摘要: 对巷道顶板破坏变形进行了分析研究,深入探讨了深部围岩环境应力和顶板变形特征,分析研究了影响顶板
稳定性的因素。同时,针对巷道顶板稳定性控制提出加长支护锚杆的措施。实践证明,加长支护锚杆能够很好地解决围
岩顶板大幅度下沉的问题,从而提高支护性能。

Abstract: This paper analyzed and studied the roof failure deformation of the roadway, deeply discussed the environmental stress
and roof deformation characteristics of the deep surrounding rock, and analyzed and studied the factors affecting the stability of
the roof. At the same time, the measure to lengthen the support bolts was proposed for the stability control of the roadway roof.
Practice has proved that lengthening the supporting bolt can well solve the problem of the large-scale sinking of the surrounding
rock roof, thereby improving the supporting performance.

Key words: roadway; deep mining; roof deformation; roof stability; control technology
