摘要
为了合理确定支护方案和支护参数,解决矿井深部区域支护效果差、巷道易变形难题,针对平煤股份一矿-517m丁戊组石门岩体破碎软弱,具有持续变形特点和围岩流变特性,在提出科学控制巷道流变机理基础上,选择"锚网索支护+喷浆+导管注浆+集束锚索注浆"等联合控制围岩加固技术对其进行修复。实践证明,该支护方案能够解决流变围岩巷道变形问题,保证了巷道断面和正常使用。
In order to determine a reasonable supporting scheme and supporting parameter, solve the problem of poor supporting effect and easy deformation of roadway in deep mine, for the-517 m Dingmao Shimen of No.1 Mine rock mass broken and weak, characteristics of continuous deformation and rheological properties of surrounding rock, based on the scientific control of roadway rheology, ＂bolt mesh cable branch support ＋ gunite ＋ duct grouting ＋ cluster anchor grouting＂ joint control of surrounding rock reinforcement technology is selected to repair it. Practice has proved that the support scheme can solve the problem of the deformation of roadway surrounding rock roadway, and ensure the roadway section and normal use.
