摘要
肖家洼煤矿211304工作面材料巷迎压掘进,受到相邻211303综放工作面采空区动压影响,巷道出现顶板下沉、底鼓、煤柱鼓帮现象。采用综合治理方法,巷道围岩变形基本趋于稳定,效果明显,为类似条件巷道围岩变形综合治理提供了借鉴。
The material roadway in 211304 working face of Xiaojiawa Coal Mine is affected by the dynamic pressure of the goaf in the 211303 adjacent fully-mechanized working face, and the roof subsidence, the floor heave and the coal pillar deformation appear. By adopting comprehensive treatment method, the deformation of surrounding rock of roadway tends to be stable basically and the effect is obvious, which provides a reference for comprehensive treatment of deformation of surrounding rock of roadway under similar conditions.
