Investigation of Rockburst Mechanisms and Rockburst Prediction Using Numerical Modeling Methods

2023
Rockburst 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

Microseismicity Characteristics Before and After a Rockburst and Mechanisms of Intermittent Rockbursts in a Water Diversion Tunnel

Rock Mechanics and Rock Engineering, 2021
As the buried depth of the tunnel increased, rockbursts occurred frequently during the tunnel boring machine (TBM) excavation of a diversion tunnel. In addition, multiple rockbursts occurred in the same area within a short period of time, seriously threatening the safety of workers and construction equipment.

Energy sources of rockbursts

Journal of Mining Science, 2013
The authors analyze stress-strain state of elastic plane with circular void in varied loading conditions, draw energy flow lines, highlight effect of clustered seismic events on the flow line shapes, and propose definition of rockburst probability.

The Canada-Ontario-industry rockburst project

pure and applied geophysics, 1989
This 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.

Rockburst Model Validation

2004
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

SPA-VFS Model for the Prediction of Rockburst

2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008
The exact prediction of rockburst is an urgent problem for the underground excavation in high geostatic stress environment. Set pair analysis (SPA) and variable fuzzy sets (VFS) are new methodologies to describe and process system uncertainty. In this paper, a novel model using the theory of SPA is proposed to construct the difference function of VFS ...
