Abstract: Analysis is made on the mine geological features of targeted area and it is found that the tectonic fissures and their development degree have a great impact on the roadway stability.Model test and numerical simulation are used in combination to study the effect of fissures on the deformation law of roadway wallrock in terms of fissure distribution characteristic, laying a foundation for a quantitative assessment of the deformation and stability of roadway in fissured rock mass.

Key words: Fissured rock mass, Roadway deformation, Simulation test
