| 摘 要： | 大倾角煤层回采巷道因处于显著的各向异性环境中而难以维护。本文用离散元法分析了回采巷道的变形破坏机理和形式, 结合现场巷道的围岩松动范围实测, 证实巷道的上帮普遍破坏严重, 是整个巷道破坏的突破点, 应重点防范并采用综合支护进行治理。

| Abstract: | ateway in inclined coal seam is difficult to maintaine mainly due to its location in a remarkably anisotropic environment. The failure and deformation mechanism and pattern of gateway in inclined seam are analyzed by using discrete element method in combination with measurement of loose zone around gateway in field. It is proved that the upper side wall fails seriously and it is the key part to maintain the whole gateway. It is suggested that a comprehensive support pattern must be adopted including sidewall reinforcing. |
