Abstract: Aiming at problems of Xiaotun Coal Mine such as fluvial rock in the roof and floor of roadway, destabilization of water immersed in Gob-Side entry, continuous large deformation of surrounding rock, etc., through the surrounding rock deformation monitoring and pull-out test, the analysis of the surrounding rock under the original support conditions deformation characteristics and causes of damage, and optimization of the support program, two gangs of hollow grouting anchor (anchor) high-strength pre-injection + roof high-strength full anchor + bottom grouting reinforcement support program were proposed. After the joint support scheme with anchor and injection, the displacement of the roadway surface is measured. Reduced by 38%,77%, and 40% respectively. The optimized supporting plan effectively controlled the deformation of roadway surrounding rock and achieved good support effect.
