MineVue project nears completion
A two-year development and testing project is drawing to a close with the imminent delivery of the first MineVue long-range radar system to the Government of India. MineVue is the longest-range shielded radar system commercially available. It is also the first low-frequency Intrinsically Safe (ATEX) radar system in the world, suitable for use in underground coal mines.
MineVue deployed in August to India, Australia, Papua New Guinea and Indonesia
Groundradar’s latest custom long-range radar system, MineVue, has been trialled extensively both above and underground at a series of Indian coal mines in Jharkand and West Bengal states. The system was able to detect abandoned coal workings at impressive depths in environments where complete radar shielding was required. 
MineVue was also tested in Papua New Guinea and Australia, where the system was used to detect voids in limestone to depths of over 40 m in cluttered surroundings where traditional low-frequency unshielded radar systems would have been unsuitable. Although limestone is generally an excellent radar environment, some limestones, particularly those with a weathered mantle of clays, can prove problematic for traditional radar equipment. MineVue is a hybrid radar system comprising of a real-time sampling impulse radar as well as a pulse-compression radar which is completely shielded, easily portable, deep penetrating, and continuously tracked by DGPS. 
A challenging laterite project in Indonesia where unshielded antennas have been unsuccessful was the site of further MineVue surveying. The results of trials were very encouraging, opening new applications for custom GPR instrumentation. 
MineVue coal radar system surveys in India
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. 
Groundradar and Utsi Electronics successfully test prototype MineVUE technology in India
Trial surveys at four underground coal mines have been conducted using a prototype long-range radar technology. The ATEX-approved instrumentation will be full shielded for deployment in environments subject to radar clutter, where long-range imaging of strata, voids and abandoned workings is required. The final system is to be delivered in Q3 2010 and will be available for use worldwide immediately thereafter.
