The Influences of Surrounding Rock Deformation in Deep Roadway under Different Supporting Structures
Abstract：With the increasing depth of coal mining, the deformation features of surrounding rock become more complicated. Based on ANSYS numerical simulation software, the deformation situation of the deep surrounding rock is analyzed under four different supporting forms. The research result showed that under 30 MPa original rock stress, the horizontal displacement and vertical displacement of com- bined support were both smaller than the others, influence area of the deformation was also minimum, the combined support was more fit for the surroundinz rock of roadway with worse geologiical condition.
