4 Good Reasons Why Diamond Drillers Need an Aquaguard

Posted by Rod McCoremick on Sep 18, 2019 11:30:00 AM

One of the most challenging ground formations for diamond drilling is fractured ground. When drilling in highly fractured or broken ground, you run the risk of hitting a void or large fracture and having your drill water escape through that fault. Similarly, in an underground drilling environment, groundwater is often unexpectedly encountered in the drill hole. Extremely high flow rates and pressures are not uncommon.

The OWL Fishing Tool:  How Low Can You Go?

Posted by Rod McCoremick on Aug 21, 2019 10:30:00 AM

While many diamond drillers enjoy fishing in their spare time, no one wants to go fishing on the job. Fishing is the process of removing down-hole equipment that has become stuck, lost, or broken off in the hole. It means that operations have ground to a stop and your productivity is being affected.

Which Core Bit to Use When Wedging?                  The Prism60

Posted by Rod McCoremick on Jun 26, 2019 11:27:00 AM

Bore hole deviation is one of those things that occur despite all the preventative measures and precautions that diamond drillers may take. Deviations may occur due to equipment that is lost and stuck in the bore hole or it may be intentional because the geologist has requested a new trajectory. A deflection wedge is one of the oldest and simplest ways to steer the bore hole. There are other choices for directional drilling and you can read about them in this blog.

Onsite Visit Results in Left-handed Coring

Posted by Rod McCoremick on Jun 12, 2019 11:00:00 AM

Our technical team in Northern Ontario had an interesting request a while ago during an onsite visit. The mining company they were visiting was a longtime customer with multiple mines. The mine was one of the largest in the world and a large player in the area. With a lot business already done, and an excellent relationship developed over 25 years, the customer would often consult with us when it came to anything to do with coring challenges. During this particular visit, they asked if we could come up with a procedure and the necessary tooling to be able to get core using unconventional drill rigs such as a jumbo drill or a bolter.

Trouble shooting Matrix Wear – ID Gauge Loss

Posted by Rod McCoremick on May 29, 2019 2:00:00 PM

It has been a while since we did a blog on matrix troubleshooting where we examine the different wear patterns on a bit crown. By looking at the wear profile, you can get clues as to why your core bit may be underperforming. There are many variables that can cause a really good core bit to underperform. It can be a change in ground conditions, drilling parameter or simply a lack of experience.
