本文分析了软岩巷道支护研究的国内外现状，以围岩松动圈理论研究为基础，得出围岩松动圈与软岩巷道支护的关系。

Results indicate that the bolt-grouting support helps to increase the strength and bearing capacity of the surrounding rock and to control its deformation effectively.

结果表明，辅助锚注支护显著提高了围岩的强度和承载能力，有效地控制了深部极软岩巷道的围岩变形。

Systematic rock bolt support and shotcrete were carried out for the surrounding rock and reinforcement was done locally for rock stability.

对围岩采用系统喷锚支护，局部作加强处理，稳定性良好。
