Core Matrix Troubleshooting: Overly Exposed Diamonds

Posted by Rod McCoremick on Feb 13, 2017 10:30:00 AM

 

We’ve talked a lot in previous blogs about the importance of choosing the right core bit and the right core bit configuration, so I think it is time we talk about getting the most out of your core bit. 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 lack of experience.  One of the best ways to determine what is off is to examine the wear profile of your bit crown and change drilling parameters if necessary.

Bore Hole Maintenance 101

Posted by Rod McCoremick on Nov 21, 2016 10:42:25 AM


In diamond drilling, your bore hole plays an important role and will have a large impact on your drilling performance.  A bore hole is like a road – it must be maintained. If you want the road that transports your equipment to be even, smooth and durable, you need to perform regular maintenance. Large trucks and equipment that run over it hourly can be damaged if the surface is crumbly, and full of pot holes. Your bore hole needs the same kind of care. Your bore hole is like a road that transports your drilling equipment.

Diamond Drilling 101: No Water Circulation

Posted by Rod McCoremick on Nov 14, 2016 10:30:00 AM

 

Unless you hear from another driller who has already drilled in your zone, there is no way to tell if you will encounter a problem with water circulation. Some areas are notorious for having voids, fractured ground or underground rivers. These include Nevada and the western USA, as well as a large part of South America. Large geological faults that run through these areas are often to blame for the ground conditions.

5 Good Reasons to Fill Out a Core Bit Tag

Posted by Rod McCoremick on Nov 7, 2016 10:30:00 AM

 

Most of us know what a bit tag is – that little piece of paper that comes with a new core bit. However, a lot of drillers don’t fill out the information requested on the tag. They’re “too busy” or they think they have better things to do…like drill. Yeah, we get it, but those bit tags can help make your life easier and it is a good habit to get into.

How Fractured Ground Conditions Affect Diamond Drilling

Posted by Rod McCoremick on Oct 24, 2016 10:30:00 AM

 

The kind of ground conditions a driller encounters will play a huge role in how the project goes and the types of decisions he will need to make.  Ground conditions include more than just the hardness of the ground and choosing the right matrix for a particular hardness. While important, other decisions will need to be made.

5 Precautions to Take When Setting a Wedge

Posted by Rod McCoremick on Oct 10, 2016 10:30:00 AM

 

 

No matter how carefully you planned and drilled, bore holes are rarely straight. Many things can have an effect on the direction of the hole, such as weight on bit, poorly set up drill rig, fractures or voids in the ground formation, bedding planes, or ground that goes from hard to soft. Too often, the path of the bore hole needs to be corrected in order to reach a desired target and that is when you should consider using a wedge.

5 Tips to Improving Your Drillers’ Log

Posted by Rod McCoremick on Sep 19, 2016 11:25:11 AM

 

Many diamond drillers are familiar with a driller’s log. It is a report that is completed by one shift to track any and all activity on the drill site and it can also provide certain details for management. The details included on the driller log can include a variety of items including changes in ground formation, the number of hours worked, the number of hours of downtime, if any, the consumables per shift, the number of meters drilled and the point they started drilling and finished drilling.
