Abstract: Aiming at the existing problems of large deformation,roof collapse and others in the 120710 transportation roadway,through a method of combining indoor experiment and numerical simulation,the ground stress is measured using the hollow inclusion stress relief method.The influence of different top anchor rod row spacings on the stability of the roadway surrounding rock is analyzed,and technical measures to optimize the surrounding rock support parameters are proposed.The reasonable top anchor rod row spacing is quantitatively determined,and the targeted specific support optimization scheme is proposed.After optimizing the support scheme,the relative deformation amount of the roadway is relatively small and the support cost is relatively low,providing a certain reference basis and research foundation for the optimization of coal mine roadway support under similar geological conditions.
