Study on Optimization of Roadway Support and Law of Deformation and Failure of Surrounding Rocks with Tectonic Stress in Rectangle Roadway

摘要：

　　Tectonic stress effects on the stability of surrounding rocks of roadway clear,using numerical simulation of axial and angle of maximum horizontal stress rectangle roadway is not the same as law of deformation and failure of surrounding rocks of roadway,indicates that minimal impact for the district,as a growth area,influence violent areas.Axial and angle of maximum horizontal stress of mining roadway in coal mine is 42°,the tunnel roof and two large loose broken,optimization of existing support programs.

关键词： tectonic stress rectangle roadway bolt support surrounding rock deformation
