| Abstract: | Using the methods of equivalent material model test, this paper studies the laws of roof movement in suspensive-advancing support caving mining in the thick coal seam with gentle dip angle in Daanshan coal mine of Beijing coal mining Administration, preliminarily summarizes the laws of roof movement and ground behaviors The studies provide an important basis and direction role for determination of the rational plan and safety technical measures in caving mining. |
