Abstract:

Based on the surrounding rock conditions of deep mine Roadway with Composite Roof, and the results of geo-mechanical on-site tests, combined with Existing bolting-support theories and Numerical calculation results, the Scientific and rational design method and supporting principles were determined. It was proved that the high strength bolting system can effectively reduce the deformation and destruction of roadway with composite roof in deep mine. The supporting system laid the great foundation for the coal mining face fast and safely recovery.

Key words: supporting system with high strength, deep mine with high stress, composite roof, supporting design and application
