DRAINAGE SYSTEM FOR PROTECTION deep quarry on groundwater

摘要

The drainage system for the protection of deep groundwater from quarry relates to mining, in particular for dewatering mineral deposits developed by open pit. Improving the efficiency of drainage of the complex, the use of pressures aquifer for their advance towards the sump and efficient use of ground water extracted during drainage and filling of water is achieved by draining deep quarry upward and obliquely-upward wells, structures on each aquifer from a subterranean excavation situated outside the pit outline below the base of the lower aquifer having a bias towards the headers of Watershed ornikov underground water or diverted to the holding tank on the surface or in respective wells, or aquifer not participating in the flooded pit to recharge aquifers with appropriate mineral composition.
