MINEDW is a three-dimensional (3D), finite-element, groundwater flow program that was developed specifically for mining applications. MINEDW is used worldwide to design dewatering or depressurization systems, predict local and regional environmental impacts of mine dewatering, assist in the design of water-supply systems, simulate the infilling of a “pit lake” after mining ceases, and estimate pore-pressure distributions within highwalls for geotechnical design purposes. Its user friendly graphical interface with pre- and post-processing functionality provides a powerful numerical modeling environment.
MINEDW is used at more than 50 mines throughout the world for mining-related applications in diverse hydrogeologic and climatic conditions.
Developed from FEMFLOW3D, MINEDW was validated by Sandia National Laboratories in 1998.
Simulates open-pit and underground mining for dewatering design and input to slope-stability analysis;
3D graphic representations of geology, model domain, pit geometry, groundwater heads, and pore pressures;
Simulates excavation and subsequent pit-lake infilling to represent different mining schedules; and
Simulates interaction between groundwater and surface water.
