摘　　要：深部铜矿自1987年投产以来,随着开采深度的不断下降,巷道高地压现象明显,局部处于破碎带区域的分段运输巷道尤为突出,成巷不久随即产生片帮冒顶,严重威胁现场作业人员安全,制约采准、备采矿量按期形成,影响采场衔接。在以往支护方式出现“水土不服”支护效果不佳的情况下,结合现场实际提出的应对措施取得了一定的效果。Since the deep copper mine was put into operation in 1987,with the continuous decline of mining depth,the phenomenon of high ground pressure in the roadway is prominent,especially in the section transport roadway located in the region of crushing zone.Shortly after the formation of the roadway,the roof collapse of the sheet wall occurs,which seriously threatens the safety of the site operators,restricts the timely formation of mining approval and reserve,and affects the connection of stope.In the case of the poor effect of the previous support method,according to the actual situation,the corresponding measures are put forward and some results are obtained.
