ABSTRACT

Earthquakes triggered or induced by mining may cause damage to underground and surface infrastructure, loss of production, and injury to mine workers and the public. As shallow ore bodies are exhausted, mining depths are destined to increase, giving rise to situations where the stress exceeds the strength of the rock mass and making rockbursts more likely. Microseismic monitoring and analysis is used to mitigate the risk posed by rockbursts by enabling rescue efforts, guiding the design and implementation of mining layouts and rock support systems, and assessing seismic hazard. Current practice is reviewed, and standards, procedures and guidelines for the design and operation of a microseismic monitoring system are provided.
