WASTE MANAGEMENT

Geosynthetic engineering in mine rehabilitation can achieve a cost benefit and improved environmental performance when compared to traditional engineering techniques. These solutions support mine closure and rehabilitation through applications such as tailings and water management and capping systems.

TAILINGS AND WATER MANAGEMENT

• Containing waste to protect the surrounding environment and groundwater from contamination
• Protecting lining systems to maintain the performance of waste storages and reduce leakage
• Detaining tailings and waste for treatment through evaporation or dewatering to reduce waste

CAPPING SYSTEMS

• Increasing the bearing capacity of low-strength mine waste with geotextile reinforcement layer
• Enabling the re-use of land following rehabilitation
• Minimising impact on the environment

EMBANKMENT AND SLOPE REINFORCEMENT

Rainfall erosion can cause major damage to tailings and waste embankments and cause loss of final landform profiles. Geofabrics provides a range of surface erosion control solutions designed to protect landforms, prevent high-velocity sediment movement, and support revegetation, while also:

• Securing steep slopes and unstable rock faces
• Providing a safe working environment and maintaining landform stability
• Maximising the performance and utilisation of on-site materials or fill

EROSION CONTROL AND SITE REHABILITATION

Geosynthetic erosion measures can be deployed rapidly to prevent loss of surface sediments and organic deterioration of soils, while also providing the following benefits: 

• Preventing erosion to reduce run-off into waterways
• Encouraging revegetation to protect slopes from degradation
• Supporting the restoration of natural vegetation and environment
• Minimising long-term maintenance requirements for erodible slopes
