Nothing is as discouraging as becoming “stuck in the hole”, yet is it not uncommon in drilling.
While there are many ways you can be stuck in the hole, they all have the potential to stall operations and result in lost productivity.
Certain ground conditions can lead to your equipment being jammed.
Clay can swell enormously when water is introduced and this swelling can trap the rod and drill bit.
Coming across sand can also be harmful as the sand can collapse around the drilling equipment.
On the other hand, the rod string can also break, either from too much pressure or by being dropped, and you will need to try and retrieve it. Finally, a bit that has melted and fused to the rock is a bad situation that will stop operations quickly.
In each case, especially if you have achieved a significant depth in drilling over a long period of time, it is preferable to try and retrieve what equipment you can than to start over drilling a new hole. Different methods and DTH products are available depending on the situation.
If you have dropped your rod or it has broken in the hole, you can use recovery tools, fishing tools, or casing cutters to try and retrieve the rod.
If unsuccessful, wedges can be used to deviate from your original borehole.
Some guidance in proper hole maintenance, and how to use water to improve conditions can also be helpful.
Our technical onsite support team can visit a drill site and offer corrective solutions quickly so you are up and running as soon as possible.
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.
