摘要
Abstract
In the process of excavation, the roadway is likely to meet with fault structural belt, in which the roof will be broken and partial roof caving will arise, thus increases the difficulty of roof support, reduces the drivage efficiency. If reasonable effective measures are not taken in time to control the roof, it is easy to cause large area roof caving accident. To solve this technical problem, Yungang mine, in its construction of 311 belt of 12 # layer311 panel, first analyzed the roof support of the 311 belt lane overcrossing the F8 fault fracture zone, then decided to adopt artificial methods to control and broken roof, which can ensure that the stability and safety of broken roof.关键词
