摘要
为了对不稳定巷道围岩进行加固,采用综合加固技术,主要包括巷帮预注浆、起底刷帮、围岩喷浆封闭、帮顶预应力锚索补强等技术,并研究了巷道底鼓的防治措施及注浆系统和安全措施。研究结果能够为不稳定巷道的支护提供技术支持。
In order to strengthen the surrounding rock of unstable roadway,this paper adopted comprehensive reinforcement technology,which mainly included pre-grouting of roadway side,bottom brushing,surrounding rock shotcreting and reinforcement of top prestressed anchor cable,the prevention and control measures,grouting system and safety measures of roadway floor heave were also studied.The research results can provide technical support for the support of unstable roadway.
