“…Potential consequences affecting people or infrastructure can persist long time and include modifications of the underground water flow, surface instabilities, toxic gas emission or discharge of potentially dangerous chemicals into environment. Post-mining hazard assessment and mapping methods are based on the nature of phenomena, and have as objective to identify potentially dangerous areas, determine the possible intensity of the foreseeable phenomena and predict the probability of its occurrence in observed zone (Didier et al 2008).…”

“…Often implemented in most sensitive zones, microseismic monitoring is proven to be a valuable hazard assessment tool (Kinscher et al 2017) for measurement of the failure initiation in rocks and expected ground surface instabilities such as subsidence (sudden collapse or continuous subsidence). This is especially important in the areas where risk cannot be reduced with other options such as backfilling, which is rarely used due to its high cost (Contrucci et al 2019;Contrucci et al 2011;Contrucci et al 2008;Couffin et al 2003, Didier 2008.…”

In post-mining regions with seismic hazard, timely decision making for risk management faces the challenge of quick and reliable detection and location of seismic events. As a response to the increasing density of monitoring stations, generating large volumes of seismic data, automatic, full waveform-based methods have been developed in recent years in global seismology. Such methods often cannot be directly applied to post-mining monitoring with a limited station coverage, as it is the case when temporarily networks are installed as an emergency response.In this paper we propose a new methodology that bridges this gap and enables the application of a full waveform, backprojection based method (BackTrackBB) to data of sparse network. The methodology was successfully tested on an abandoned and flooded underground coalmine in South-eastern France. Steps preceding BackTrackBB application were implemented in order to remove the coherent noise that otherwise results in numerous false detections. First results indicate that seismic activity in the study area is controlled by water level variation within former room-and-pillar mine works and fault segments (re)activation below them.

“…Considering the time interval in which mining activities took place, sometimes the urban area are affected during exploitation period and in other cases after the closure of the works. Looking on the consulted scientific contributions, Roncourt, France is one of the affected cities, a fast evolving subsidence inducing severe damages to houses in February 1999 [43], four years after the last iron mine was closed down in Lorraine [83]. The subsidence was perfectly captured by the SAR monitoring, showing the usefulness of this methods for preventive monitoring.…”

Mining activities represent one of the main causes leading to subsidence in the natural and urban environment. Sustainable urban planning and detection of potential hazards in mining areas involve the use of adequate instruments such as the continuous monitoring of land subsidence. The complexity of urban environment demands the utilization of new methods for monitoring and quantifying the effects of the mining processes. In the last decades, considering the technological developments from the remote sensing domain, the Synthetic Aperture Radar Interferometry (InSAR) techniques offer the opportunity for early detection and continuous monitoring of subsidence in mining areas, including urban centers. Considering various parameters of mining subsidence monitoring, a review of several tens of studies realized in different mining sites, based on InSAR techniques, is presented. As mining subsidence in urban areas has a direct impact on the quality of life, the review is completed with demographic indicators assessment, followed by a study case on the dynamics of the population in an urban mining area from Romania, Ocnele Mari.
