Ground Support and Rock Mechanics
Understanding rock mass behavior is critical for safe underground mining. Rock Mass Classification Q-System Joint parameters, water, stress conditions. RMR Rock Mass Rating Strength, RQD, spacing, conditions, orientation. Support Requirements Support Elements - Rock bolts friction, resin, cable - Mesh weld mesh, chain link - Shotcrete plain, fiber-reinforced - Steel sets Support Design - Based on rock mass quality - Considers excavation span - Accounts for stress conditions Geological Observations - Joint spacing and conditions - Clay alteration zones - Fault proximity - Water inflow
