Description	Journal: Iop Conference Series: Earth and Environmental Science Based on the on-site investigation and monitoring of the working face of Yannan Mine I0128203, by using FLAC 3D numerical simulation software, the mechanism of deformation and instability of roadway surrounding rock is analyzed, and it is concluded that the existing support method has been unsuitable for the soft rock roadway and technical requirements. Aiming at this problem, propose a new technology of hollow grouting anchor support. The support parameters and support process are optimized through field experiments. The results of mine pressure observation show that the technology has achieved the goal of maintaining roadway stability.
