Long range rockburst prediction: A seismological approach
International Journal of Rock Mechanics and Mining Sciences & Geomechanics Abstracts, 1994Abstract Rockbursts are one of the most dreadful operational hazards of mining. While it is not possible to eliminate them from deeper level mining, the risk of their occurrence and consequential losses can be minimized if the spatio-temporal occurrence of the impending rockburst can be predicted.

Revisiting Rockburst Predictive Models for Seismically Active Mines
56th U.S. Rock Mechanics/Geomechanics Symposium, 2022ABSTRACT: Rockburst is a mining-induced seismic event characterized by a sudden explosion of rock due to the release of strain energy stored in rock mass, often occurring in high geo-stress and other unfavorable geological conditions.

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

Rockburst Prediction Using Gaussian Process Machine Learning
2009 International Conference on Computational Intelligence and Software Engineering, 2009Rockburst is a geological disaster occurred usually in deep mines. Because of poor understanding of the mechanism and influence factors of rockbust, it is very difficult to give accurate prediction using conventional methods. A new model based on Gaussian process (GP), which is a probabilistic kernel machine leaning and has become a power tool for ...

Research of Rockburst Prediction and Control Technology
Applied Mechanics and Materials, 2014The paper analyzed the cause of rockburst, indicating that the risk came from hard and thick strata of roof, folding structure, fault, coal pillar and advance speed. Meanwhile SOS micro-seismic monitoring system and KBD5, KBD7 electromagnetic radiation meter was applied to monitor and measure the bumping danger zone.

SPA-VFS Model for the Prediction of Rockburst
2008 Fifth International Conference on Fuzzy Systems and Knowledge Discovery, 2008The 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 ...

Prediction of rockburst based on an accident database
2011Rockburst is characterized by a violent explosion of a certain block causing a sudden rupture in the rock and is quite common in deep tunnels. It is critical to understand the phenomenon of rockburst, focusing on the patterns of occurrence so these events can be avoid and/or managed saving costs and possibly lives.

Comprehensive Prediction of Rockburst in High-Speed Railway Tunnel
Applied Mechanics and Materials, 2013Dayanwan tunnel in Shanghai-Kunming high-speed railway is deeply buried and its rock lithology is brittle and hard. The typical tunnel cross section was selected to do hydraulic fracturing field geostress test. The stress in the measured depth was obtained. In order to forecast the rock burst in the whole tunnel, the finite element inversion method has
