摘要: 为控制A 矿巷道围岩变形,抵抗流变,保持巷道围岩的稳定性,通过矿压监测以及对围岩变形特征的分析,
决定采取“内外耦合支护”的方式进行巷道围岩稳定的控制。试验结果表明,应用该技术后,巷道围岩位移较小,锚杆
受力稳定,并无明显离层出现,软岩巷道得到有效支护,为安全生产提供保障。

Abstract: In order to control the surrounding rock deformation, resist the rheology and keep the stability of the surrounding rock
in A Coal Mine, through the monitoring of the mine pressure and the analysis of the deformation characteristics of the surrounding
rock, it was decided to adopt the method of "internal and external coupling support" to control the stability of the surrounding
rock. The test results show that after applying the technology, the displacement of surrounding rock is small, the stress of bolt is
stable, and there is no obvious separation layer. The soft rock roadway is effectively supported to provide security for production.

Key words: coupling support; soft rock; surrounding rock control
