Mining
Due to advances in electronics and software, GPR has rapidly evolved into a valuable investigative and safety tool for mapping potential loss-of-ground structures and unmapped workings within the underground mining environment. In addition, since modern GPR systems are relatively compact, they can be used without disruption of mining production. The extent of possible unstable blocks can be established more accurately and the type, length or size of support units can be designed accordingly.
Penetration can vary from a few centimeters, to tens of meters, however in the underground mining environment, where there are constraints on the physical size of the antenna that can be deployed, depths of 5-8m are typically obtained. In an opencast mine, where it is feasible to use the larger, lower frequency antennas, depths down to approximately 30m can be obtained.
