Abstract:Aiming at the problems of deep location and difficult support of the air intake roadway in 7121 deep-inclined fully-mechanized working face, analysis was made on the stress distribution and deformation characteristics of the roadway surrounding rock after the roadway driving along the gob by using FLAC3D numerical simulation software, and based on the principle of the large and small structural stability of the roadway driving along the gob, the integrate control measures for the surrounding rock and the combined support mode of high-strength cable and mesh coupled system were proposed, which was applied in the air intake roadway in 7121 fully-mechanized working face. The results showed that the deformation of the surrounding rock can be effectively controlled during the roadway driving and coal winning, this thus ensured the safe and high-efficient production of the mine.
