Monitoring Vibrations from Quarry Operations

Malta has a number of quarry operators that are engaged in the extraction of hardstone through blasting operations. The Environment and Resources Authority oversees the implementation of regulations and legal obligations related to quarry operations in terms of monitoring of vibration levels from blasting operations. Given the environmental concerns associated with these vibrations, the Authority has issued terms of reference (TORs) and a guidance document on vibration monitoring of quarry blasting. The purpose of these guidelines is to improve environmental performance by providing quarry operators with details as to how and what is required in order to monitor vibrations from blasting operations. Maximum vibration levels that shall be considered acceptable are also being specified.Apart from providing details on the parameters that need to be monitored, these guidelines clarify responsibilities of the operators,  stipulate threshold levels for vibration monitoring and determine other specifications related to location, design and sensitivity of the monitoring equipment. In addition, the TORs also provide guidance on the documentation that needs to be submitted to the Authority prior to the commencement, and upon completion of the blasting operations.

Monitoring Reports for Quarry Blasting

The information provided in these reports is based on current available data and approved methodologies, which ERA is still in the process of reviewing.

When interpreting or correlating data in these vibration reports or between vibration reports from different quarries, various factors are to be taken into account. These include Peak Particle Velocity (mm/s), distance from seismograph (m) and the frequency (Hz) at which the readings are taken. Data collected from a monitoring point cannot be compared with a published standard unless all parameters are factored into the interpretation of the results.
