Geotextiles, as an important engineering material, have extensive applications in mining engineering. Mining projects often face complex geological conditions and environmental challenges. With their excellent properties of separation, filtration, drainage, and reinforcement, geotextiles can effectively address many issues in mining engineering, enhancing the safety and stability of projects.

1. Seepage Prevention and Filtration in Tailings Ponds

During mining operations, tailings ponds are critical facilities for storing tailings. Geotextiles can be used at the bottom and slopes of tailings ponds to provide seepage prevention and filtration. They prevent harmful substances in the tailings from seeping into groundwater while allowing water to pass through, avoiding excessive water accumulation in the pond and ensuring long-term stable operation.

2. Separation and Reinforcement in Stockyards

Mining stockyards are typically used to store ores or waste rocks. Geotextiles can be laid at the bottom of stockyards to separate soil from ores, preventing soil contamination and material mixing. Additionally, geotextiles enhance the overall stability of stockyards, reducing the risk of foundation settlement or landslides caused by excessive loading.

3. Optimization of Drainage Systems

Drainage is a critical issue in mining engineering. Geotextiles, with their excellent permeability, can be used in drainage ditches and layers to effectively remove accumulated water, preventing slope instability or foundation softening caused by water retention.

4. Slope Protection and Soil Erosion Control

Mining slopes are susceptible to erosion from rainwater and wind. Geotextiles can cover the slope surface, providing protection and reducing soil erosion. They also create a foundation for vegetation recovery, promoting ecological restoration.

5. Reinforcement of Roads and Temporary Facilities

Internal roads and temporary facilities in mines need to withstand frequent heavy vehicle traffic. Geotextiles can be laid in the road base to enhance load-bearing capacity, extend road service life, and reduce maintenance costs.

In summary, the application of geotextiles in mining engineering not only improves project safety and efficiency but also provides technical support for environmental protection and sustainable development. Their versatility and cost-effectiveness make them an indispensable material in mining engineering.
