The reconstruction of the fracture distribution behind or below the accessible surface of the rock blocks in a quarry is fundlamental to plan the mining activity and to improve the profit. Some 2D GPR surveys were executed with 50 MHz unshielded antennas and with medium frequency antennas (around 250 MHz) produced by two different GPR suppliers. The …
The future of mining is upon us, and it includes drone technology. The benefits that drones can provide to mining companies are numerous; they can be used to inspect machinery, improve security at mine sites, and check up on equipment. But there's one use of drones in particular that no company should be without: GPR (ground penetrating radar).

This article illustrates the experience of using GPR in areas of gold deposits at the Allah-Yun and Bolshoy Kuranah River (Yakutia, Russia). We considered the methodical base of dredge site GPR in the permafrost zone. The studies identified and mapped rocky outcrops and areas of boulder encrusting matter and also defined the geometry and areas of …
Ground Penetrating Radar Purposes. Ground penetrating radar is not limited to archeologists; it can also be used by outdoor enthusiasts who want to know what lies below the surface of their favorite fishing spot. GPR is like a form of sonar that uses electromagnetic radiation to detect hidden materials and objects underground.
