摘要： 分析了切眼宽度和顶煤厚度对端头悬顶稳定性的影响，提出了以螺纹钢锚杆锚固为“小结构”、以桁架锚索锚
固为“大结构”的支护方式，并在云冈矿4101 工作面进行了实践应用，保证了大断面端头悬顶的稳定性。

Abstract: This paper analyzed the influence of the width of the incision and the thickness of the top coal on the stability of the
end suspension roof, proposed the support method of taking the deformed steel bars bolt anchoring as the "small structure" and
truss anchor wire anchoring as the "large structure". It has been applied in the 4101 working face of Yungang Coal Mine to
ensure the stability of the large-section end suspension.

Key words: large-section; end suspension; support technology; truss anchor wire
