Geotextiles are permeable fabrics that are used in a variety of civil engineering and construction applications, including mining. In mining, geotextiles are used to separate, filter, reinforce, and protect different layers of soil and rock and minimize the environmental impact of mining operations.
Geotextiles in mining
One common use of geosynthetics in mining is in lining the walls and bottoms of tailings ponds to prevent seepage and erosion. Heavy duty nonwoven geotextiles can serve as a protection layer of such a lining membrane. The geotextiles or specific drainage composites can also act as a drainage layer to help remove water from the tailings pond and prevent contamination of nearby water sources.
Another use of geotextiles in mining is as a separation layer between different types of soil or rock. This can help prevent the mixing of materials during mining operations and make it easier to separate valuable minerals from waste materials.
Geosynthetics can also be used to reinforce slopes and walls in open pit mines. This can help prevent landslides and rockfalls, making mining operations safer and more efficient.
Conclusion
In short, geotextiles are used in mining to separate, filter, reinforce, and protect different layers of soil and rock, thereby ensuring safe and efficient mining operations.
