| Abstract: | Based on the periodic rock pressure manifestation in steep longwall stope along the strike and the manifestation characteristics in different districts of stope along the sloping, the rock roof deforming and breaking patterns are analysed by using sloping thin plate and the mechanics model of breaking the main roof rocks is set up. Here gives the analysis on rock movement and equilibrium law under distinct filling conditions. Meanwhile expounds the mechanism of Periodic rock pressure manifestation, in steep seam and Peculiarities of rock strata control. |
