Case Study: Overseas On-site Technical Support

“Enable large-scale electronic detonator blasting in open-pit coal mine”

Project Overview

As the world's largest hydropower project, the Medog Hydropower Station redefines engineering excellence. With an installed capacity of 60-81 GW (3x the Three Gorges Dam) and annual output of 300-400 TWh, it will supply 4.5% of China's total electricity demand—equivalent to powering 300 million households. This $120 billion megaproject harnesses the Yarlung Tsangpo River's 2,230-meter natural drop through 4-6 tunnels (20-35 km each), overcoming Himalayan seismic zones and 70°C tunnel temperatures.

Technical Challenges

• Geological Mastery: Designed to withstand M8.5 earthquakes, the project employs flexible concrete tunnels and 3D seismic isolation systems, navigating 5 major fault lines.
• Precision Blasting Technology: Digital electronic detonators enable microsecond-level detonation control, reducing vibration by 80% during tunnel excavation—critical for protecting the fragile ecosystem of the Yarlung Tsangpo Grand Canyon.
• Sustainable Innovation: Preserving 30% of natural river channels and maintaining 800 m³/s ecological flow ensures minimal impact on biodiversity.

Solutions

As the exclusive provider of electronic detonator control modules, Chipdance's technology ensures pinpoint accuracy in blasting operations. Its microchip-based timing systems (±1ms precision) and real-time network monitoring have been instrumental in excavating the project's 2400-meter-deep tunnels, where traditional methods would risk catastrophic rockbursts.
