Vibration monitoring standards connected to the use of explosives in Different Countries

The paper is part of the ongoing work within the Environmental committee of EFEE. The aim is to assist experts working with explosives one of the aims is to improve the common knowledge of similarities and differences between national legislation, standards or guidelines on vibration monitoring and other environmental monitoring when blasting around the world.

Initially, an online survey was performed through most of 2018. Questions were made regarding vibration monitoring during blasting. The existence of norms, guidelines or standards and how they are used in different countries.

The questions were designed to try to map the different national standards use of such things as frequency, guidance on monitoring position, the distinction between different types of structures, the requirement to the equipment and more. Furthermore, a few initial questions were raised on other environmental monitoring relevant for blasting.

The respondents were national, cooperate, affiliated (ISEE} or individual members of EFEE. The answers where experts in the use of explosives and vibration-monitoring in their respective countries. More than 60 respondents have answered the questionnaire from 29 different countries.
Initially the incoming answers were analysed and the differences and similarities with focus on European vibration monitoring were clarified and mapped. Trends of other environmental monitoring standards were also analysed. Where needed the different guidelines, standards and regulations have been visited to verify the answers and further elaborate on the comparison.
