A Real Challenge in Minewater Management in a High Precipitation Area: Grasberg Mine

The Grasberg Mine is the world’s largest gold mine, and is also one of the largest copper producers in the world. The mine poses a real challenge for hydrogeologists due to its size and complex hydrogeological setting, including structurally controlled groundwater flow. To assist in the development of dewatering and mine water management strategies for the remaining life of mine, a comprehensive groundwater flow model was developed by using the finite-element MINEDW code and calibrated to the available flow and water level data collected over a 20-year period of active mining.
