In order to reduce the impact of pressure on the hydraulic support and improve its bearing capacity,the coupling model of the hydraulic support is constructed in ANSYS Workbench according to the coupling mode of surrounding rock of the hydraulic support.The probability distribution diagram and sensitivity image of the roof with high stress are calculated through several iterations,so as to obtain the optimal result.The results show that the maximum stress is 194.37 MPa and the maximum stress is reduced by 28.8%.In the positive and negative direction of deformation,the deformation amount decreased by 11.26%and 37.05%,respectively.
