摘要
Abstract
In mine roadway excavation, when roof breakage phenomenon occurs, cementation of roof rock stability is poor. If reasonable and effective support measures are not taken in time, not only the drivage efficiency will be reduced, but it's also easy to cause massive leak roof, even major coal mine safety accident. When the drivage roadway passes through the fault fracture zone, we proposes to take "grouting + round steel brackets" combined supporting method for maintenance of the broken roof, and has achieved a remarkable success.关键词
