摘　　要：矿山深井地压大,造成一些巷道支护结构严重破坏,需对原有的支护形式进行改进。结合朱仙庄矿区典型巷道工程,在实验室完成高地压作用下不同材料模型的对比试验,研究模型结构变形、破坏规律和承载能力。通过室内试验的结果,改善支护结构,提出应用复合锚网支护技术来进行巷道的治理。工业性试验证明,复合锚网支护技术能够适用地质条件恶劣、巷道围岩严重变形情况下的支护要求。。Mine deep ground pressure,resulting in some of the support structure of tunnel seriously damaged,need to improve the original supporting form.In combination with Zhuxianzhuang typical mine tunnel engineering,contrast test of different material under the effect of high pressure are finished by using the simulation,the deformation,destruction law and bearing capacity are researched.According to the results of laboratory test,the supporting structure is improved,the composite anchor net support technology to repair the tunnel is designed.The industrial tests have demonstrated that composite anchor net support structure could meet the support requirements in the environment of poor geological conditions and severe deformation of surrounding rock.
