Apart from the uncertainties mentioned two others may be noted. There appears to be little variation pound for pound among the common blasting materials in vibration levels produced at a distance.

Design of blasting pattern in proportion to the peak

 · Ground vibration is a side effect of blasting and causes the destruction of buildings and other surrounding facilities. Different damage mitigation standards have been presented in this connection. Ground vibration is affected by parameters of blasting pattern design distance from blasting site and explosive weight.
