When it comes to drilling, it is very important to choose the right kind of drilling equipment. This will not only ensure that the job is done the right way, but this is also a way for you to protect your investment. Here are some things you need to consider when choosing the right drilling rigs equipment for your needs.
Underground drilling needs definition drilling. Its focus is on speed and production, especially that you wouldn’t want to slow down the extraction part of your operation. With this, being able to achieve the best rate of penetration is a must. A core bit that could cut rock well and possesses a good rotation speed can offer a better rate of penetration.
Unknown Ground Vs Known Ground
The majority of mines have been in operations for a long time so the kind of rock would not be a mystery. Some holes would have already been drilled so the team will also be informed on what they should be expecting and there will be no surprises. At the same time, there is no need for drillers to limit their choices to core bits that are suited for a very wide variety of ground; instead, they can focus on bits that have been developed for ground types. In addition, since the type of ground is identified, it is possible to opt for a higher crown so the number of times that you need to chance the bit will be greatly reduced.
In terms of underground drilling, usually the holes are not so deep. This is likely to lead drillers to opt for conventional drilling methods, instead of using wireline drilling methods. The thin kerfs in the core bits utilized in conventional drilling could lead to a much better rate of penetration.
In underground drilling, the direction of the borehole could either be up, down, or angled. Having these varied directions means that you may opt to choose another matrix for your core bit. In some cases, when drilling an up hole, you can change the matrix that you would normally use in a downhole and take it one series higher.
Usually, underground drilling offers lesser space for drilling rigs so they will be less powerful and smaller. If you are drilling with a low-powered drill rig, like an up hole, you would need a core bit that has a softer mix. As what has been mentioned above, the softer mix has diamonds that gets easily exposed and would allow the core bit to cut well, stay sharp, and offer a good rate of penetration even when using a machine that does not give you the needed feed pressure.
By considering all these things, you can be confident that you can maximize the use of your equipment and get the best value for the money that you have invested.
