Open Pit Groundwater Control A range of groundwater control techniques can be used, depending on the geology and the type of mine: • Inpit pumping – used to pump from sump areas within the pit • Perimeter dewatering wells – used to intercept lateral groundwater flow into the pit and to lower groundwater levels in advance of mining • Pit slope depressurisation drains – inclined or

As the mining method is turning from open pit mining to sag by mining, the vertical height of openpit mine slope continues to increase, the slope deformation and failure mode has close relationship with regional geological structure characteristics and the rock mass structure feature, the stability is influenced largely by rock mass, joints and fissures, and blasting vibration (Qiao and Li 2004).

Open pit mining refers to mining minerals from, as the name suggests, an open pit; or may refer to any similar shallow mining operation. Open mine blasting plays a pivotal role in determining the needs of all other mining activities to come. From the loading and unloading, to transport considerations, the initial blasting will affect each and every activity that follows it. Therefore

Technology Data Sheet Mine Dewatering Groundwater is a common problem when mining, and developing a mine below groundwater level presents many challenges. Poorly controlled groundwater will have negative impacts on the safety, efficiency and economics of mining operations. If groundwater can be controlled by a planned programme of dewatering, the mine site will typically see several benefits
