Abstract：The influence of multiple kinds of matching of tectonically controlled fissures and the roadway layout on the stability of mining roadway were studied. The effects of fissure spacing(I)，the inclination of fissure，the angle of the fissure bearing with the roadway axison the convergence deformation of the roadway surrounding rocks were analyzed. And the layout principle of matching of fissure and roadway axis for guaranteeing the stability and maintenance of the roadway under the condition of technically controlled connected fissures was proposed.
