Water plays a crucial role in maintaining efficient mining operations. Mines are dynamic environments, constantly influenced by changing site conditions, mine plans, seasonal weather and various water-related factors. Effective and sustainable mine water management requires a deep understanding of current conditions and leveraging historical data to improve decision-making.
DHI helps mining companies adopt an integrated water management strategy for mines to run efficiently with minimal environmental impact.
Our solution includes:
Mine dewatering – Expert groundwater extraction planning for open-pit dewatering, helping to minimise water volume, time and costs, ultimately boosting mine profitability
Determining site-wide and watershed scale water balances – Development of deterministic and probabilistic mine water balances to optimise water management from the planning phase through operations and closure
Slope stability evaluation – Creation of high-resolution 3D groundwater flow models to evaluate pit groundwater inflows and pit wall depressurisation under various configurations, providing insights that enhance the reliability of critical pore pressure estimates
Mine water management optimisation – Automated forecasting and analysis to reduce water management costs by aligning dewatering programmes with mine water management from planning to production
Mine closure planning – Impact evaluation of multiple stressors and creation of frameworks for detailed planning and design to minimise mine closure impact and improve tailings stewardship
