safety estimation of groundwater inflow in a quarry
Ostern Quarries (1993) Ltd
Ostern Quarries (1993) Ltd , 32 It has been estimated (from a temporary take test) that a groundwater inflow of approximately 500 m 3/day reports to the Pit II area , 35 Groundwater in the pit lake is used for quarry processing and has been considered stormwater/process water...
MINING ENTERPRISES & GROUNDWATER
groundwater systems ? Mineral resource extraction leads to an inflow of ground-water to the mine or quarry and potentially major modifica-tions of groundwater flow and quality regimes, and thus to various issues requiring consideration during mine evalu-ation, development, operation and closure Groundwater...

Impact of quarry deepening on local groundwater users
The quarry depth of 78m as of 2007 caused a zone of drawdown in groundwater levels in the surrounding shale aquifer, extending ~5km to the east but a smaller distance to the west, because of good recharge from the mountainous sandstone aquifer located there Current groundwater inflow is ~200m3/day, with an electrical conductivity of 260 to ....
Geological Assessment of Quarry
Also, the pumping test is often used to estimate radius of influence; it can trigger the inflow or radius of influence Estimate of the radius of influence using analytical equation mainly independent of discharge/abstraction from the aquifer stands as a preferred choice for the prediction of radius of influence at the quarry/mine pit...

Groundwater recharge
Groundwater recharge or deep drainage or deep percolation is a hydrologic process, where water moves downward from surface water to groundwaterRecharge is the primary method through which water enters an aquiferThis process usually occurs in the vadose zone below plant roots and, is often expressed as a flux to the water table surface Groundwater recharge also encompasses water ,...

Water and Environment
The results of the analytical groundwater modelling indicate that the Penrice Quarry will become a groundwater sink post mining with water levels never recovering to the pre-mining level, due to evaporation effects assumed to be greater than predicted inflow rat The in-pit lake is...
Groundwater flow equation
the groundwater is flowing slowly (Reynolds number less than unity), and; the hydraulic conductivity (K) is an isotropic scalar Despite these large assumptions, the groundwater flow equation does a good job of representing the distribution of heads in aquifers due to a transient distribution of sources and sinks...

Inflow water quality
The potential for saline groundwater inflow at many of the proposed underground developments at Hope Bay is a concern Developments occurring within lake taliks, often within 100 to 200m vertically of the lake bottom, or below permafrost will not have the benefit of frozen ground to limit inflow...
RDA Quarry
increase in groundwater inflow is expected to be mitigated by the backfilling of overburden and beginnings of reclamation on mined out sections of the pit The backfilled overburden can "seal" the limestone stratum along the pit highwalls and reduce the rate of groundwater inflow into the pit...
