Failure Mechanism and Control of Roadway Surrounding Rock in Tectonic Development Fault Zone

Taking return air roadway of Yuandian No.1 Mine in 103 mining area as the research object, we simulated the failure characteristics of roadway surrounding rock of geological tectonic development fault zone by FLAC^3D, also analyzed the control characteristics of three different schemes: " deep-shallow coupling control "， " deep-shallow coupling + bottom section control " ，"the whole section control + deep-shallow coupling". The results show that "the whole section control + deep-shallow coupling" can more effectively control deformation and failure and achieve the ideal effect; according to the development degree of the geological structure, a reasonable choice of "bottom section control + deep-shallow coupling" will get more obviously economic effect.
