摘　　要：2302进风巷在施工过程中,发现部分已掘巷道压力显现明显,变形较大,无法满足安全和生产需要,通过采取锚注加固技术修复后,保证了巷道安全稳定,实现了2302工作面顺利回采。During the construction process of the 2302 wind drift,there was significant pressure found on the roadway,and there were large deformations,so it was unable to meet the needs of safety and production.After the bolt and grouting reinforced technology was adopted,the safety of the roadway tunnel was guaranteed so that it achieved the smooth mining of the 2302 working face.
