What role does shotcrete play in ground control?

Shotcrete plays a critical role in ground control by supporting and stabilizing rock structures. When applied, shotcrete creates a thin layer of concrete protective coating around rock surfaces, helping to reduce the risk of rock falls and providing immediate reinforcement to unstable geological formations. This application is vital in both underground and surface mining operations to enhance the safety and integrity of the excavation area.

The use of shotcrete also aids in controlling groundwater and preventing erosion, as it seals fractures in rock and stabilizes loose material. By improving the overall stability of the rock structures, shotcrete contributes significantly to the long-term safety and operational efficiency of mining activities.

While it can indirectly improve excavation speeds by increasing safety and reducing delays caused by rock falls, the primary function of shotcrete is not to enhance excavation speed or address environmental hazards directly, but rather to provide essential support to the mine's structural integrity.
