Top drill rig companies in the aggregate industry make use of sonic technology in assessing the probable quality of both sand and gravel deposits. It has been found that drilling the aggregate with a sonic device offers significant advantages which companies involved in the drilling industry must take advantage of.
By applying resonant energy, sonic drilling can advance the core barrel into any kind of subsurface structure. Sonic frequencies are involved while drilling work is in progress as the vibrational energy in the drill string is funneled down the bit to the bit face.
The string rotates simultaneously and concentrates the energy and impact on the bit, distributing the energy and impact more evenly over the string’s surface. The outer casing is then drilled to the same depth as the main barrel. This does not necessitate the use of any fluid or water.
Distinct Benefits of Sonic Drilling
Superior Quality of Information
This approach produces a fairly undisturbed ground sample because the sonic cutting action shears the soil cleanly without using any kind of fluid that will dilute the sample. Core recovery is almost 100% and stays deep in the subsurface, which allows better knowledge for decision-making.
Vibration and slow rotation provide for an increased advance rate, which is significantly helpful when drilling work is in progress through unconsolidated formations while yielding penetration speeds up to 3 times faster compared to those that can be experienced while drilling overburden.
Reduction of Drilling Waste
Drill breakage and waste are decreased by as much as 80% when the drilling is done efficiently and without the use of water or any liquid. When miners have this power, they are better able to determine the best course of action for their ventures and to manage their capital.
Reduced total time and costs by virtue of sonic drilling help you to avoid the risk of a project fiasco or having a prolonged project which is often brought about by unknown or unforeseeable difficult subsurface conditions. Besides, it comes with an adverse environmental impact, too.
Sonic drilling is useful for many mining applications because of these advantages. Drill rig companies can sample unconsolidated ore piles and use tabulation techniques to estimate reserves out of current legacy stockpiles.
These stockpiles are typically depleted of ores. They may also examine leaching efficacy, identifying dry conditions and enhancing the leaching process, and increase the yield of the desired minerals.
A complete rig setup usually has these characteristics that make them highly suitable for shallow drilling into an overburden or pre-collaring before drilling with a traditional drill.
Sonic drilling is ideal for geotechnical research for building and mine construction projects. Sonic rigs that are smaller and have lower ground pressure can be taken advantage of in environmentally sensitive areas, like when you need to drill without creating any damaging impact on the pavement. It is also very ideal to use when you don’t want to disrupt existing grass beds, or even enter murky wetlands.
