<b>3D Engineering Analysis for Underground Excavations</b><br><br> <i>Examine3D</i> 4.0 is a 3D boundary element program for designing and analyzing underground excavations in rock. Although the program was developed mainly for stress analysis, its data visualization tools can be applied to a wide range of 3D mining civil engineering data, such as microseismic datasets (velocity, source parameters, event density, etc.). For 2D analyses using multiple materials, plasticity, staged excavations and support, use <i>RS2</i>.
