Abstract: Taking Zhangji Coal Mine 11418 (W) mining roadway as engineering background, the existing support difficulties of larger change of roadway roof lithology and the existence of sandstone fissure water are analyzed. Combined support and the support measures for improving roadway's initial support strength are proposed. Through roadway's load calculation and theoretical analysis, the parameters of roadway are determined, and the numerical simulation results further verify the control effect. The engineering application results show that the control effect of roadway is remarkable.
