Water Control in Underground Mines – Grouting or

2012-2-19  Mine dewatering and grouting are the two most common methods of ground water control in underground mining. Both methods have advantages and limitations and their applications typically depend on a variety of factors. These factors include the hydrogeologic characteristics of the mine, the depth of the mine and mining methods, and the potential ...

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 accessibility and feature, it may be re-used for development applications on site such as framework water, filth containment or refined operations, grinding, leaching, and steam production.Since more than 70% of all pollutants from the mining industry are emitted into water, the removal of these contaminants prior to discharge is receiving significant attention. It is critical to avoid a discharge of toxic components into the environment and subsequently back to the food-chain. For the reason that local emancipation necessities are becoming more stringent, while nonconformity is being penalized more commonly and more closely. Water and waste water curing is thus becoming a most important focus of mine
