结合潘谢矿区谢桥矿综采工作面具体条件,采用现场实测的方法,对综采工作面回采巷道围岩变形规律进行了研究,得出了综采工作面动压巷道围岩变形规律。研究表明,受采动影响的范围为工作面煤壁前方40~55m处,此范围内的回采巷道围岩顶底板移近量和两帮移近量比较明显,两帮变形较大。
Combined with the specific conditions of the fully mechanized mining face in Xieqiao Mine of Panxie Mining Area, the deformation law of the surrounding rock in the mining gateway of fully mechanized coal mining face was studied by on-the-spot measurement. The deformation law of the surrounding rock of dynamic pressure roadway in fully mechanized coal mining face was obtained. The study shows that the range influenced by mining is 40 ~ 55m in front of the coal wall of the working face. Within this range, the approach amount of the top floor and floor of the surrounding rock in the mining roadway and the amount of two approaches are more obvious, and the deformation of the two gangues is larger.
