This document introduces some guidelines
to help make the best use of drill-andblast
(D&B) – techniques in underground
tunneling at vibration sensitive locations.
Strict vibration limits can considerably
restrict D&B work, increase cost or
even prohibit its use. Good planning
of controlled blasting can often
accommodate such restrictions.
This document does not cover vibration
measurement methods or pre-estimation
of allowed vibration levels, but merely
describes practical suggestions of how
to utilize vibration measurement in D&B
pattern design and detonation control.
Second and main target of this document
is to introduce a suggestion of global
data bypassing format between vibration
measurement systems and D&B design
programs so that this data would be easily
