Operational Indicators of the Mine
Total Overburden and Waste Rock: 17.8 million m³
Mining operations, including overburden removal and extraction along the coal seam, are performed using high-productivity machinery and advanced technologies.
Overburden Removal: 15.6 million m³
Overburden stripping is carried out by open-pit methods according to phased mine planning to ensure stable production continuity.
Coal Production: 3.0 million tons
Annual coal production has been steadily increasing, with capacity utilization improving year by year.
Coal Exports: 2.5 million tons
The majority of mined coal is exported as a high-quality raw product, contributing significantly to Mongolia’s export revenue.
Operational Management
Mining operations are conducted in compliance with international standards and strict safety requirements in the following areas:
1. Open-Pit Mining
Extraction is performed using open-pit mining methods, incorporating drilling, blasting, loading, and hauling stages with modern equipment.
Mine planning and phased scheduling are carefully developed based on geological structure.
2. Coal Loading and Transportation
Coal extracted from the mine is transported via a dedicated haul road to the loading–unloading terminal (connected to a 3.7 km branch railway), from where it is exported entirely by rail.
