    Graphical Abstract
    • Abstract
  • On the basis of analyzing the surrounding rock destruction mechanism of Shunhe coal mine main haulage roadway, the best time and secondary supporting scheme to repairing roadway are determined. The roof subsidence, the deformation amount of roadway two sides, the amount of heaving floor and surrounding rock stability are in line with the design and the using requirements.
