The common failure characteristics are summarized to roadways under the impact of fracture zones based on the field investigation of the east area of a newly developed mine. And the subject lies on a -120 main return airway at the east area of the mine. First the failure processes of roadways without supporting and roadways with bolt-and-mesh supporting are presented with the aid of a numerical simulation software, then the study goes to the deformation and failure mechanism of soft rock roadways under the impact of fracture zones, and last why soft rock roadways fail under fracture zones attributes to: high existing stress, low rock mass strength, and large deformation of original supporting that is not suitable for plastic rheology. It lays a solid foundation for the tailored stability control of soft rock roadways under the impact of fracture zones.
