Mining Erosion Control and Protection Solutions
Surface mining removes or strips surface vegetation, dirt and layers of bedrock in order to reach buried ore deposits (normally gold, silver and copper). There are various types of surface mining, such as open-pit mining, quarrying, strip mining and mountaintop removal. This process typically involves taking the top of a mountain off to reach ore deposits at depth.
Landfill mining involves sites where landfills are excavated and processed. Mining can create some environmental challenges, including mining erosion, sinkholes, soil contamination, and surface water contamination by chemicals from mining processes. Furthermore, there can be several high flow drainage channels that need to be maintained constantly to prevent excessive erosion.
Watershed Geo uses its years of experience in the industry to design and construct mining erosion control products that address the impact of mining erosion and some of the challenges that mining companies face.
HydroTurf® is an engineered revetment product designed to provide hard armoring for hydraulic structures against high velocity and shear stress with a polyethylene (PE) geomembrane backing. Unlike the other mining erosion control matting products available on the market today, HydroTurf Z and HydroTurf CS offer better levels of performance than other hard armor products. In addition, HydroTurf CS provides an impermeable geomembrane that is covered by a layer of engineered turf, and features an infill made from HydroBinder®, resulting in a reinforced high-strength concrete blend that is both versatile and hard-wearing.
VersaCap® is an engineered turf that eliminates hydraulic erosion and increases slope stabilization. Attached to a long-lasting polyethylene (PE) geomembrane backing, it reduces the infiltration of water on mining impoundments and tailing ponds. VersaCap® can be combined with HydroBinder™, a proprietary pozzolanic infill also designed and manufactured by Watershed Geo, to create a more economical hard armor solution. This infill increases the lifespan of the product, truly making VersaCap® a great economical solution for water infiltration mitigation. Furthermore, utilizing solar as a renewable energy source on a mining site is a viable option. By employing Watershed Geo’s proprietary solar array implementation with VersaCap®, there are two benefits: renewable energy is generated on top of an impermeable cap that can help close a mine while also creating beneficial re-use.
