摘要
阐述了厚煤层下层位巷道合理位置的确定方法和布置设计方案,对巷道布置方案进行数值模拟分析,进一步对巷道支护进行了系统的研究。分析认为,当顶板有比较好的强度时,采用单一的全长锚固预应力锚杆进行支护时效果显著,达到设计要求。
This paper expounds the determination method and the layout design scheme of the roadway in the lower layer of thick coal seam,carries on the numerical simulation analysis to the roadway layout scheme,and further carries on the systematic research to the roadway support.The analysis shows that when the roof has good strength,a single full-length anchor pre-stressed anchor is used to support the roof,and the effect is remarkable,which meets the design requirements.
