These rigs only drill in circles around vertical cross sections in the stope. Before commencing production drilling it is important to consider many ore parameters. Important parameters include fragment size, drillability, and length of the hole, accuracy, orientation and spacing. Of late longhole drills have been the unit of choice for drilling.

The multiple benefits for BHP include optimised drilling − which in turn improves digging, loading and hauling − and increased machine uptime, without compromising the quality of the mined ore.
