简要介绍了巷道收敛监测网布设、监测方案以及监测结果，并给出了监测所获得的一些结论。
The arrangement of laneway convergence monitoring net, monitoring project and monitoring result are presented, and some meaningful conclusions are obtained.
围岩处于破裂状态时，巷道收敛主要是由处于残余强度状态的破裂区围岩的碎胀变形引起的。
When the rocks are fractured, roadway convergence is mainly due to expansion deformation of the surrounding rock within the fractured zone in a residual-strength state.
进路开挖以后支护巷道破坏严重，其围岩变形为无收敛变形，也是国内支护较难的矿山之一。
After the roadway was excavated, the destruction of supporting roadway is very severe. The deformation of roadway is no convergence deformation; and the iron mine is difficult support mine.
