Report Water management in mining: a selection of case studies

Sometimes mines experience a natural and continuous inflow of water, for example in the pit or underground tunnels, and this water needs to be removed (through pumping) so that access to the mine workings stays open. This is known as dewatering. This water is often either released into a receiving water source (if meeting the

Mine dewatering techniques. Dewatering and groundwater control is an important part of many open pit and underground mines. Effective dewatering is a pre-requisite for safe and efficient mining. Poorly controlled groundwater will waste money, slow down mining and potentially cause adverse environmental impacts. However, techniques are available to successful control groundwater.

What is Dewatering, When is It Used, and Methods

The dewatering process occurs by evaporation or pumping. Workers usually do it before excavation in order to decrease water table that can cause issues during excavation. What is dewatering. Usually, dewatering is a technique implemented on most construction sites because it helps retrieve water accumulated in trenches.
