The
explosives engineering industry has an excellent safety record, but increasing
attention is being paid to the environmental issues connected with rock
blasting. Blast may effect human swimmers or divers and aquatic animals
such as marine mammals and fish.
The level of the blast wave decreases with distance, and hence at sufficient
distance the effecs of blasting will be negligible. It is important to be
able to estimate this distance since it enables the area in which might
be an effect to be quantified, appropriate safety or environmental measures
to be put in place, and the most efficient use of resources to be made.
Rockfall has worked for 20 years in collaboration with Subacoustech Ltd,
a specialist underwater acoustics and blast consultancy, to provide environmental
impact assessments, and measurements, control, and mitigation of underwater
blasting.
The database comprises several thousand measurements of underwater blast
, which can be used to estimate accurately the expected blast level in a
wide range of operations.
