Ground-Water Problems in Open-Pit and Underground Mines

Ground water constitutes a significant operational problem and potential hazard in open-pit and underground mining. The pressure of ground water in geologic discontinuities adversely affects the safety of height and slope angles of open-pit mines, justifying measures to reduce ground-water pressures in their vicinity. The principal hazard in underground mining and tunneling arises from

Simulations of open pit mines dewatering, their flooding, and environmental impact assessment are performed using groundwater flow models. They must take into consideration both regional groundwater conditions and the specificity of mine dewatering operations. This method has been used to a great extent in Polish opencast mines since the 1970s. However, the use of numerical models in mining

Water Management in Coal Mining Project: Case Study Phulbari

Jul 12, · Dewatering & Open Pit Mining The overlying or underlying sediment and rocks of coal seams in a coal bearing basin may contain water bearing strata (aquifer). Open pit mine development in such situation requires dewatering and depressurization of the aquifers through continuously pumping out of water to keep the mine pit dry and maintain safe working conditions.
