摘　　要：针对南山隧道穿越煤系地层和采空区时,发生围岩大变形及采空区塌陷,从设计、施工及地层岩性等方面分析了围岩变形机制,根据围岩变形和采空区实际情况,分别采取相应的处治措施,取得了良好的治理效果。Aiming at the large deformation of the surrounding rock and the collapse of Nanshan tunnel through the coal strata and the goaf,the deformation mechanism of surrounding rock was analyzed from the aspects of design,construction and stratigraphic lithology.According to the deformation of the surrounding rock and the actual situation in the goaf,the corresponding treatment measures are taken respectively and the good governance effect is obtained.
