Execution of the Geomembrane Lining Project at the Takab Gold Mine Tailing Dam
The execution of the geomembrane lining project at the Takab gold mine tailing dam, covering an area of approximately 32,000 square meters, was a meticulous and critical process. It demanded rigorous subgrade preparation, surface leveling, and the complete elimination of any protrusions or sharp impurities to definitively prevent any physical damage or punctures to the geomembrane liner.
Following the subgrade preparation phase, the geomembrane sheets were seamlessly joined using advanced thermal or ultrasonic welding methodologies to establish a completely continuous and impermeable barrier.
This engineered liner effectively prevents the migration of water and hazardous mineral effluents (tailings) into the surrounding environment, ensuring the absolute containment of toxic substances.
In the final stage, stringent Quality Control (QC) protocols—including
non-destructive leak location testing and comprehensive weld seam
inspections—were meticulously performed. These measures were taken to verify
the long-term operational durability of the lining system and to ensure the
project’s absolute compliance with rigorous industrial safety and environmental
protection standards.
