| Abstract: | During the initial excavation,the tender coal seam workings in deep seam in Nantun Colliery takes on slocking of roof,with breaking-out in bulk coal and surrounding rock failure.Based on the research of this event,the page simulate the failure of surrounding rock under various supporting situation and workings in various position,which is associated with the actual state,to determine the support scheme of deep tender workings: adopted the leading bolting to depress the roof-fall and combined support using anchor bolt and cable anchor as the permanent scheme.By the in-situ measurement,the movement of roof is well controlled. |
