Mining and Opencast Mining/ Raw Material Extraction

Absolute robustness for maximum reliability

Deep underground there are high temperatures, extreme vibrations and shocks. Durable and resistant technology is a must when it comes to withstanding these conditions. Our robust, wear-free and high-precision position measurement systems are particularly well suited for work under extreme conditions. With 25 years of relevant experience in position measurement in mining and maximum precision, Balluff's systems provide workers with maximum security.

Application examples

  • Supporting tunnel mining

    Safety in tunnels using precise position measurement systems

    The solution

    Shields with hydraulic cylinders are used to protect miners in tunnels from falling rocks. BTL magnetostrictive linear position sensors of the K series integrated into the hydraulic cylinders allow exact positioning and secure monitoring of the shields.

    The features

    • Compact design
    • Explosion-protected versions
    • made from stainless steel
    In mining, tunnels are supported by shields with hydraulic cylinders

  • Monitor drilling depth in raw material extraction

    Efficient mining of raw materials thanks to reliable monitoring of the drilling depth

    The solution

    When blast holes are drilled under ground, our BTL profile magnetostrictive linear position sensors installed outside of the cylinders monitor the drilling depth. The highly robust position measurement systems also operate reliably under extreme conditions. And ensure the necessary safety in tunnels as well as efficient mining of raw materials.

    The features

    • Easy installation and fast exchange, since they are externally attached
    • Extremely robust against shock and vibration
    • Reliable, even at high ambient temperatures

  • Position drillers for soil samples

    Efficiently search for new raw material supplies using contact-free position measurement systems

    The solution

    When searching for new raw material supplies, mobile drillers take soil samples to confirm potential deposits. Our BTL PF magnetostrictive linear position sensors are distinguished by their flat design and reliably ensure the correct drilling depth. So that you always know where the driller is.

    The features

    • Flat design, space-saving for mobile machines
    • Robust profile housing
    • Wear-free, since it is contact-free with up to 15 mm distance from the position encoder to the transducer
    Monitoring the drilling depth for movable drillers

  • Controlling pushing cylinders in tunnel construction

    Efficient and smooth drilling process through BTL magnetostrictive linear position sensors

    The solution

    In tunnel construction, boring machines remove rock centimeter by centimeter. Pushing cylinders, which continuously force the drill head into the rock, provide the strength needed for this. Our vibration-resistant BTL magnetostrictive linear position sensors correctly report the piston position with precision ( even under extreme conditions) and permit a smooth drilling process.

    The features

    • Reliable
    • Wear-free: Long life for the highest system availability
    • Vibration-resistant: For use under extreme conditions
