Abstract: The problem of roadway instability induced by weak surrounding rock conditions is becoming more and more prominent.Under this conditions, the degree of roof caving, rib spalling and plastic failure depth far exceed the general geological conditions, which has seriously threatened the safe operation and efficient production of roadway.Based on the engineering background of G3-1106 transportation gateway in 3# coal seam of a mine in Ordos City, the deformation of weak surrounding rock roadway is studied by means of theoretical analysis, numerical simulation and field monitoring.A combined support scheme of ‘long anchor rod+long anchor cable' is proposed.By using FLAC^3D numerical simulation software, on-site surrounding rock deformation monitoring and borehole peeping, the feasibility and practicability of the optimized support scheme are finally verified.The results show that the characteristics of weak surrounding rock roadway are ‘weak roof, soft coal wall and support loss';after adopting the optimized support of ‘long bolt+long anchor cable',the stability of weak surrounding rock roadway can be increased by 80.9%.
