本文分析了巷道底板深部松动爆破控制底鼓的机理，提出了底板深部松动爆破参数设计的基本原则，详细分析了现场试验的实测结果。研究表明采用底板深部松动爆破是控制松软围岩回采巷道底鼓的一种行之有效的方法，其主要结论对类似巷道底鼓的防治有较好的借鉴和指导作用。
In this paper, the principle of controlling the bottom drum by deep loose blasting in roadway floor is analyzed. The basic principle of the deep loose blasting parameter design of floor is put forward. The field test results are analyzed in detail. The research shows that the deep loose blasting of the floor is an effective method to control the bottom drum of the soft surrounding rock roadway. The main conclusion is a good reference and guidance for the prevention and treatment of similar tunnel bottom drum.
