Construction Vibration Damage Guide
The perception of blast vibration is further complicated by the presence of ground vibration and air vibration, which separate with distance because of the different propagation velocities. Both air and ground vibration are commonly perceived by secondary noise, such as rattling of dishes, windows or sliding doors, and without monitoring it may not be possible to recognize whether air or

The vibration level at a distance depends on charge per delay, vibration frequency, rock characteristics (type, unit weight, layering, slope of layers), blast hole conditions, presence of water, propagation of surface and body waves in the ground, and to a lesser extent on method of initiation. Fractures are developed in rocks due to tensile and shear stresses. Hence, studies of blast-induced

Blasting is widely used in quarries and mining production processes. It is the beneficial industrial technology which provides achievement of expected results in a short period of time with relatively low cost. Never one less, blasts produce undesirablevibrations and sounds. This current investigation reports the ground motion and airblast over pressure measurements around the open pit mine

Ground Vibration Monitoring Standards and Methodology. If measuring ground vibration and air over pressure, set the record time to two seconds longer than the expected blast duration plus 1 additional second for every 1100 feet from the blast.
Blast vibration and air blast regulatory limits. Ground vibrations related to rock blasting result in several deleterious effects on mining, construction, quarry, and pipelines. Worldwide, numerous researches have been conducted to provide damage criteria such as energy, energy ratio, displacement, velocity or acceleration.
4 Update on Linwood Quarry BLASTING • TW tabled the air blast and vibration recordings tables over the last year, explaining the results and confirming that discussion regarding Linwood Quarry’s blasting had been previously discussed earlier in the meeting. • TW confirmed that these results would be placed on the website as soon as possible.
based on specialist knowledge, and information provided in the literature concerning ground vibration, air blast, dust, fumes and fly rock and on the opencast strip mining method. It is also based on the blast designs and bench heights for overburden and interburden provided in the information pack provided by Synergistics (Pty) Ltd (Synergistics).
6 SAFE GROUND VIBRATION AND AIR BLAST LEVELS The Department''s policy in reducing ground vibrations and airblast levels is just as much directed towards minimising distress to people as avoiding damage to buildings. Since humans respond to levels of ground vibrations and airblast considerably lower than those necessary to induce structure
