Sonic sampling for mining

Share this page

Main information

Why do you need sonic:

  • High sampling rate per day
  • High quality samples in all types of geology
    (CoreBarrel sampler & AquaLock sampler)
  • Sonic drilling is multifunctional usable: for rehabilitation program, installation of piezo meters, water wells, etcetera.
  • Can be used in combination with conventional techniques
    (CRS-V Duo, Sonic rigs)
  • Safe and ergonomic working method

Your challenge

Sampling activities for mining are often negatively influenced by the generally poor quality of samples you obtain with traditional drilling techniques. Slow advancement of the drill results in your field specialists wasting their time, and a drill grid that is insufficiently explored. Because of poor engineering data due to bad sample quality, high costs will occur in the long run. 

Our answer 

Our Sonic drill rigs, together with our special soil samplers and rock coring tools have proven to produce the correct data in short time. Samples are long, show accurate depth information and are highly undisturbed. The stunning drilling speed, low sound level and ergonomically balanced operation make that people like working with our Sonic rigs and smart sampling tools. We produce our rigs and tooling according to detailed and demanding EU standards.

Features

Sampling mixed layers

Do you need to take samples in wet sands or in a profile with mixed layers? Our patented AquaLock sampler system can handle it all. It is the fastest and most reliable sampling tool for alluvial deposits in combination with a Sonic drill head. You can use the AquaLock for continuous sampling or discreet sampling. 

Drillers reach optimum drilling speeds by matching the frequency of vibration to the natural frequency of the ground. Efficiently penetrating the formation, sonic drills can consistently obtain close to 100% sample recovery in mine dumps, stock piles and heap leach pads, particularly when operated by a seasoned drill crew.

Sampling hard formations

With other formations than sand, loam, peat or clay, our CoreBarrel is the right choice. You combine vibration with rotation to allow the Tungsten carbide buttoned ring bits to cut through the harder formations. 

Sampling rock 

The CoreBarrel DualWall sampler is designed to take cores from rock and very hard layers and can be cased with a 6”, 5/8” or 7” casing.

Extremely straight boreholes 

The sonic method of drilling also creates an extremely straight borehole, making it an optimal technology for installing instrumentation and monitoring equipment. Drilling contractors use sonic technology to install inclinometers that monitor the formation and help mining operators to know if the ground is subsiding or moving, so they can catch dam failure before it occurs. In the event of an earthquake or other large geologic events, mining companies can quickly gain an understanding of the impact to the tailings dam. But contamination and toxic leak monitoring is perhaps one of sonic drilling’s most important contributions, enabling drillers to efficiently return precise samples of ground surrounding tailings impoundments and heap leach pads to determine if it has been contaminated.
