Mines need to prevent damage to infrastructure, the environment and loss of life or injury due to unexpected surface movement. The mining industry has long been plagued by subsidence on actively mined areas as well as dormant and rehabilitated areas. One of the major causes of damage and injury on mines has been unnoticed or unexpected ground subsidence. Although ground measurements provide unrivalled absolute and relative accuracy point information in areas of concern, it is not realistic to take these measurements over the entire mine area. A significant proportion of the mine area of responsibility may therefore not be monitored.

Southern Mapping has created a package that comprises monthly radar measurements that will allow mines to mitigate the risk of subsidence. The dataset is provided to the client in a quick-to-load kml format map which reflects the subsidence or uplift over an area as well as a GIS layer containing the surface movement information over the monitoring period. This unique, cost effective solution will monitor the risk of subsidence to enable mine management to pro-actively quantify and manage risk of subsidence and failure.
