Research on the mechanism of asymmetric deformation and stability control of near-fault roadway under the influence of mining

• The formula of deviator stress of circular roadway in non-uniform stress field is derived. • The variation law of deviator stress and plastic zone with the size and direction of principal stress is studied. • The mechanism of asymmetric deformation failure of near-fault roadway was studied. Aiming at the asymmetrical deformation of the roadway under the influence of geological structure and mining activity, a combination of theoretical...
