Reverse circulation is gaining ground as a preferred technology to collect quality samples in initial exploration, ore body development and in-pit grade control due to its cost efficiency and fast collection of dry, quality samples
Atlas Copco’s Explorac 100 is a reverse circulation drilling rig designed specifically for exploration drilling to depths of 100–200 metres. It combines a compact and robust design with the power necessary for fast collection of quality samples.
The new reverse circulation rig is designed specifically for reverse circulation drilling and other down-the-hole drilling (DTH) applications. It is suitable for exploration drilling to depths of 100–200 metres and has a lifting capacity of 10.5tons.
The Explorac 100 has a rugged and compact design, which makes it easy to move around even in rough terrain. Yet drillers will enjoy the power necessary to get more quality samples out of the ground faster.
Atlas Copco (www.atlascopco.co.uk) can provide a complete solution for reverse circulation drilling, including drilling rig, compressor, booster and drill string.
