Drilling in Hard Rock

Posted by Rod McCoremick on Feb 5, 2019 11:00:00 AM

In a previous blog, we discussed some of the issues you encounter when drilling in soft rock. This time, we’ll look at the opposite end of the spectrum: hard rock. Hard rock is defined as being over 6 on the Mohs scale of hardness. Common types of hard rock included kimberlite, granite, chert, quartz and silicified rock.

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.

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.
