It is common for measurements of ground and air vibrations to be made during blasting, to ensure compliance with statutory requirements. Utilising Oricas Rock On Ground (ROG) service the Linwood Quarry has reduced the average overpressure readings by 24% and reduced the standard deviation of these readings by 33%, enabling improved overpressure control without negatively affecting other blasting outcomes.

Mar 19, 2020 In most civil construction blasting projects and some quarry sites, where measurement is conducted in the near field (ie the distance to the monitor is comparable to the blast dimensions), a good blast designer can use advanced blasting techniques to channel vibration frequencies above 35Hz and thus the limit of 25mm/s would apply. Mar 29, 2021 Such multiple, timed detonations are most efficient at moving the rock, while minimizing the undesirable side effects of ground vibration, noise, and rock fragments thrown large distances through the air (flyrock). A very active surface mine (e.g. a large coal mine) may blast once per day. A typical quarry will blast once or twice a week.
