In this tutorial we will go over meshing, from the creation of a 2D mesh and how to import it to MINEDW, to the inclusion of topography, layers, and pinch-outs to different areas of interest in the model.

MINEDW
MINEDW stands out for its modelling speed, as the use of a finite elements mesh of triangular prisms allows for efficient representation of the evolution of mining topographies in time. This type of meshing allows MINEDW extreme flexibility in modeling mine plans, since, based on its vertical mesh adjustment function, new topographies and mining plans can be incorporated and modeled in a matter of days. MINEDW also allows for the incorporation of a Zone of Relaxation (ZOR), in which changes in hydraulic properties are modelled near the excavation surface of mining operations.
MINEDW has been used in more than 70 mining operations around the world, in different aspects of mining hydrogeology and water resources, such as the estimation of pore pressure distributions, the design of dewatering or depressurization systems, the prediction of local and regional environmental hydrogeological impacts, the design of water supply systems, and simulations of the filling of pit lakes after the closure of mining operations. Additionally, its graphical interface is easy to use, and its pre- and post-processing capabilities provide a powerful numerical modeling tool.
