How to select a suitable geomembrane for mining containment

Geomembranes are extensively used in the mining industry for lining tailings, heap leach pads, mine solution, and evaporation ponds. Among polymeric geomembranes, HDPE and LLDPE are the most widely used for mining containment due to their high chemical resistance, ease of installation, and cost-effectiveness. However, process wastewaters and leachates with strongly alkaline or acidic pH, along with elevated temperatures, pose significant challenges to the long-term performance of geomembranes (Hornsey W.P. et al., 2009). Therefore, selecting the "ideal" geomembrane liner, especially for challenging mining applications, is more complex than for conventional applications.

What are the key considerations in designing reinforced soil slopes?

Reinforced soil slopes (RSS) stand as a cornerstone in modern geotechnical engineering, offering robust solutions for constructing slopes with inclinations less than 70 degrees from the horizontal. These structures are pivotal in combating erosion, facilitating vegetation growth, and ensuring the stability of steepened terrain. The general facing systems deployed in these constructions can be broadly classified into two types: soft or vegetated and hard armored systems, which may or may not include a geosynthetic face wrap. This comprehensive guide delves into the selection of geosynthetic facing options for reinforced slopes, underlining their importance and utility in various geotechnical applications.
