Client: Tom Guoth, GHD Ltd. (formerly Conestoga-Rovers & Associates) Ultimate Client: Regional Municipality of York Key Personnel: D. Kassenaar, E.J. Wexler, J. Ford, M. Takeda Earthfx developed a 3-dimensional groundwater flow model to analyze the impacts of construction dewatering for the Southeast Collector (SEC) Trunk Sewer on groundwater and stream baseflow. The work was done in support ...
Project Description The Ernest Henry Mine is a large open pit copper mine with deeper mineralization that was targeted for underground mining. A Feasibility Study (FS) was conducted to evaluate the potential for mining of the underground component by sublevel‐caving methods. The FS required the consideration of groundwater, including an evaluation of the expected inflows to the access ...
Abstract: A 3D groundwater flow model was constructed using MINEDW [1] to simulate pore pressure at the Chuquicamata open pit mine slope in Chile. Three main factors required the implementation of a 3D model for the prediction of pore pressures: (1) discrete zones of recharge in the gravel zone lead to the non-uniform ...
Abstract: The challenges of mining economically have never been greater than under current global financial conditions. The costs and efficiency of dewatering are particularly important at De Beers Canada’s Victor diamond mine in northern Ontario where: the bottom of the water-bearing carbonate country rocks is near the bottom of the planned pit, limiting the available drawdown in ...
Project Description Karowe Mine, located approximately 16 kilometers (km) southwest of the town of Letlhakane, is a diamond mine where the second largest diamond ever found on record, with a weight of 1,111 carats, was discovered. This project involved simulating mine dewatering and excavation to evaluate future dewatering requirements, as well as providing guidance for future monitoring borehole ...
The use of fertilizers in agriculture in Egypt, especially nitrogen, has increased significantly in the last decade, resulting in nonpoint contamination of the groundwater resources. This study investigated the effect of using nitrogen fertilizer on groundwater contamination with nitrate in the central southern part of the Nile Delta. NO3− concentrations in shallow groundwater were assessed ...
ABSTRACT This paper summarizes the development of a remedial system designed to hydraulically contain and ultimately reduce a plume consisting of primarily 1,1,2,2-tetrachloroethane (1,1,2,2-TeCA). The system consists of groundwater circulating wells or extraction wells located in the core of the 1,1,2,2-TeCA plume to provide active source control, combined with monitored ...
