

(1) Anti-penetration performance: Geomembrane has excellent anti-penetration performance, which can effectively prevent waste in landfills from leaking into groundwater and the surrounding environment, reducing the risk of groundwater pollution.

(2) Anti-seepage barrier: The laying of geomembrane can form a waterproof barrier, which can effectively prevent rainwater from penetrating into the landfill, reduce the water accumulation on the surface of the landfill and reduce the moisture content, which is beneficial to the stability and safe operation of the landfill.

(3) Soil reinforcement: Geomembrane has certain tensile strength and tear resistance, and can be used as a reinforcement material on the landfill surface to enhance the stability of the soil and prevent accidents such as landfill slope collapse and landslides. .

(4) Long-term service life: Geomembrane has good aging resistance and chemical stability, can maintain good anti-penetration performance and structural stability for a long time, and has a long service life in the landfill cover layer.

(5) Environmental protection: Effective landfill covering can reduce the emission of harmful gases in the landfill, reduce the level of environmental pollution in the landfill, and protect the ecological safety of the surrounding environment.

4. Slope stability: There may be slope stability problems during mining. Geomembranes can be used to reinforce slopes, enhance their stability, and reduce safety hazards caused by slope landslides.

(1) Prevent water and soil erosion: Geomembrane has good anti-penetration properties, which can effectively prevent rainwater and groundwater from penetrating into the slope soil, reduce the possibility of water and soil erosion, and maintain the stability of the slope soil.

(2) Improve the anti-erosion ability of slopes: Mining areas are often affected by natural factors such as rainfall, and surface runoff and erosion are prone to occur. The laying of geomembrane can form a waterproof barrier, reduce surface water erosion and erosion, and improve the erosion resistance of the slope.

(3) Reinforcement of slope structures: Geomembranes have good tensile strength and tear resistance and can be used as reinforcement materials for slope structures to enhance the overall stability of the slope and extend the service life of the slope.

(4) Reduce slope maintenance costs: By using geomembrane to reinforce slopes, slope maintenance and repair costs can be reduced, the operating costs of mining projects can be reduced, and the economic benefits of the project can be improved.

(5) Environmental protection: Reinforcing stable slopes can effectively reduce the loss of soil, rocks and other materials, prevent pollution to the surrounding environment, and protect the safety of the ecological environment.

5. Environmental protection and sustainability: As an environmentally friendly material, geomembrane has the advantage of sustainability, which can reduce the impact of mining projects on the environment and help achieve sustainable development of mining projects.

(1) Reduce pollution: As a covering material, geomembrane can effectively prevent harmful substances in landfills from leaking into groundwater and soil, reducing pollution to the surrounding environment.

(2) Resource conservation: The use of geomembrane can reduce the mining and utilization of natural resources, reduce the demand for traditional covering materials such as soil and stone, and is conducive to resource conservation and sustainable utilization.

(3) Recycling: Some geomembrane materials are recyclable and can be recycled and reused after the life of the landfill ends, reducing the need for new raw materials and reducing environmental load.

(4) Sustainable development: Through the application of geomembrane, the environmental friendliness and social responsibility of mining projects can be improved, mining enterprises can be promoted to develop in the direction of sustainable development, and the coordinated development of economy, society and environment can be achieved.
