Subsidence control in solution mining areas: a systematic review

For centuries, subsidence have occurred in salt mining regions. These events can be triggered by anthropogenic action, geological processes or by the association of these factors. When such problems cannot be avoided the development of control techniques (prevention, monitoring, and remediation) is required. The main objective of this study is to list the subsidence control tools presented in the literature to subside decisions in mine management. This research applies the Method Ordinatio to sorting out the most important works on subsidence in brine extraction areas. In the selected studies, 10 control techniques were identified and the main considerations about these methodologies are summarized in this paper. Additionally, all cases of subsidence in salt mining areas are presented, indicating the locality, maximum settlement rate, period of subsidence and occupation of the area. Finally, we point out which techniques we consider have the potential to be improved and used together for better control of subsidence in salt mining areas.
