摘　　要：针对顾北矿11-2胶带机下山严重底鼓的问题,通过对该矿底鼓发生机理分析,围岩物理力学分析以及破坏区围岩应力分布情况分析,得出底板围岩特性、水理作用、支护结构强度是该矿底鼓破坏的主要影响因素,确立了底板锚注的底鼓控制方案。通过后期现场监测和变形参数分析可知,底鼓变形得到有效控制并取得了良好的加固效果。Aiming at serious floor heave problem of Gubei Mine 11 - 2 belt conveyor downhill, by analyzing the mechanism of floor heave of the mine, the rock mass physical mechanics analysis and stress distribution analysis of surrounding rock damage area, it con- cluded that floor characteristics of surrounding rock, hydrological effect, strength of supporting structure were the main influencing fac- tors of floor heave damage. The study determined floor heave control scheme of bolt. Through field monitoring and analysis of deforma- tion parameters, it effectively controlled deformation of floor heave, and achieved good reinforcement effect.
