Mine

Ground subsidence due to underground coal mining threatens the safety of surface infrastructure such as buildings, roads, bridges, powerlines and telecommunication cables, and can cause environmental problems such as water pollution, cessation of stream flow, and so on. Monitoring the spatial distribution of surface deformation may be helpful for land-use planning, land reclamation, safety and establishing the extent of legal liability.

The applications of Radar Interferometry in mining:

• Extensively and continuously monitoring of land surface deformation from millimeters to meters over mine and building surfaces without any in-situ measurements
• Providing land deformation maps which enable us to detect changes in the subsidence pattern of the area of interest
• Overview of the area and the severity of the subsidence phenomenon
