Guidelines for the Development of Re-Entry Protocols in Seismically Active Mines
The Health and Safety Issue
A common characteristic of deep mines in hard rock is induced seismicity. The unpredictability of seismic events makes management of their effects difficult. Following large seismic events, access to affected areas is normally restricted for a period of time.

The Research Project
The objective of the project is to produce practical guidelines for the development of re-entry protocols into seismically active mines. Preliminary guidelines were prepared during the first phase of the project, completed in 2007. The preliminary guidelines were based on an analysis of currently used re-entry protocols together with their mine-specific details such as depth, rock type and properties, mining method, and site geology. During a new 3-year project, Queens researchers will collect historical seismicity information from a number of participating mines, monitor blast-induced seismicity around stopes at two selected operations, and analyze this large database of mining seismicity in order to prepare the revised re-entry guidelines.
