Numerical simulation testing research on coupling support of coal roadway under high stress area
Abstract：In order to research the effects of the roadway deformation controlled by coupling support,under the different support parameters,researched the displacement on the roof,the floor,the left,and the right,and the max displacement of the surrounding rock in a coal 11010 working face tailentry by FLAC3D numerical simulation software on the basis of the theory of coupling support.The result showed that the displacement of roadway deep point and the max displacement of the surrounding rock were both small,and the time which was needed to keep stable in the roadway when it was satisfied with the coupling support in between the support bodies and the surrounding rock,and among the support bodies.The engineering case furtherly stated that the coupling support could be effectively controlled the roadway rock deformation,and maintenance the roadway stability.
