JSW Polish mine fire, loss of 156kt of met coal

Jastrzębska Spółka Węglowa (JSW), Europe’s largest coking coal producer, has announced an adjustment to its annual production plan following a fire at the Borynia-Zofiówka mine. According to a stock exchange announcement, the incident will result in the loss of 156,000 tons of coking coal in 2025.

The fire occurred on September 12, 2025, in the Zofiówka section, where endogenous combustion forced the temporary isolation of the hazardous area. The C-2 longwall in seam 505/1 was isolated. This forced the company to suspend operations and revise its annual targets.

On September 18, the JSW management board decided to declare force majeure. The company’s partners were officially notified of the consequences of the accident for the fulfillment of contractual obligations.
