Effective underground water management in mining utilizes chemical grouting to control water ingress and stabilize the surrounding ground. These fast-reacting polyurethane or silicate-based grouts are injected into water-bearing zones to seal fractures, fill voids, and form durable barriers against water flow. Their ability to react and expand in wet conditions ensures reliable performance, even under high pressure. This approach minimizes flooding risks, enhances operational safety, and maintains the integrity of underground structures in challenging geological environments.
