针对郑煤集团白坪煤矿深部开采水平13采区胶带机头硐室变形破坏特征,为控制围岩变形量及保证生产安全,通过对硐室原有锚网喷支护破坏进行分析,得出围岩失稳的主要原因,并根据硐室的破坏情况,提出了二次锚网索协同稳定性支护技术,有效地控制了该矿深部硐室围岩变形。 In order to control the deformation of surrounding rock and ensure the production safety, according to the deformation and failure characteristics of the tape chamber of 13 mining area in the deep mining level of the Zhengping Coalfield Baiping Coal Mine, by analyzing the failure of the original bolting and shotcreting support in the chamber, The main reason of surrounding rock instability is that according to the damage of the chamber, the cooperative support technology of secondary anchor net is put forward to effectively control the deformation of the surrounding rock of the deep chamber.
