6 FAQs about [Annular down-the-hole drill rig specifications]

What are DL high-pressure Annular BOPs?

Cameron's DL high-pressure annular BOPs achieve reliable performance in a shorter height and lighter weight than comparable annular BOPs.

What is a Cameron DL high-pressure annular BOP?

Cameron DL high-pressure annular BOPs allow reliable performance in a shorter height and lighter weight than comparable annular BOPs. The unique design of our DL BOP does not require wellbore assist. The annular can close on drillpipe or large tubulars without reducing operating pressure, which minimizes risk of indention or damage to casing.

What is a hole navigation system?

Epiroc's Hole Navigation System is a smart option which enables a faster set-up for each hole – you can get right down to effective, precise drilling in all weather conditions. A SmartROC rig reduces production costs by optimizing drilling and blasting. Fragmentation is improved and a smaller amount of explosives are required.

Which rigs use North Star DTH drill pipes?

Our DTH drill pipes are used worldwide with Sandvik, Atlas Copco, XCMG and many other popular brands of DTH drilling rig. For full specifications and a rig-by-rig guide to North Star DTH drill rods, please download the Mining & Construction brochure or click right away on the Specification Tables.

What is a leopard di650i drill rig?

Leopard™ DI650i is an intelligent diesel-powered, self-contained, crawler-mounted down-the-hole drill rig built for demanding high-capacity production drilling applications in surface mining and large quarry applications.

How does an annular seal work?

The annular can close on drillpipe or large tubulars without reducing operating pressure, which minimizes risk of indention or damage to casing. Closing pressure forces the operating piston and pusher plate upward to displace the solid elastomer donut and force the packer to close inward.
