Control Measurements and Vibration Monitoring as Documentation of the Impact of Blasting Operations on the Surroundings of Open-Pit Mines

Abstract

The use of explosives in surface mining operations generates seismic vibrations that may affect nearby structures. To mitigate environmental impacts and address potential structural damage claims, systematic documentation of blasting effects is essential. This paper presents methodologies for control measurements and continuous vibration monitoring, including the use of the Mine Vibration Monitoring System (MVMS). Control tests verify the accuracy of vibration intensity predictions based on explosive charge mass and distance, while monitoring provides real-time data and long-term records of vibrations at protected buildings. Case studies from limestone quarries confirm that most blasting-induced vibrations fall within safe thresholds defined by the SWD-I scale, with only isolated instances reaching levels that might raise concerns. Importantly, no damage progression was observed during such events. These findings support the effectiveness of current monitoring systems and indicate that controlled blasting, when properly managed and documented, does not pose a significant threat to nearby structures.
