    Graphical Abstract
    • Abstract
  • The distribution characteristics of stope support pressure in different key layers were studied by using physical similar simulation experiment, it was analyzed and obtained that the influence area of advance support pressure was divided into some parts with working face advancing, which included violent area, influenced area, uninfluenced area by the mining. The support pressure of goaf floor decreased obviously with coal mine mining, the pressure relief area expanded. The support pressure peak value, peak position and influence area were influenced by main key layers.
