Background
The JSW coal mines are group of underground operations, owned by JSW Group in Silesian, Poland.[15]
The mines operating include Knurów-Szczygłowice, Borynia-Zofiówka-Jastrzębie, Budryk, and Pniówek.[16] The mines produce 14.8 mt of coal and 3.2 mt of coke. The mines are operated by JSW and produce coking coal.[16] The Pniówek mine is the gassiest mine in Poland and is considered a category IV methane hazard. [17] The mines are regularly changing names and being consolidated, the Borynia and Zofiókwa mines were merged together in 2011 to form the Borynia-Zofiówka mine. [18]
In 2018 an earthquake led to a collapse in the Borynia-Zofiówka mine. There were 240 miners working in the mine when it collapsed, 5 miners were killed and two were injured while drilling a new tunnel at a depth of 900 metres. The high concentrations of methane in the mine, which reached a concentration of 58% at times, hindered the rescue operation. [19] [20]
In 2020 JSW were forced to suspend mining operations in a number of their sites after coal mines in the Silesian region suffered widespread COVID-19 outbreaks. At one point almost 60% of Poland's daily infections came from mines in the Silesian area, making JSW mines, amongst others, a regional hotspot for the virus. [21] [22]

Methane Venting from Drainage System and Fatal Explosion
On 22 January 2025, a fatal methane explosion occurred at the Szczygłowice mine; the event was detected by the Tanager-1 satellite.[27] A
February 2026 satellite-based analysis by Ember also found that the mine's drainage system vented methane on two occasions in 2025, despite an EU-wide ban on routine venting from coal mine drainage systems that took effect in January 2025. Plumes were detected on 22 January 2025 (1,054 kg/h) and 21 February 2025 (1,097 kg/h); both were attributed with high confidence.[27] The same report by Ember identified repeated methane venting from the drainage system at the Borynia unit of the Borynia-Zofiówka mine in 2025; plumes were detected on 30 July, 20 August, and 22 October 2025, with estimated emission rates of 1,125, 700, and 880 kg/h respectively.[27]
Coal Mine Boundaries and Methane Sources
Global Energy Monitor researchers have identified coal mine boundary/boundaries and potential sources of coal mine methane (CMM) for this mine. These research results can be used to drive CMM attribution and mitigation efforts, particularly when combined with remotely sensed methane plume locations and mine ownership data. Explore the results with the embedded map at the top of this page by clicking on the mine boundary polygon or the CMM placemarkers to reveal more details. A detailed description of this research can be found in Coal Mine Boundaries and Methane Sources. This data is also available as a downloadable companion dataset to the Global Coal Mine Tracker and the Global Methane Emitters Tracker.

Associated Coal Mine Methane Mitigation Projects
Some coal mines have installed infrastructure which can use and/or destroy some methane emissions associated with mining. In 2024, the Global Methane Initiative reported that this mine had a mitigation project associated with it. This methodology page describes how GEM classified these projects and linked them with coal mines in the Global Coal Mine Tracker.
Table MM1: Methane mitigation projects
| Mitigation Project Name | Project Type | GMI Reported Status | GMI Reported Start Year |
|---|---|---|---|
| Knurów-Szczygowice CHP Project - Poland | utilization | Operational | 2005 |
| Szczyglowice Mine Flaring - Poland | Flaring | Stalled | 2011 |
Methane Plumes Detected Nearby
Global Energy Monitor researchers analyze satellite-detected methane plumes in order to determine whether they have been observed at or near the site of GEM energy assets. The satellite data provider creates imagery of individual methane plumes and estimates their emission rates at the time of observation. GEM has reviewed many of these plume detections against Google Earth imagery and GEM’s own energy infrastructure tracker data. The following table lists methane plumes which are associated with the energy asset or facility based on distance and manual review. (A full description of the analysis process is available in the Global Methane Emitters Tracker methodology wiki page.)
