Abstract
Groundwater flow in an underground mining operation was affected by rock conditions and distributed through interconnected fractures. This study investigated underground groundwater leakage in a gold mining operation through permeability parameter. Groundwater inflow was obtained from water-balance analysis around 16.37 L/s. Since permeability tests sample was difficult to obtain, permeability value was estimated using Snow equations methods. The analysis had taken place in 4 different areas in the mine consisted of different rock mass classification zone. Rock Mass Rating (RMR) selected as rock mass classification system due to aperture parameter was incorporated in the classification system. The analysis was conducted through linear-regression analysis. The coefficient of correlation (R2) between RMR and permeability value was 0.7 generally. In conclusion, RMR may provide preliminary permeability value.
