Research on Technology of Surrounding Rock Stability of Soft Rock Roadway in High Stress Area
Aimed at productive and geological conditions of Guhanshan western main roadway , the field testing and numerical calculating methods are used to study the impacting law of loose destressing parameters on the plastical zone , the peak value position and the peak value magnitude of the rock stress of soft rock roadway in the high stress area . The rational distressing parameters are determined , and the control technology and the stability principle of soft rock roadway in the high stress area proposed , i.e. the stress peak value of the surrounding rock of soft rock roadway is transferred to the deep level of the surrounding rock , so as to reduce the shallow stress of the surrounding rock . The grouting reinforcement and the bolting with high strength are used to enhance the rock integrity and the rock strength in fracture zones , therby , the stability of the soft rock roadway is realized . This studying result has been successfully applied in the practical engineering .
