| 摘 要： | 本文利用UDEC3.0软件对近距离上保护层开采导致的覆岩移动及裂隙发育过程进行数值模拟。真实地反映了在开采保护层过程中覆岩移动及裂隙发育规律。利用UDEC3.0软件模拟煤层开采引起的覆层移动过程可以预知实际开采中瓦斯运移通道的动态分布,对防止瓦斯突出具有重要的指导意义。

| Abstract: | Numerical simulation was conducted using UDEC3.0 for the movement of overlaying strata and fracture development caused by the mining of upper protective layers of coal seams with close quarters. The results really reflected the law of overlaying strata movement and fracture development. The dynamic distribution of gas migrating Channel during the mining of coal seams can be predicted by the simulation of overlaying strata movement caused by the mining of coal seams using UDEC3.0. This has important guiding significance on the prevention of gas outburst. |
