Geotextile in mining works
The polyethylene HDPE geomembrane in the geosynthetic material is used as a barrier, the geosynthetic clay liner (GCL) is used as a barrier, the geogrid is used as a reinforcement, non-woven filtering and separating geotextiles, and geocomposite drainage/exhaust materials are used in mining operations It has long-term performance and has the chemical compatibility necessary to meet the economic and environmental goals of today's mining operations. In mining applications, geotextiles are widely used to protect geomembranes from puncture and deformation.
Geotextiles provide layer separation of particles, filtration stability in geostructures, and protection of other geosynthetics. As an isolation layer, geotextiles are used to prevent adjacent soil layers or filling materials from mixing with each other. In filtration applications, non-woven geotextiles are used to retain soil particles while allowing liquids to pass through the filter media. Together, these materials can improve the recovery of valuable materials, isolate contaminated waste, keep the site open, and make closures more effective and less costly.
Needle punched (mechanically bonded) nonwovens are strong geotextiles that can withstand harsh installation conditions and challenging construction loads. Their unique flexibility and elongation characteristics combine to provide high puncture resistance without compromising filtration performance. MTTVS® needle punched non-woven geotextile can provide very good long-term filtering effect and achieve high interface friction angle.
