摘要
软岩巷道底臌防治技术是软岩巷道支护中的一项技术难题。陕西彬长矿区大佛寺矿在对矿井大巷底臌机理进行分析的基础上,提出了底角锚杆+底板注浆+底板锚索耦合支护技术方案,在实践中取得了良好的支护效果,为软岩巷道底臌防治提供了宝贵的经验。
The prevention and control technology of soft rock roadway foor heave is a technical problem in soft rock roadway support. In this paper, based on the analysis of the mechanism of the soft rock foor heave, Shaanxi Dafosi Mine in Binchang mining area put forward the corner bolt ＋ foor grouting ＋ foor anchor coupling support technology scheme, which achieved good supporting effect, and provided a valuable experience for the prevention and control of soft rock roadway foor heave.
