Abstract: In order to solve the stability control problems of roadway roof in very contiguous seams, the article analyzed the physical characteristics and support features of 5101 roadway surrounding rock, proposed the method of combined supporting with full-size grouted bolt mesh and beam and studied the mechanism of all kinds of support members, reproduced the support effect of the program based on numerical simulation, and further validated the feasibility of research results through the engineering application. The results showed that the fractured rock roof's resistance to cracking and shear capacity was improved after full-size grouted bolt supporting, and its tensile strength and flexural stiffness was increased after metal mesh and anchor roof beam supporting, the rigid support and flexible retaining joint action and their supporting performances were fully played; the simulation results show that roof rock around 0.6 m lower roadway remained stable in mining process; field test found the distance of two sides and roof and floor were 58 mm, 46 mm and 168 mm, 152 mm during drifting and mining, the roof stability of 5105 roadway was well controlled.
