Abstract: This paper takes the water-rich fault roadway of Jining No.3 coal mine as the engineering background, analyses the deformation and damage mechanism of the roadway through on-site investigation and drilling peeping, accordingly proposes the "curtain grouting + grouting anchor cable" joint support scheme, and carries out the on-site practice. The monitoring results show that under the optimised support scheme, the maximum values of the relative displacement of the top and bottom plates and the convergence of the two gangs are 35 mm and 25 mm respectively, and the deformation of the surrounding rock is effectively controlled to ensure the safety of the roadway excavation.
