| Abstract: | The stability effective law of the mining roadway because of different coupling between controlled tectonic fissures and roadway layout is studied.And the effects of fissure′s spacing,fissure′s inclination and fissure′s coupling angle with roadway trend on roadway around-rock displacement is mainly studied,the coupling principle between fissure′s trend and roadway layout in order to ensure roadway′s stability and maintenance under rock-mass controlled by tectonics fissures is finally put forward. |

| Keywords: | rock-mass cut by tectonics fissure′s coupling with roadway layout roadway stability |
