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 ...

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.

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

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.

A data-driven fuzzy model for prediction of rockburst
Georisk: Assessment and Management of Risk for Engineered Systems and Geohazards, 2020Rockburst is the sudden ejection of highly stressed brittle rocks. This can impose major risks on underground projects.

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.

Rockburst mechanism and prediction based on microseismic monitoring
International Journal of Rock Mechanics and Mining Sciences, 2018Abstract In this study, the rockburst definition is comprehensively described and several main rockburst theories (the strength theory, the energy theory, the bursting liability theory, the rigidity theory and the instability theory) are analyzed.

Prediction of rockbursts by analysis of induced seismicity data
International Journal of Rock Mechanics and Mining Sciences, 2001Abstract This paper describes a technique for predicting the occurrence of strong rockbursts in mines. Both the kinetic theory of solid strength and the “rigid inclusion” model form the basis of this technique. The proposed precursor characteristics of the strong rockburst preparation process, when applied in retrospect to the North Ural Bauxite ...

Studies for rockburst prediction in the Carrara Marble (Italy)
2010The exploitation of Carrara Marble dates back to Roman times. Throughout these twenty centuries, quarrying activity was mostly developed in the Carrara district in open pit quarries. In the last decades many quarries have been moved into underground. In some areas the mining stopes are subjected to rock burst. In order to overcome this hazard, detailed
