Ground vibration resulting from blasting, has become a critical environmental issue with the increasing mining activities in areas close to human settlements and many a times the locals resist the blasting even though it is not causing damage to their structures. In general, apprehensions or perceptions have been increasing probably because of awareness or genuine concern or vested interest. This paper presents the measurements and analysis of blast induced ground vibration at one of the limestone quarries in Southern India, where the villagers had the apprehension with regard to adverse impact of blasting on their water head tank and other permanent structures within the village. Conventionally these kind of complaints conclude with field studies leading to establishment of a site specific predictor equation and arriving at the permissible maximum charge per delay for the limit as per the prevailing norms. However, this paper goes beyond by providing a means of representing the field observations in a simple form understandable by all the stake holders for ensuring a permanent solution. The approach can be used as a guideline for addressing vibration issues in many operating or proposed quarries. Keywords—blast vibration; vibration issues; vibration approach; limestone mine blast vibration.
