Abstract:
Microseismic monitoring is a critical tool that is widely used in the mining and petroleum industries to provide information about changing stress conditions of the rock mass. The equipment is also readily applicable to geotechnical applications, such as railway, structural and blast monitoring. In this paper, a comparison is made between two types of blast monitoring units. Blast and vibration monitoring units can seamlessly integrate with existing seismic monitoring systems or be deployed independently. The versatility of the systems is discussed with examples from three recent applications. The first application shows how, in the near-field, sensors have been used to help engineers optimise blast sequences and quantify the effect of blasting on nearby ground support. The second and third applications show the application of microseismic sensors, in publically sensitive locations, to monitor vibrations generated as a result of mining activity or industrial power generation units to ensure they do not exceed locally recommended guidelines. Vibration and blast monitoring systems are an easily deployable hardware and software package that can successfully record near-field or far-field vibrations, providing operators with useful information for each application.
