First and foremost, you need to pick the right core bit for the type of ground you will be drilling. You should refer to a matrix selection chart to help narrow down your choices.
Once you have an idea of the matrix you need, you will also need to consider the type of waterway configuration. You will need to look at the pattern, the number of waterways as well as the width between the waterways as all of these play a role.
For example, when drilling in broken ground that is not very hard (3-5 on the Moh scale), you could choose a Hero 3 with a cyclone configuration. Other options could include core bits that are self-sharpening, such as the Hero 11 Abrasive. This kind of core bit has a matrix that has been developed to provide excellent penetration rates.
Drill holes can be very unpredictable in the path that they take, so drillers often have to deal with hole deviation. Drill hole deviation is when the hole ends up going in a direction other than the chosen trajectory. The installation of the wedge is done easily in a few steps.
Getting the longest life possible for your core matrix is a key consideration if you want to run a productive and profitable drilling operation. Changing a drill bit takes time especially the farther down the hole it is, and the time spent replacing a bit is not productive.
Abrasiveness is a ground condition that can cause headaches among many drillers. It can be difficult to drill through when present in any hardness of ground. Abrasive ground and rock can wear down drill bits quickly and in the case of hard abrasive ground, iron ore poses a particular problem and is often referred to as a bit cemetery.
While underground drilling is similar to surface drilling, there are still important differences. Our underground solution includes products that offer optimum performance in underground conditions.
Are you struggling to find ways to reduce your water consumption? Water shortages, emphasis on environmentally safe practices, government restrictions and regulations for drilling and mining companies – all combine to increase pressure on companies to find ways to reduce and recycle the water they use.
