针对五阳煤矿02工作面回风巷道底鼓控制难题,采用现场观测、理论计算、数值模拟和现场工业性试验相结合的方法,研究巷道底鼓的变形破坏特征,提出底板“钻孔卸压”和“加固支护”方案进行底板控制,底板变形量为90~120mm,巷道底鼓控制效果良好,能够保证巷道的安全使用。

In response to the difficult problem of controlling the heaving floor of the return air roadway in the 02 working face of Wuyang Coal Mine, a combination method of on-site observation, theoretical calculation, numerical simulation, and on-site industrial testing is adopted to study the deformation and failure characteristics of the roadway heaving floor. A floor "drilling pressure relief" and "reinforcement support" scheme is proposed for floor control. The deformation amount of the floor is 90-120 mm, and the control effect of the roadway heaving floor is good, which can ensure the safe use of the roadway.
