Study on mining deformation and fracture response mechanism and rock pressure law of super thick composite key roof

Abstract In order to study the movement and deformation law of the super thick composite key layer overlying the stope. Taking the geological conditions of Yima mining area as the background, a three-dimensional (3.6 m × 2.0 m × 2.0 m) three-dimensional model was built for testing, and the deformati...
