Underground roads are critical to production and operational efficiency, and road maintenance is significantly challenge by the space to operate and material available to construct. It is often geotechnical anomalies and incorrect drainage that creates areas of high subsidence or instability, as well as unacceptable surface rutting. A regular Geosynthetic solution implemented can use Geogrid and Geoweb stabilisation methods with site infill material to prevent surface rutting. This also allows improved performance for thinner pavement depths, which are critical when considering operating heights available. Geotextiles can also be used to bridge subsidence created by the impacts of blasting stopes or roadways either above or below the area of concern. The construction of thin underground pavements requires key inputs from the Geofabrics Mining Technical Hub, but can lead to significant maintenance cost savings when implemented correctly.
