Underground mining operations use geomembrane liners in order to control water flow and prevent contamination. n underground settings, geomembranes are used to line water storage and treatment ponds, preventing seepage and ensuring that mine water, often containing heavy metals and other pollutants, does not infiltrate surrounding soil and groundwater.
Geomembranes are employed in constructing underground water diversion systems, directing clean water away from contaminated zones and minimizing the mixing of clean and polluted water. This helps in maintaining the quality of both mine and surrounding water sources.
