Their steadfast commitment and innovative thinking have led to the development of one of their standout products, the LS250 MiniSonic sonic drill rig. This article delves into the distinct advantages, features, and tips related to the LS250 MiniSonic, shedding light on why it has been a significant step forward in the realm of sonic drilling.

The Sonic Drilling Revolution

Sonic drilling, a high-frequency resonant drilling technique, has emerged as a transformative approach within the drilling industry. This advanced method ensures smooth advancement of a core barrel or casing into the subsurface formations, providing a myriad of benefits over conventional drilling methods.

Boart Longyear has been at the forefront of this sonic drilling revolution, contributing cutting-edge technology and expertly trained sonic drillers to the industry.

Sonic Drilling: When and Where to Use?

Knowing when and where to utilise sonic drilling over conventional methods can significantly enhance cost-effectiveness and efficiency. Sonic drilling becomes the preferred choice under three main circumstances:

  1. Projects necessitating a continuous in-situ sample collection rather than collecting chips, as in the case of reverse circulation (RC) drilling.
  2. Situations that demand the avoidance of fluid and air while drilling. No fluid or air is needed in sonic drilling, making it an ideal choice for geotechnical, geo-construction, and environmental applications.
  3. Projects encountering unconsolidated ground formations. Sonic drilling is adept at handling pebbles up to boulders while ensuring borehole integrity through a continuous casing process.

Boart Longyear’s LS250 MiniSonic: An Overview

The LS250 MiniSonic is the brainchild of Boart Longyear, designed to cater to a wide range of soft ground shallow drilling projects, including environmental, tunneling, water management, grade control, and leach pads. The rig features the MiniSonic head, which has a proven track record of over a decade in the field, offering reliability and performance.

Key Features of the LS250 MiniSonic

https://rigsalesaustralia.com/used-drills-and-parts-for-sale/boart-longyear-ls-250-mini-sonic/The LS250 MiniSonic drill rig comes packed with an array of key features that make it a standout in the world of sonic drilling.

  1. Compact and Cost-Effective: The compact and smaller footprint of the LS250 MiniSonic makes it versatile for small drill pads, environmentally sensitive, or hard-to-reach sites. Its wide 600 mm rubber tracks offer low ground pressure (0.3 bar/4psi), perfect for jobs in the most sensitive and fragile terrains.
  2. Safety First: The LS250 MiniSonic is CE compliant, featuring an interlocked rotation barrier that slows the head rotation when open, thereby enhancing safety.
  3. Operator Comfort and Safety: The LS250 MiniSonic features a rod presenter where rod and casing can be loaded horizontally. The head rotates 28 degrees to the side for sample extraction. The head slide shift allows for unobstructed winch use down the hole, ensuring maximum operator comfort and safety.
  4. Easy Operation and Maintenance: The LS250 MiniSonic features a pilot-operated hydraulic system, which makes it easy to operate and maintain.
  5. High-Efficiency Rotation and Oscillation Unit: The patented airbag system isolates the vibration from the rig and transfers it down the hole for more efficient drilling.

Tapping into the Power of LS250 MiniSonic

To maximise the capabilities of the LS250 MiniSonic, it’s essential to tap into its full potential and understand its operation in-depth. Here are some tips to get the most out of sonic drilling with the LS250 MiniSonic.

Choose the Right Drill Bits and Shoes

Opt for the correct drill bits and shoes based on the ground conditions. For unconsolidated ground, consider the rock sizes and adjust the core barrel accordingly.

Telescope the Core Barrel

Friction is the enemy in drilling. Telescoping the boring can significantly reduce friction and take the boring deeper. The core barrels should be adequately sized to the casing size for optimal results.

Engage and Explain

The LS250 MiniSonic and sonic drilling, in general, may still be new to some Drillers. Taking time to research and comprehend the process and technology can help you appreciate the benefits of this method.

Prioritise Safety

Safety should always be the top priority on any drill site. Encourage a safety culture within the team. A “think before acting” approach is advisable, which allows the crew to focus on the task at hand, one task at a time.
