The evaluation on compressive strength of tectonite roof according to logging data

    Graphical Abstract
    • Abstract
  • The roof of the 2 1 coal seam in Gaocheng area of Dengfeng Coal Field is constitute of tectonite rock formed by gliding.Based on the research of the relation between logging curves and compressive strength of the tectonite rock,this paper reveals that the dynamic properties of soft rock mass measured with logging technique.
