he Project Feasibility Study (FS) has been fully completed, and preparations are currently underway to incorporate public feedback.
Key Parameters of the Ulaanbaatar Metro Project:
Line 1: Tolgoit – Amgalan corridor
Alignment length: 19.4 km
Number of stations: 15
Average interstation distance: 1.3 km
Average operating speed: 36.5 km/h
Capacity: 17,200 passengers per hour
Engineering Geological Investigation:
Borehole drilling was carried out at 42 locations along the 19.4 km alignment, reaching depths of up to 30 meters below ground level. Laboratory testing was conducted to determine soil composition and the deformation modulus. The results indicate that the soil deformation modulus in Ulaanbaatar exceeds 23, which is considered suitable for tunnel construction. Therefore, an Earth Pressure Balance Tunnel Boring Machine (EPB TBM) has been selected.
Hydrogeological Investigation:
Potential risks of encountering groundwater during tunneling were identified, and appropriate groundwater control and drainage measures have been planned accordingly.
