Control of groundwater in surface mining SpringerLinkTechnology Data Sheet Mine Dewatering Groundwater Eng
The presence of groundwater in surface mining operations often creates serious problems evaluate the influence of pore water and seepage pressures on stability and to estimate the magnitude of ground water flow Based on field investigations a design can be prepared for the control of groundwater in the slope and in the pit Technology Data Sheet Mine Dewatering Examples of mine dewatering techniques at an open pit mine Open Pit Dewatering Techniques In pit pumping This is the simplest mine dewatering approach with potentially the lowest capital costs controlled rate while monitoring flow rate and drawdown of groundwater levels Pumping tests may

Test 2 Review Open Pit Haul Roads STUDY PLAY Open Pit Mining Waste is usually removed from the pit and transported to an area outside the pit limits The deposit is benched down in successive intervals A high degree of confidence must be designed into the shovel and truck fleet to ensure a steady and continuous flow of feed The underground Berkeley Mine was located on a prominent vein extending to the southeast from the main Anaconda vein system When open pit mining operations began in July near the Berkeley Mine shaft the older mine gave its name to the pit The open pit style of mining superseded underground operations because it was far more economical and much less dangerous than underground mining
