摘要
袁庄煤矿Ⅳ1专用回风道受永久煤柱支承压力影响,巷道变形十分严重。研究从提高巷道围岩强度和支护结构稳定性出发,针对巷道的破坏特征,提出了耦合支护技术方案,并得到成功应用。
Ⅳ1special air return way of Yuanzhuang Mine is influenced by supporting stress manent pillars, so the deformation situation is very serious. To the failure features of roadways, the from strength of surrounding rocks and stability of supporting structure, presented the coupling The successful application has been achieved.
