摘要
矿井深部近距离煤层开采中,常由于采煤工作面跨巷道开采,下方巷道压力显现大,造成巷道变形及支护破坏严重,威胁着矿井的安全生产。文章介绍了近距离煤层采动影响下的巷道支护设计与支护效果监测。该支护设计方法可以在同类的特殊地点应用。
In mining the near- range seam in the depth of mines, the coal face is mined across roadways, the pressure of down roadways is large. So the roadways deformation and support destroying are serious. The safe production is seriously threatened. The roadway surpport design and effect monitor method under mining stress of near-range seam are introduced. It can be used on the homogeneous and special place.
