近年来,随着矿井深度的不断增加,底鼓现象已成为软岩巷道与弱结构巷道围岩变形和破坏的主要特征与形式之一,为了控制软岩巷道底鼓,本文分析了动压及软岩巷道底鼓的成因,依据工程实例,来阐述巷道底鼓的变化规律及顶板和两帮对巷道底鼓的作用,并提出了针对锚网索支护对巷道底鼓变形的影响。文章为巷道的支护和底鼓的治理提供了依据。

In recent years, with increasing depth of min-ing, kick drum phenomenon has become one of the main fea-tures in the form of soft rock tunnel with weak structure roadway deformation and destruction, in order to control the soft rock roadway floor heave, the article analyzes the dynamic pressure and causes of soft rock roadway floor heave. By engineering ex-amples, this paper illustrates the variation of the roadway and the top and bottom of the drum on the floor heave between two roles, and made for the anchor net support on the floor heave deformation affected. This paper provides basis for roadway sup-port and the bottom drum control.
