ABSTRACT

The detonation of explosives in a blast produces four

key outcomes: displacement of the rock into a muck-

pile; a fragmentation distribution of the broken rocks;

damage to the surrounding host rock containing the

original blast pattern, and finally some environmen-

tal outcomes such as ground vibration, airblast, dust

and gasses. In general, the environmental outcomes

are nuisance outcomes and the blaster wishes to mini-

mise them. For example, people located near the blast-

ing area whose comfort or property is affected may

demand a vibration reduction. A necessary part of

that process is to measure the vibration levels. In this

paper, a review of the measurement, modelling and

management of ground vibration will be considered.

Airblast will not be discussed specifically; however,

many of the issues described here for ground vibra-

tion have a counterpart in airblast. In what follows

the word “vibration” will be used to describe ground

vibration, and where the context justifies it, vibration

may refer to airblast also.
