摘　　要：为解决曙光煤矿巷道利用率低、采掘接替紧张的问题,设计在该矿的1226工作面首次应用切顶卸压自成巷无煤柱开采技术,依据1226运输巷详细的地质条件设计"切顶卸压+恒阻大变形锚索"留巷支护的相关参数,现场应用过程中监测结果表明,恒阻大变形锚索受载状态良好,巷道断面收敛量控制在合理的范围内,经过简单修复后可以满足断面要求,成功的应用了沿空成巷无煤柱开采技术。In order to solve the problems of low utilization of the roadway of Shuguang Coal Industry and the tightness of mining replacement,it is designed to apply the topless pressure relief self-forming coal pillar-free mining technology for the first time in the 1226 working face of the mine.Relevant parameters for retaining roadway support of"top pressure relief+constant resistance large deformation anchor cable",monitoring results during field application show that the constant resistance large deformation anchor cable is in a good load state,and the convergence of the roadway section is controlled within a reasonable range.After simple repair,the section requirements can be met,and the coal pillar-free mining technology has been successfully applied.
