摘要
-648m南翼轨道大巷由于布置在软岩中,岩性差、强度低,小断层和褶曲较发育。原设计巷道采用单一锚网支护,效果不理想,巷道变形严重。针对该状况,提出了以"锚网+架棚+注浆","三位"一体的支护技术方案。不仅保持了巷道的稳定。
Due to-648m Nanyi-rail roadway is arranged in the soft rock,lithology is poor and intensity is low with small fault and fold grow.The original roadway design adopts single anchor nets support the effect is not ideal and the deformation is serious.In this situation,puts forward ＂anchor nets with shed and grouting＂,＂three＂ integrated support technology,which not only maintaine roadway stability,but also reduce the roadway repair.
