Study On Tectonic Stress And Dynamic System Effect On Rock Burst Of Coal Mine

Rock brust is one of the most serious disaster in coal mining project, and with the increasing of mining depth of coal resources, rock brust and the number of mine hazards are clearly on an upward trend, threatening the safety of coal mines seriously. Rock brust is revealed inoculation and complicated mechanism and influence which during its gestation and the occurrence, and it also the scientific problems in rock mechanics and mine engineering research field.Papers as the basis theory of plate tectonics and geological dynamics, integrated use of theoretical analysis, experimental testing, numerical calculation method. Through analysis of the Minefield changgouyu tectonic setting and tectonic evolution, divided tectonic system, identifying mine power distribution characteristics appeared; Use of the geological dynamic division divided form of regional tectonics changgouyu mine, and to identify the active faults at all levels of activity and control of rock burst, to esTab.lish tectonic plate tectonics mine engineering practice model,the esTab.lishment of the geological structure of the plate tectonics mine engineering practice model; through underground situ stress measurement and calculation, analysis of the distribution characteristics of the regional tectonic stress field division of tectonic stress, determine the coal mines have changgouyu produce mine Dynamic apparent stress conditions; By of rock brust characteristics of the study show the energy distribution, the esTab.lishment of the power system model reveals energy system scaling relations of power system, determine changgouyu mine has generated the energy conditions of the rock brust.The research results of Changouyu mine show that Changouyu area and Anzi area have dynamic background and geological structure condition of rock brust, and the control effect on geological structure to mine rock brust has been reveals, which provide the theoretical basis and scientific basis for rock brust prediction and prevention of Changouyu mine and has significant effect to ensure mine safety production.
