【摘要】 冲击地压是煤矿开采工程中最为严重的动力灾害之一,且随着煤炭资源开采深度的增加,冲击地压的矿井数量和危害程度呈明显上升趋势,严重威胁煤矿的安全生产。冲击地压的孕育和发生过程中影响因素多且机理复杂,是岩石力学和采矿工程领域研究解决的科学难题。论文以板块构造理论和地质动力学为基础,综合运用理论分析、实验测试、数值计算等研究方法,分析了长沟峪井田地质构造背景和构造演化,划分了构造体系,查明了矿井动力显现的分布特征；基于地质动力区划对长沟峪煤矿区域地质构造形式划分及板块构造与矿井工程实践联系的地质构造模型建立的基础上,通过井下地应力测量和计算,分析区域构造应力场的分布特征,划分构造应力区,确定长沟峪煤矿具备产生冲击地压的应力条件；通过对冲击地压的能量分布特征研究,建立冲击地压动力系统模型,揭示动力系统的能量与系统尺度关系,确定长沟峪煤矿具备产生冲击地压的能量条件。研究成果在长沟峪煤矿的应用表明,长沟峪区和安子区具备发生冲击地压的动力背景和地质构造条件,揭示了地质构造对冲击地压的控制作用,为长沟峪煤矿冲击地压的预测与防治提供了理论基础和科学依据,对保证矿井安全生产具有重要意义。更多还原

【Abstract】 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.更多还原
