MINING

Mining areas are typically affected by high subsidence phenomena due to excavations carried out.
Even at the sites of inactive and abandoned mines, subsidence still occurs years after activities have concluded.
 

Historical subsidence study
Historical subsidence study 
Measurement of subsidence with archive data in order to quantify ground movements that may threaten the mining infrastructure.
In inhabited areas, historical subsidence mapping can identify subsidence hotspots with danger for third parties.
 
Subsidence monitoring with updated data
Subsidence can also be measured with updated satellite data in order to monitor the ongoing changes in ground stability. Update of subsidence data every 35 days (frequency can be increased if desired).
Artificial Corner Reflectors can be installed where required to guarantee optimal density of measurement points.
