摘要
为了提高巷道使用安全性,针对1506巷顶板淋水问题,对顶板淋水原因以及围岩结果进行分析,提出采用注浆封堵方式来避免顶板淋水,并详细对注浆封堵施工技术参数进行设计。现场应用后,顶板淋水问题得以彻底解决,注浆浆液充填围岩裂隙效果较为明显,封堵后1年时间内顶板未再出现淋水问题。
In order to improve the safety of roadway use,aiming at the problem of roof sprinkling in 1506 roadway,this paper analyzes the causes of roof sprinkling and the results of surrounding rock,and puts forward the method of grouting plugging to avoid roof sprinkling.The technical parameters of grouting plugging construction are designed in detail.After field application,the problem of roof water leaching can be solved thoroughly,the effect of grouting slurry filling surrounding rock fissure is obvious,and the roof water leaching problem does not appear again within one a after plugging.
