Surrounding Rock Stability Control Technology of Roadway in Large Inclination Seam with Weak Structural Plane in Roof

The surrounding rock control technology of mining roadways in large inclination seams with a weak structural plane the roof is one most challenging fields underground roadway support. In view serious deformation transportation 1201 working face mine, and failure characteristics instability mechanism are analysed. self-stability mechanical model block structure under support effect established, concept “high pre-stressed asymmetric” combined method bolts, wire mesh, cables proposed. rationality supporting scheme verified by numerical simulation. results show that: compared bolt mesh support, maximum shear displacement roof’s layer bolt, meshes, cable before after reduced 86.78% 83%, respectively, total surface 49.22% 37.1%, respectively. field monitoring that can effectively rock.
