majority of emissions can be found in discharged mine water. As mine water accumulates when the water level overflows the depth of an open pit surface mine or an underground mine, the water must be pumped or drained out of the mine to ensure safety and stability. Depending on the water availability and quality, it may be reused for
Water accumulation and related hazards can put workers in underground mines at risk. These hazards can cause serious injuries, and even death, to workers. Incidents can be prevented by ensuring: Pumping systems (sumps) are capable of removing excess water from the workplace.
