Among the series of publications presented at the WTC in Naples, find the ITAtech report N° 11 on Practical Approach for Controlling Blasting Vibration and Optimizing Advance in Tunneling produced by ITAtech activity Group Excavation.This document introduces some guidelines to help make the best use of drill-and-blast (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 available.
