Abstract: Aiming at surrounding rock deformation of mining roadway in working face, this paper takes Dashucun coal mine of Fengfeng Group of Jizhong Energy as the research background.By means of theoretical analysis and on-site monitoring, this paper reveals the deformation regularity of roadway surrounding rock in mining face, expounds the main influencing factors of surrounding rock deformation, and deeply explains the mechanics mechanism of roadway surrounding rock change combined with mechanics property experiment of coal mass.The results show that the superposition of in-situ stress and mining-induced stress accelerates the process of damage, deformation and failure of coal mass, and increases the deformation of surrounding rock.Besides, under the influence of extrusion force, the deformation of central symmetrical point of roadway section is the largest, and the surrounding rock deformation regularity of roadway is the most obvious.In addition, periodic weighting is the main influencing factor of surrounding rock deformation in roadway.The nearer to the working face, the greater deformation of surrounding rock.The increase of confining pressure changes the mechanical properties of surrounding rock of coal mass to a certain extent, increases the deformation amount of surrounding rock, and changes the deformation rate and regularity of surrounding rock.
