Comparing Diamond Drilling with Reverse Circulation Drilling

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

Most of our blogs focus on diamond drilling, but occasionally we will delve into topics related to geotechnical or other types of drilling. In this blog, we are going to look at reverse circulation drilling, known as RC drilling.

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.

Hero 5 Abrasive: A Bit That Lasts Longer and Cuts Consistently

Posted by Rod McCoremick on Dec 10, 2018 10:30:00 AM

In order to accomplish our corporate goal of improving drilling performance, our engineering team develops new core bits that address particular drilling challenges. Rock abrasiveness is a common challenge faced by many diamond drillers. Abrasiveness can wear down bits prematurely, regardless of the hardness of the ground.

How to Stabilize Your Core Barrel

Posted by Rod McCoremick on Nov 26, 2018 11:01:00 AM

When the geologist has given you a specific target to reach with your bore hole, many of them will make specific requests that a hole proceed in a very straight direction for a certain number of meters. A lot will be riding on your ability to get there without your bore hole deviating. Most diamond drillers know that preventing bore hole deviation is a lot easier than having to correct once it’s gone off the trajectory. One way to avoid the risk of deviation is to stabilize your core barrel before you start drilling and you do this by changing some of the equipment you usually use.

A New Guide for Diamond Drillers on Bore Hole Deviation

Posted by Rod McCoremick on Nov 6, 2018 11:00:00 AM

It’s kind of inevitable that, like death and taxes, you will have to deal with borehole deviation at some point in your drilling career. Bore holes are rarely straight and the further down you go, the more likely the chance of your hole going off the chosen trajectory. This can be quite a problem if the geologist needs to hit a particular ore body. And the fact of the matter is that many of the ore deposits near the surface have already been depleted so you need to drill deeper.

Why You Should Consider a Water Treatment System at Core Shacks

Posted by Rod McCoremick on Oct 22, 2018 10:30:00 AM

Our water treatment system Eddy has been doing well at drilling sites across the globe, including Mexico, and Northern Quebec. I’ve written about some of the successes we have had in helping customers go green and reduce water consumption. I love seeing how one product can be used successfully in different applications, and this is the case with Eddy, as new uses for water treatment are coming out.

Which Supply Pump Will Do the Job?

Posted by Rod McCoremick on Sep 24, 2018 11:01:00 AM

In our last blog, we talked about the importance of having a continuous flow of water in diamond drilling, so that the borehole is lubricated, the core bit is cooled and the drill cuttings are flushed from the hole.

Pressure Pumps in Diamond Drilling: Triplex Piston versus Triplex Plunger

Posted by Rod McCoremick on Sep 10, 2018 11:00:00 AM

In diamond drilling, the continuous flow of water is essential so you can extend the life of the core bit, lubricate the bore hole and flush drill cuttings. Mining and drilling companies alike choose positive displacement pumps as the pressure pumps used on drill rigs. Positive displacement pumps will produce the same flow at a given speed regardless of discharge pressure, providing continuous flow or in other words, they just keep on pumping.

Is Your Drill Rod Grease Really Doing What You Want?

Posted by Rod McCoremick on Aug 13, 2018 3:30:00 PM

Most diamond drillers understand the importance of lubricating all the moving parts of the drilling equipment they use – we’ve talked about it often in this blog. Lubrication will help preserve and extend the life of your drilling equipment, prevent rust and allow your equipment to descend down the bore hole faster.

How to Choose the Right Surface Set Diamond Core Bit

Posted by Rod McCoremick on Jul 16, 2018 3:15:00 PM

Surface set diamond core bits are often considered old-school tools in diamond drilling. They were the only choice for drillers years ago. Like many other things, new methods and technologies have caused diamond drilling to evolve, and diamond impregnated core bits are more common today. The surface set bit had only one layer of diamonds on the surface while with an impregnated core bit has several layers of diamonds all through the matrix.
