Fountain rockburst and inductive rockburst
Journal of Central South University of Technology, 2000A new test method—the load relaxation test after the peak value, was used to investigate rockburst proneness. Two new concepts—fountain and inductive rockbursts, were proposed to distinguish two kinds of rockbursts. The breaking process of rock, mutation condition and occasion of rockburst and source of kinetic energy of rockburst were discussed.

Rockburst occurrences and microseismicity in a longwall panel experiencing frequent rockbursts
Geosciences Journal, 2018A rockburst is a kind of dynamic geological hazard faced by engineers and researchers. Identification of a potential rockburst risk area (PRBRA) allows effective, targeted measures to be taken mitigate these hazards. To provide a reference for determining PRBRA in longwall panels with similar conditions, an in situ investigation that lasted for over ...

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.

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.

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

Rockbursts in Ostrava Karviná Coalfield
2017The phenomenon of rocbursts has accompanied mining in the Czech part of the Upper Silesian Coal Basin (USCB), just as it has in the Polish part, since the beginning of the last century, and its consequences remain pertinent today in the Karviná part of the Ostrava-Karviná Revir (conventional term for Czech part of the USCB, hereinafter referred to as ...
