Should You Choose Reverse Circulation Drilling for Your Project?
If you are planning for an exploration or grade control drilling project, you should consider using reverse circulation as your drilling method. This technique uses a drilling rod with dual walls during operation. In general, the equipment has an inner tube inserted within the outer drill rod. When the rod is inserted into the substrate, the inner tubing allows the drill cuttings to be collected in a continuous flow at the surface. This efficient process can be attributed to the pneumatic piston which crushes samples for easy collection. This component also provides air which pushes the samples upwards, ensuring that the collection procedure is fast and efficient. If you are uncertain about using reverse circulation drilling, here are the primary advantages of the method that you should know.
Collection of Uncontaminated Samples
Reverse circulation drilling produces substrate samples which are uncontaminated and therefore, reliable. When the ground is cut, and the material enters the rod through the bit, it moves directly into the inner tubing. In simple terms, the cutting is not introduced to another channel or hole after the initial collection. The cuttings will move from the ground directly to the surface. As a result, there is no cross-contamination with other materials. With this technique at your disposal, you can collect numerous reliable samples.
High Penetration and Collection Speed
The penetration rates achieved through the use of reverse circulation equipment are exceptional even in comparison to open cut drilling. Simply speaking, the velocity at which the sample flows through the inner tubing to the surface is high. This speed can be attributed to the use of the pneumatic piston and compressed air to move the samples. Typically, the production rates which can be achieved through this technology is often higher than alternative methods like diamond drilling. As a result, the substrate cuttings can be collected rapidly but safely. You can reduce the amount of workforce and time required for your project.
Versatility of the Drilling Method
Reverse circulation drilling is an ideal method for use in tough conditions, particularly in the harsh environments around Australia. For instance, this technique does not require a lot of water for ground penetration like diamond drilling. Therefore, it is suitable for your project if you are planning on working in adverse conditions. This aspect also means that this method can reduce the total costs of your drilling work.
For the best results, you should discuss all your exploration or grade control drilling options with a drilling and blasting contractor, like one from Rock On Ground.
