摘要
针对3102工作面辅运顺槽底鼓严重的问题,采用理论分析、数值模拟、现场实测的方法研究了巷道底鼓机理,认为该巷道的底鼓类型属于包括挤压流动性与挠曲褶皱性的复合型底鼓。提出采用超挖锚固回填+底角锚杆的方法控制底板。
For the problem of serious floor heave of 3102 working face auxlhary transport roadway,me floor heave mechanism was studied by the theoretical analysis, numerical simulation and field measurement method. The floor heave types mainly belonged to compound floor heave include liquidity squeeze and flexure fold. Using over-excavation anchoring and backfilling and corner bolt to control floor was put forward.
