Surrounding Rock Deformation Characteristic and Supporting Technology of Roadway With Hard Roof

Taking fully mechanized working face mining gateway of Qiling Coal Industry as an example, the paper uses FLAC^3D numerical software to analyze the yield failure characteristics of surrounding rock, the vertical surrounding rock stress and the roadway surrounding rock displacement characteristics respectively during tunneling, it concludes the best gateway support way and supporting parameters under the condition of the hard roof, and they are applied to the engineering practice successfully.
