Improving your rate of penetration will have a direct impact on profitability as it will increase productivity and lead to recuperating more core. How to achieve better penetration is a challenge for many drillers but there are several methods that will help.
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.
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.
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.
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.
When geotechnical crews perform excavations, it is crucial that engineers determine a safe slope angle, especially in situations where the ground is clay, silt or other fine-grained soils. A simple and quick test that estimates the undrained shear strength of saturated soils is the vane shear test.
A major challenge for any driller is trying to drill with flowing sands. The term flowing sands refers to a mixture of fine sand and water that infiltrates drilling equipment. This problem often arises when using hollow stem augers to perform SPT tests.
In most geotechnical and environmental drilling, augers are used to drill in the majority of projects. However, the need still arises to perform core sampling for certain geotechnical projects, usually when the presence of bedrock needs to be confirmed. An auger or split spoon will not be able to enter the bedrock so drillers have to use core sampling methods to be able to penetrate and obtain a core sample.
