摘 要:为有效解决山西三元煤业股份有限公司4326回风顺槽掘进期间DF1大断层影响区巷道围岩支护的问题,通过理论分析、数值模拟以及现场实测的方法,分析掘进巷道断层影响下巷道围岩的应力环境,探究4326回风顺槽巷道围岩塑性区分布与围岩变形特征,提出4326回风顺槽的加强支护方案与加强支护建议,经现场应用,4326回风顺槽顶底板移近量约120 mm,两帮移近量约150 mm,巷道变形量较小,取得良好的应用效果。In order to effectively solve the problem of roadway surrounding rock support in DF1 large fault affected area during the excavation of 4326 return air roadway in Shanxi Sanyuan Coal Industry Co.,Ltd.,the stress environment of roadway surrounding rock under the influence of fault was analyzed by theoretical analysis,numerical simulation and field measurement.The distribution of plastic zone and deformation characteristics of surrounding rock in 4326 return air roadway were explored,and the strengthening support scheme and strengthening support suggestions of 4326 return air roadway were put forward.Through field application,the displacement of roof and floor of 4326 return air roadway was about 120 mm,the displacement of two sides was about 150 mm,and the deformation of roadway was small.Good application results have been achieved.
