摘　　要：膨胀性软岩巷道底鼓防治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402采区水仓底板为铝质泥岩,支护困难,在对巷道底板破坏机理进行分析的基础上,提出了底角锚杆+钢筋混凝土反拱支护方案,在大佛寺矿实践中取得了良好的支护效果,为膨胀性软岩巷道底鼓防治提供了宝贵的经验。The prevention and control of bulging soft rock roadway bottom drum is a technical problem in soft rock roadway support. Based on the analysis of the damage mechanism of the roadway floor, Puts forward the scheme of floor corner bolt + reinforced concrete anti-arch support, which has obtained a good support effect in the practice of the Shaanxi Binchang Dafosi mine. It provides valuable experience for the prevention and control of bottom drum of soft rock tunnel.
