Analysis on Geological Features and Influence of Dadikan Tunnel 1 Passing Coal Mined-out Area |
| |
| Abstract: | Dadikan Tunnel 1 on Chengdu-Guiyang High-speed Railway that is under construction passes the coal mine within the coal mining zone in the northeast of Yunnan. The distribution and scale of the coal mined-out areas play a role of control on the line scheme. Therefore, based on the detailed investigation and study of these areas’ distribution, production and surface deformation, the boundaries of the coal mined-out areas and the caving zones were defined by means of measurement, prospecting and drilling, thus where the line heads for was confirmed. In addition, the advises were suggested about safety in the railway construction and operation. |
