Dth Hammer Drilling Introduction
Reverse Circulation is used in drilling programs for initial exploration and also for resource definition. There are two types of RC drilling. One is RC with hammer, used in medium and hard rock that can reach depths up to 800m. Rods are usually 4" and 4 ½" diameters.
The other is Air Core drilling used in softer oxide and clay ground to depths of 100m using Air Core & Vacuum Bits designed specifically for the type of ground conditions. RC Rods used for Air Core drilling are normally 3" to 3 ½". Roschen's has broad experience in the design and manufacture of Air Core Drilling equipment to suit a variety of ground conditions.
Roschen offers a complete line of premium quality reverse circulation, drill rods, in sizes from 3 1/2" to 10 3/4", and with a number of thread connections. All Reverse Circulation rods are manufactured using the most advanced technologies and specifically engineered to provide high strength, excellent wear resistance, and long life.
RC, dual wall drill rods are manufactured with an outer drill rod and an inner tube located inside the rod. When the drill rods are threaded together, the inner tubes seal together to provide a continuous route for cuttings to travel from the bit face to the surface for collection.
