| description | Aiming at the problem of large-scale deformation of the track and alleys in the East Second Mining Area, the numerical analysis method is used to analyze the stress and deformation law of the roadway. The results show that the critical depth of the roadway deformation is 800m, the shear stress of the deep roadway is about 8.7MPa in the left and right shoulders, and the vertical stress increases sharply in the range of 0~5.5m from the center of the roadway, and is 6~ from the center of the roadway. The peak value is reached within 8m, the plastic zone of the roadway roof is 2.6m, the left and right plastic zones are 5.2m and 5.4m, respectively, and the plastic zone of the floor is 6.1m. This result can provide a basis for the design parameters of deep soft rock roadway support. The engineering practice proves that the support design effectively controls the strong deformation of the roadway and achieves better support effect. |
