摘要
本文对软岩巷道底臌的机理进行了系统的分析，提出了“松动爆破与打封混凝土底拱”治理底臌的方法和原理，并介绍了在铁法三台子一井进行现场试验的一般情况。根据流变力学理论对治底后巷道底板的稳定时间进行了预测。
aving systematically analysed the mechanism offloor heave of roadways in soft rock, the paper broughtforward the method and theory of loose blasting andcasting concrete invert arch to overcome the floor heave,and introduced the engineering case of Santaizi shaft No. 1at Tiefa where the above mentioned method had b een used.Besides, the tim e becoming stablewas also predictedaccording to the rheological mechanical theory.
