How We Protect Tunnels and Mines 1-Rock Bolts Steel rods inserted into the rock to bind layers together and prevent separation. 2-Wire Mesh Used with rock bolts to hold small rock fragments and prevent falls. 3-Shotcrete A thin layer of sprayed concrete applied to tunnel walls to strengthen and stabilize them. 4-Steel Sets / Arches Used in areas with weak rock or high stresses to provide strong support. 5-Hydraulic Props Adjustable columns used to temporarily support the roof during operations 🛡️ Why Ground Support Matters: - Protects workers and equipment - Prevents tunnel collapses and production stoppages - Reduces accidents and repair costs Choosing the right support type depends on careful assessment of rock conditions, stress levels, and mine environment. Proper ground support design is essential for the success and sustainability of underground mining.
