Abstract:

The exploitation of rock material usually results in a change of the in-situ force field surrounding the rock mass. Mine design is one of the major challenges when planning and operating a mine in a complex environmental context such as the Apuan Alps marble district (Italy). There could be significant risks related to the safety of both personnel and equipment. This research focuses on data collection, geo-structural interpretation and rock mechanics analysis by means of advanced remote sensing techniques (e.g. Structure for Motion methods, Terrestrial Laser Scanning, change detection analysi

Targeting marine diamondiferous deposits along the south-western Namibian coastline has involved the construction of seawall berms to advance the coastline and permit mining in previously subtidal areas. Large areas are mined out to bedrock level by the removal of overburden (sand and gravel), and after mining is complete, areas behind the seawalls fill with seawater, creating a series of coastal marine ponds that have the potential to function as saline wetlands corresponding to closed estuaries.
