Abstract: We studied stability control of surrounding rock in trapezoid composite roof roadway with the engineering background of strong geological structure in Ningdong Mining Area. The section configuration of the roadway driving along the top in the inclined coal seam is trapezoidal and the exposure width of the roof increases. This condition leads to difficulty of the roadway supporting greatly increasing. The double beam supporting structure model is founded, which takes main roof as the girder and roof composite beam as the joist, and the coupling support theory of double girder and the theory of angle asymmetric in the bolt support in the inclined roof roadway is proposed. In the end, all of these theories passed the engineering verification in the 130202 tunnel.
