WorldWide Drilling Resource

13 OCTOBER 2021 WorldWide Drilling Resource ® Sandvik Adds Reverse Circulation Sampling Capability to Leopard™ DI650i Drill Rig Sandvik Mining and Rock Solutions introduced a new reverse circulation (RC) sampling option for its Leopard DI650i down-the-hole (DTH) drill rig. The RC drilling system is fully integrated into the rig platform maximizing drill rig utiliza- tion while increasing productivity. The possibility to drill inclined holes with a boom-type drill rig such as the Leopard DI650i provides an easy and accurate ore body identification method and enables the use of RC face sampling for grade control in opencast mines. This drilling system is equipped with an industry-proven Metzke RC sampling unit optimally integrated onto the rig. The drill pipe setup is either 4-inch or 4½-inch RC pipes. If RC drilling is not needed, a quick and easy reconfiguration to perform the normal DTH drilling production cycle is a significant benefit of the Leopard DI650i.
