Akustikverkstan Consulting Open Pit Mining Vibrations

OPEN PIT MINING / VIBRATIONS. Vibrations and acoustics are two closely related fields. Acoustics is vibrations in air which can be caused by vibrations in ground. When blasting rock, both vibrations in the ground and in air is generated. We can measure the pressure at the shockwave as well as vibrations in the ground and on buildings close to ...

If you have sufficient velocity/distance data, you can derive your own effective PPV ref and exponent from it. ↩. [9] Mining operations which carry out blasting use the scaled-distance equation, v=K (D /√W) -b to calculate vibration velocities at distance from the blast. The quantity, D /√W, is the scaled distance.
