In recent years, one of the most common applications of UltraGPR was the detection of cavities, usually limestone or in the open pit mines.
Although GPR has long been used for studies of detecting cavities, UltraGPR allows for both imaging cavities and abandoned tunnels, in depths greater than 40 metres. In addition to the gains of the penetration depth, ease of use allowed UltraGPR to have a lower cost for a radar survey over difficult terrain compared to traditional methods for detecting cavities geophysics, such as microgravity.
In open pit mines where unshielded antennas may not agree, Groundradar MineVue employs the most powerful armored low frequency radar in the world. MineVue successfully detected working areas abandoned more than 32 metres deep. In the last two years, it has helped deploy mines in Asia, Africa, Australia and South America.
MineVue is also the world’s number one long-range ATEX-approved GPR for operations in the coal mines.
