Abstract
In order to study the deformation failure laws of the roof gas tail roadway,combining with the geological conditions of the 7605 high gas fully mechanized caving face in Wuyang mine,the physical simulation and FLAC3D numerical simulation were adopted to analyze the characteristics of the stress distribution and the plastical development in the surrounding rock of the roof gas tail roadway and mining roadway.The results indicated that after the face mining sufficiently,a range of 10~16 m stress composited concentration zone was developed in the front of the coal rib,and the maximum concentration factor of the vertical stress is approximately 2.72.with the employment of gas tail roadway control technology,the field trial has obtained good results.关键词
