Many of us think that sonic drill is the only practical method we can have when the drilling project we need to work on involves penetrating through complex formations.
This is a serious concern and not to be taken lightly, most especially if you are about to take on a drilling project that might involve unconsolidated, loose, or fragile ground.
The mining sector is making use of sonic technology in drilling and working it to their advantage and does so by giving them a good chance to overcome hurdles with the highest level of efficiency. Traditional drilling methods can’t even be at par or come close to what the sonic method of drilling can deliver.
The keypoint reason why we usually have a high level of success rate with the sonic method of drilling is because of its use of resonant energy. This frequency force will come to the aid of your core barrel in advancing itself to any kind of subsurface formation you need to dig through.
While drilling activity is in progress, the energy it will generate will be carried down to the drill string and will be heading itself onto the bit face. This is a normal occurrence at varying levels of sonic frequencies. The sustained rotation of the string will help ensure that there is an even distribution of energy here. This action is likely to leave an impact on the bit face, causing the string to advance efficiently.
While the core barrel contains the sample, the outer casing is drilled over the barrel, keeping the same depth. At this point, there is no need for water or any kind of liquid. The odds that the hole will remain as stable as it is high, of special mention here are the rock formations that are susceptible to caving. What does this include? Loose sand or heaving, till, gravel, boulders, and cobbles.
In my experience, here are some reasons why employing the sonic drill method is far way more advantageous than other types of drilling styles.
Sonic cutting action can effectively sheer soil so clean that you will hardly find any traces of liquid around it, otherwise it would have diluted your sample. Eventually, the process will lead the way for you to have a relatively undisturbed sample, regardless of the kind of soil you are working on.
With this, you have better chances of getting yourself close to 100% core recovery, which is continuous to the depth. This implies that you have far superior subsurface information, which is an important factor to consider in making a decision.
Melding together vibration and slow rotation will have the casing advance in a snap through unconsolidated formations. With this, you can ascertain to have a penetration rate that is up to 3 times faster as opposed to what a traditional overburden drilling is likely to deliver.
Reduced amount of waste:
An efficient cutting process carried out without the involvement of any fluid will render a significant reduction in waste and drill spoils by at least 80%. This goes in a completely opposite direction of what you can expect to have with a conventional drilling method.
The 3 big points given above are so far among the most relevant of the sonic drilling method advantages. Employing this technology to penetrate the ground will give miners, and other professionals who need to involve this in their line of work, better chances of gaining full control in as far as planning out their projects, as well as resources management, is concerned.
It will also minimize the odds that your drilling work will fail or come across a deadlock due to unknown or often too challenging subsurface conditions. Besides, it will also reduce overall costs and time while minimizing environmental effects in between.
