中文摘要：

应用现场实测和计算机数值模拟(FLAC3D)方法,研究调整并分析了不同煤柱宽度条件下,综放回采巷道围岩位移分布特征及其变化规律。研究结果表明,护巷煤柱的宽度不同,综放工作面巷道位移变形有很大差异,巷道围岩移动具有明显的采动影响近场效应;在一定的护巷煤柱宽度范围内,并非煤柱越宽越稳定,或在极窄小煤柱护巷条件下,将巷道布置在采空区边缘低应力区就有利于维护;合理的支护方式应能控制巷道采动影响剧烈阶段的围岩变形,支护设计应从载荷控制向变形控制转变。

With the site measurements and the computer numerical simulation(FLAC3D) method,the paper studied and analyzed the surrounding rock displacement distribution features and the variation law of the mining gateway with different coal pillar widths.The study results showed that due to different coal pillar width,the displacement and deformation of the mining gateway would be great difference.The surrounding rock displacement of the mining gateway would have an obvious close distance affect by the mining operati...
