IEC60079-11 Standard Mining Cap Lamp by Green Lighting Enhancing Safety and Efficiency in Grasberg Mine

Project Background

In March 2024, Freeport-McMoRan’s Grasberg Mine in Indonesia, one of the world's largest gold and copper mines, faced significant challenges related to underground lighting. With thousands of miners working deep underground in hazardous conditions, ensuring proper illumination and safety was a critical requirement. Miners needed reliable, explosion-proof cap lamps that met international safety standards while offering long battery life, strong brightness, and robust durability.

Green Lighting was approached by Grasberg’s safety team to provide a high-performance Mining Cap Lamp compliant with IEC60079-11 standards, ensuring intrinsic safety in potentially explosive environments. Our expertise in underground mine lighting solutions made us the ideal partner for the project.


Challenges and Requirements

  1. Explosive Environment Compliance: Grasberg Mine operates in methane-prone areas, requiring intrinsically safe lighting that meets the IEC60079-11 explosion-proof standard to prevent ignition hazards.

  2. Durability in Harsh Conditions: The underground environment is wet, dusty, and high-pressure, demanding a rugged, waterproof, and impact-resistant cap lamp.

  3. Extended Work Hours: Miners work long shifts of 10-12 hours, requiring a cap lamp with a long-lasting battery that doesn’t lose brightness over time.

  4. Reliable Supplier Support: Grasberg’s safety engineers needed on-site training and continuous technical support to ensure optimal usage and maintenance.
