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.
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.
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.
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.
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.
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.
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.
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.
At PDAC last March, we displayed and introduced our customers to our tallest crown configuration yet: the Vulcan 40 mm. Our line of Vulcan configurations had included a 16 mm, 20 mm and 26 mm option so this newest addition really took the bar to a whole other level. Many customers were intrigued and had many questions about how to use such a crown. This blog will take a look at the Vulcan 40 mm and how and when is should be used.
Geotechnical drilling is different from diamond drilling yet sometimes they can both benefit from the same piece of equipment. The Elepump KF-50M mud pump is a case in point. One of our geotechnical drilling customers recently used this great little pump and it resulted in a quick case study that provided three good reasons why geotechnical drilling companies should consider using a KF-50M pump and I’m going to share them with you here.
