Dewatering is a critical process in mining operations, involving the systematic removal of groundwater or surface water to ensure a safe, stable and efficient working environment. We deliver precision-engineered dewatering solutions designed for the demanding conditions of mining and mineral extraction sites — from advanced geophysical site investigation through borehole design, wireline logging and casing installation, to submersible pump commissioning and aquifer performance testing.
Geographic Information Systems streamline sampling, analysis and decision-making across a mining area — layering topography, geology, satellite imagery and mineral/chemical data into one working model.
