摘要
通过对巷道围岩破坏机理以及软岩巷道的特征分析,提出了一种合理的软岩巷道支护形式,详细介绍了可缩性圆形支架与壁后注浆技术的工艺过程,经过实际应用,取得了显著效果。
Based on the failure mechanism of surrounding rock and characteristics of soft rock roadway, the reasonable soft rock roadway supporting forms is raised and the technology of retractable arch support and back - filled grouting are introduced in detail and marks that the result has been achieved after practical application.
