| 摘 要： | 工作面回采巷道处于煤体中,围岩强度较低,受采动影响较大,围岩变形大,破坏严重,难于支护。针对新胜井+90工作面回采巷道破坏特点,设计了合理的锚杆(索)支护方案,现场实践及矿压观测数据分析表明,该支护方案有效控制了巷道变形,取得了良好的经济效益。

| Abstract: | The mining gateway is in coal,surrounding rock has lower intensity,and its deformation and destruction were serious under mining influence.It is difficult to support.In view of the deformation character of stoping excavation in +90 working face of Xinsheng mine,reasonable bolt(cable) support plan was designed.The field practice and strata pressure observation data showed that gateway deformation was controlled effectively,and the better ecoomic benefit was obtained. |
