The mining conditions of Lijiahao Mine 3-1 coal seam 12108 working face was taken as the engineering background, the comprehensive use of roof borehole observation, multi base point of displacement monitoring, the surrounding rock loose damage range measurement method were used to deeply understand roadway surrounding rock deformation and failure characteristics, on the basis of this, 4 kinds of optimization of roadway support scheme was put forward, through calculation method by using numerical simulation, considering the economic benefits, optimal recovery roadway supporting scheme influenced by first mining influence and second mining influence were put forward, which provided a basis for the shallow buried thin bedrock roadway support parameter selection.
