告成煤矿25变电所同时处于F141、F135正断层中间,在受到构造影响的同时,还受到其附近的13211辅助巷掘进影响,针对以上条件研究了构造应力场以及巷道开掘等对其围岩稳定性的影响。13211工作面开挖后,变电所塑性区明显增大,顶、底板浅部不同深度围岩体均出现剪切破坏区域,顶、底板变形明显,两帮变形较小。 At the same time, Gucheng Coal Mine 25 Substation is also located in the middle of F141 and F135 normal faults. Affected by the tectonics, Gucheng Coal Mine 25 is affected by the excavation of 13211 auxiliary lane nearby. According to the above conditions, the tectonic stress field, Sexual effects. After the excavated face of 13211 working face, the plastic zone of substation increases obviously, and the surrounding rock mass of the top and bottom shallow sections have the shear failure area. The top and bottom plates deform obviously, and the deformation of the two sides is small.
