Abstract: Taking the 3下1001 material lane of Fucun Coal Mine as the research object, throughing observation of the top rock formation of the roadway, and combining the engineering geological conditions of the roadway, the completeness of roadway roof is initially determined and it is affected by the mining damage of the 3上 seam. The factors influencing the stability of the roadway are analyzed in detail. The repair and support method of the 3下1001 material roadways is proposed. On-site construction achieves better results and deformation has been effectively controlled.
