摘要：

This paper takes the right third pre-mining roadway of Double-river Coal Mine as the research object. Based on the analysis of the deformation law of soft rock broken roadway, a composite support technology scheme combining one-time reinforcement support and surrounding rock grouting reinforcement scheme is proposed. The application shows that the deformation of the composite support roadway is significantly lower than that of the conventional support roadway used in the same environment. The deformation of the roadway is effectively controlled, which greatly reduces the amount of repair and maintenance of the roadway, and achieves safe mining of the working face.
