Dewatering
Dewatering is the process of removing water from mining sites, quarries, or construction areas to make them safe and accessible for work. Think of it like draining a bathtub - but on a much larger scale for mining operations. This is crucial because underground mines and open pits often fill with groundwater or rainwater, which needs to be removed before mining can begin or continue. Companies need specialists who understand how to manage this water removal process using pumps, wells, and drainage systems. This role is essential for keeping mining operations dry, safe, and productive.
