Using 3-D structures and their virtual representation as a tool for restoring opencast mines and quarries

An important factor in the restoration studies of quarries and open-cast mines is the ability of generating final restored models of visualisation. These 3-D models are particularly useful for presenting projects, as they can greatly enhance the analysis of different alternatives. A method involving several subroutines for simulation purposes is presented in this paper. The system allows for the simulation of a variety of geological structures, both real and restored. The subroutines facilitate: (1) the automatic integration between the restoration structure and its geotechnical and morphological parameters, (2) the achievement of a uniform slope, and (3) the adjustment of the talus of the restoration structure to the relief. Graphic output in DXF and VRML formats allows for both static and dynamic optimal visualisation.
