Deformation Mechanism and Treatment Measures for the Surrounding Rock of Nanshan Tunnel passing through Coal Stratum and Goaf |
| |
| Abstract: | 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. |
