摘要:
针对神东矿区大柳塔煤矿采用7.0 m采高综采面回采5-2煤三盘区时回采巷道出现不同程度的变形破坏现象，采用现场实测的方法对52304及52303工作面回风顺槽之间的区段煤柱进行了巷道变形及应力变化规律的监测，并运用FLAC3D数值模拟软件对不同埋深条件下两工作面之间区段煤柱的应力分布规律进行了模拟，最后总结分析了回采巷道变形破坏的机理，并得出采空区段煤柱的失稳是造成回采巷道变形破坏的根本原因。从而为巷道的合理布置及相应控制对策的提出提供基础数据，以保证矿井安全高效的生产。
Abstract:
The mining gateway has appeared the phenomena of deformation and failure with different degrees when adopting the fully mechanized face with 7.0 m mining height to mine three panel zone of 5-2 coal seam in Daliuta Coal Mine of Shendong Mining Area, so the field measurement method was used to monitor the roadway deformation and stress variation laws of the section coal pillar between the air-return way of 52304 and 52303 working faces. The laws of stress distribution for the section coal pillar between two working faces under different conditions of buried depth was simulated by using FLAC3D numerical simulation software. Finally, the mechanism on deformation and failure of mining gateway was analyzed. It showed that the instability of coal pillar in the goaf section is the basic reason for the deformation and failure of mining gateway. It provides basic data for the reasonable layout of roadway and the corresponding control measures, so as to ensure the safe and efficient production of mine.
