摘　　要：根据赵固一矿11001采煤工作面地质条件选择了支护方案,合理设计了11001采煤工作面开切眼的锚网索联合支护参数,并阐述了巷道支护过程中的具体施工工艺。依据现场监测结果,总结了巷道围岩变形规律。实践表明,巷道锚网索支护效果较好,巷道断面符合质量标准。The supporting method was selected based on real engineering geology condition of 11001 working face of Zhaogu No. 1 Coal Mine, the supporting parameter of combined supporting of bolting with mesh and anchor cable was designed reasonably in open-off cut of 11001 working face. Construction technics in the construction process were expounded in detail. According to the results of the field measurement, the laws of deformation of surrounding rock in roadway were summarized. Practice shows that, the supporting effectiveness is preferably ,and the roadway section satisfies the quality standard.
