The management of water in mining operations is a critical concern that directly impacts safety, efficiency, and environmental sustainability. Excess water in mines resulting from natural groundwater seepage, surface water runoff, or precipitation can significantly hinder the effectiveness and safety of mining activities. Dewatering, the process of removing this water, is therefore a vital aspect of mining operations(Admin, 2024).
At its core, mine dewatering aims to remove or control groundwater, process water, and surface water inflows in mines, thus enabling uninterrupted mining activities. The process involves a combination of pumps, drainage systems, and sometimes the development of diversion channels to handle water efficiently. These systems are meticulously designed to deal with the variable water conditions specific to each mine(Mine Dewatering Solutions for Engineers, 2024).
Some commonly used dewatering methods in this case are (but not limited to) settling ponds, thickeners /Clarifiers and filter presses. Available space and release requirements can drive the choice of which method or methods to use. Monitoring and recording the quality of the release water is necessary to ensure minimal impact on the surrounding environment. Failure to comply can result in substantial fines and even mine closure(Why Dewatering Is Important in the Mining Industry, n.d.).
