In this paper, the deformation and damage characteristics of the surrounding rock of the roadway in different periods are investigated by using FLAC 3D numerical simulation with the facing-mining excavating Roadway of this coal mine as the research background. At 20m ahead of the working face, a discontinuous plastic zone appeared in the surrounding rock of the roadway, and this phenomenon is a plastic zone jumping through due to the different hardness of the lithology. Real-time monitoring of the stability of the roadway is carried out using on-site measurement, and the roadway is affected by a large amount of mining in the 50m point of the working face in front of the roadway. Based on the numerical simulation and on-site monitoring results, the support strength was increased at 50m of the roadway over the working face, and a new support program was adopted. In the lagging section of the roadway, where the mine pressure is strongly manifested, anchor rods and anchor ropes with W steel belts are used to carry out differentiated reinforcing support, and the on-site effect is good.
