煤岩变形破裂,deformation and fracture of coal or rock
1)deformation and fracture of coal or rock煤岩变形破裂
1.Research on the effect of the influence of confining pressure on EME during thedeformation and fracture of coal or rock mono-axial compressed单轴压缩煤岩变形破裂电磁辐射围压效应研究
2.Then according to the stress values and the coupling laws between electromagnetic emission(EME) strength and stress fields during thedeformation and fracture of coal or rock,the changing laws of EME strength during mine tunnel excavation are studied.研究结果表明:模拟应力值的变化规律与理论分析和现场实际围岩应力显现规律是一致的,从而说明该方法能正确模拟现场煤岩受采动影响时内部应力场的变化规律;将较大范围煤岩体单元当作电磁辐射源时的计算结果只比将应力集中区看作电磁辐射源的计算值大3%～8%,说明在现场监测到的EME强度反映的是应力集中区煤岩变形破裂的程度;EME强度在迎头沿着走向符合先逐渐增大达到峰值后再逐渐降低的规律,呈现出与煤岩内部应力变化相同的规律;随着迭代时间的增加,EME强度在同一监测点的变化关系先是逐渐增加,增加到一定程度后趋于平缓,反映了煤岩体内部应力的变化规律;巷道开挖后内部应力变化的快慢表现在EME强度的变化上。
3.On the basis of the relationship between EME signal and loading stress duringdeformation and fracture of coal or rock,the coupling methods between EME and stress are studied based on FLAC simulation for stress field and EME propagation.对煤岩动力灾害电磁辐射预测技术的研究现状和发展趋势进行了论述与分析,基于煤岩变形破裂电磁辐射信号与受载时应力变化之间的关系,从FLAC应力场数值模拟与电磁辐射传播的角度对煤岩变形破裂电磁辐射力电耦合研究方法进行了研究。
