    Planning to comply

    Planning to comply with statutory vibration limits associated with blasting

    Planning to comply is a key concept that we promote throughout industry and has been adopted on many of the operations that we were involved with.

    This methodology can be employed by operators to clearly demonstrate to any authority or residents group that they are indeed planning to comply with their vibration limits.

    This process actively uses the collected vibration results rather than 'monitoring for compliance' or leaving it to chance.

    Please click above to download a copy of the planning to comply paper. The paper outlines the pitfall of 'monitoring for compliance'.

    Reducing the environmental effect of aggregate quarrying: dust, noise and vibration

    Reducing the environmental effect of aggregate quarrying: dust, noise and vibration

    The wide range of ALSF projects connected with the three environmental footprint elements of dust, noise and vibration have been considered in one review report, completed as part of a wider review of the ALSF research programme relating to land-won aggregates.

    The projects include assessments of potential impact, development of new monitoring equipment and methods, and application of new operational systems and techniques to mitigate any effects.

    Topics include:

  • The effects of quarry blasting and the environmetal impacts produced
  • A thorough explaination of ground vibration and air overpressure
  • The measurement of blast vibrations and the seismograph
  • A detailed explaination of vibration levels relating to structural damage criteria
  • Human perception to vibration and disturbances within buildings
  • The major contributing factors that affect air overpressure
