Geosynthetics in Mining Works Application Nonwoven Filter And Separation Geotextile

Geosynthetics have improved the economic and environmental performance of mining operations，so much so that the mining industry has become one of the largest users of geosynthetics.

To construct on this scale, which is often necessitated by marketplace price points and competition for investor support, requires substantial engineering to make mines economically feasible and environmentally sound.

Geosynthetic materials are one part of how mining companies achieve their goals.

Geosynthetic solutions for the mining industry are engineered for long-term performance in all environments and with the chemical compatibility necessary to meet the economic and environmental goals of today's mining operations. 

Solutions include:

• Polyethylene (PE) geomembranes as barriers

• Geosynthetic clay liners (GCLs) as barriers

• Soil-reinforcing geogrids

• Nonwoven filter and separation geotextiles

• Geocomposite drainage/gas venting materials

Geotextiles, with excellent hydraulic filter properties, have sufficient permeability to allow free movement of water. This will provide long-term stability of the foundation layers and ensure an extended life of the new road. Another advantage of using geotextiles in this project is the significant reduction of fill material required during construction. By reducing the amount of engineered fill required, the installation is simplified, which leads to time and cost savings.

Geosynthetic lining solutions enable steep slope (including mountaintop) developments. Pregnant solution flows more easily from heaped ore, and valuable material is not lost in seepage into soils or local waters. Onsite water is managed more efficiently, which also improves site costs, as water and wastewater management is a major cost in mining.
