| Abstract: | Rock structure formed of the break of roof rock along the slope in the steep-dipping longwall face is thoroughly analysed. A formula for calculating the internal force between rocks is derived."Unsymmestrical three-articulated arch" structure formed along the slope of roof stratum is drawn. These results of research has a practical significance for roof control. |
