为研究巷道发生底鼓的机理,采用理论分析、模拟实验等方法,分析了底板岩层结构与物理性质、围岩应力状态、开采扰动、水理作用、支护结构等5种因素对巷道底鼓的影响,研究了一般巷道底鼓和动压巷道底鼓机理。基于此,提出复杂条件下巷道非线性、突变性、强动力性的底板岩层破坏演化及应力分布规律、巷道底鼓预防与治理时机是未来底鼓治理研究的重点。
In order to study the mechanism of the bottom drum in the roadway, the paper analyzes the structural and physical properties of the floor rock, the stress state of the surrounding rock, the disturbance of mining, the action of water, the supporting structure and so on, The influence of the general tunnel bottom drum and dynamic pressure roadway bottom drum mechanism. Based on this, the evolution and stress distribution of floor rock under non-linear, abrupt and strong driving force are proposed under complex conditions. The prevention and treatment timing of road bottom drum is the focus of future research on the management of bottom drum.
