The ETT Coking Coal Mine Project is one of the world's largest undeveloped coking coal mine projects, with proven reserves reaching 8.1 billion tons, accounting for over 30% of Mongolia's coal production capacity. Its projected coal exports to China will hit 40 million tons in 2025, making it of great significance for safeguarding the security of China's coal resources. DFMC injects core technological strength into the ETT Project: it has built an intelligent dispatching system for open-pit mine vehicles based on an AI large model, incorporating more than 200 units of mining equipment into full-domain intelligent management and control. Relying on real-time working condition perception, dynamic path planning and multi-equipment collaboration algorithms, the system constructs a closed loop of "safety prediction – efficiency optimization – intelligent decision-making". It accurately matches the needs of mining and stripping operations, greatly reduces the risks of manual operation, significantly increases the total annual stripping and mining volume, and strongly supports the mine's smart and unmanned transformation.
