2009 Handlová mine blast

The 2009 Handlová mine blast occurred on 10 August, 2009 roughly 330 metres (1,080 ft) underground in Trencin Region, Slovakia at Hornonitrianske Bane Prievidza, a.s.s (HNB) coal mine located in the town of Handlová. 20 people were killed, nine others suffered minor injuries and were taken to hospital for treatment. Some historians have called the disaster the largest mining tragedy in Slovakia’s history. The deadly explosion, probably caused by flammable gases, occurred after mine rescuers had earlier been deployed to extinguish a fire in the Eastern shaft of the mine.^[2]
