Investigation of Rockburst Mechanisms and Rockburst Prediction Using Numerical Modeling Methods
2023Rockburst is a sudden rock failure characterized by the breaking up and expulsion of rocks from their surroundings, accompanied by a violent release of energy. Due to its unpredictability and high intensity, rockburst is one of the most hazardous geological disasters. It has caused thousands of injuries and fatalities and significant economic losses to

Abstract : Characterization of mining-related seismic events is critical to the implementation of the Comprehensive Nuclear Test-Ban Treaty monitoring system. Mine seismicity from uncontrolled sources are particularly troublesome, with magnitudes up to 4 or 5, producing signal strengths comparable to 1-10 kiloton contained nuclear explosions. The Coeur

The Canada-Ontario-industry rockburst project
pure and applied geophysics, 1989This project was started in 1985, after a particularly extensive period of rockburst activity in several Ontario mines. Three parties participated in the project: the Government of Canada, through CANMET, the Ontario Ministries of Labour and Northern Development and Mines, and the Ontario Mining Association.

Energy, mine stability and rockbursts
1999The discussion in preceding chapters was concerned with the design of single, or mechanically isolated, excavations in different types of rock media. In all cases, a design objective was to achieve a static stress distribution, or a set of static forces on joint-defined internal surfaces, which could be sustained by the constituent elements of the rock
