Geotechnical profiling of a surface mine waste dump using 2D Wenner–Schlumberger configuration

Mapping the subsurface in slope stability analysis of disposal areas is difficult, especially the disposal layering materials that are assumed to be homogeneous instead of their real conditions. Moreover, the hoarding activities on high slope form layers based on the nature of the rock mechanics wit...
