Hydrological analysis using geoelectrics on nickel mine slopes

Abstract The sudden emergence of groundwater levels has become a critical issue at PT. Makmur Lestari Primatama, a company operating in the nickel industry. Rainwater seeps into the soil, dominates the groundwater levels, and thus impacting the mining slopes. We conducted a geoelectric study to determine the presence of groundwater and its impact on the mining slopes. The slope safety factors ranged from 0.301 to 0.960, categorized as unstable and therefore, unsafe. Redesigning the slopes as a preventive measure is advised.
