Groundradar’s new MineVue hybrid GPR system was used extensively at a number of coal mines in India to detect abandoned workings at impressive depths from both above and within mine tunnels. MineVue is an ATEX-approved, intrinsically-safe long-range GPR system designed specifically for deep void detection in mines where unshielded antennas are unsuitable. In nearly every open-pit mine where abandoned workings pose a geotechnical and safety issue, unshielded radar antennas are generally unsuitable due to the above-ground reflections from the near-by mine walls. Similarly, unshielded antennas are impossible to use underground due to the reverberations of reflections from the opposing tunnel walls. MineVue addresses these issues by using a highly effective, yet lightweight, shield, along with two advanced long-range radar systems on a single circuit board. Acquisition and data display is handled by a small Windows Mobile device, eliminating the need for bulky laptops.
