控制软岩回采巷道底鼓的试验研究

Testing on controlling floor heave of soft rock roadway

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。

Abstract The paper analyzes the mechanism using standing shot to control floorheave and proposes the basic principles designing standing shot at the deepinternal of floor. In comparison with the above, the in-situ observationresults are discussed. The research indicates that inducer shotfiring thedeep internal of floor is an effective method to control floor heave of softrock gateway. The main conclusions provide a good reference and guidance fordealing with similar floor heave problems.
