Closed brown coal mine shaft at Handlová, site of Slovakia's worst modern mining disaster on 10 August 2009.
Východná šachta (East shaft) was a section of Baňa Handlová, the brown coal mine at the town of Handlová in the Trenčín Region of central Slovakia, operated by Hornonitrianske bane Prievidza a.s. It extracted the highest-quality brown coal deposit in Slovakia, at a working depth of approximately 330 metres. The mine shaft is associated with elevated methane production due to the quality of the coal.
Mining was suspended in 1990 for economic reasons, resumed following a government review in 1993, and reached full production again in 2006. Mining in this section ended on 17 June 2009. On 10 August 2009 a coal-gas explosion killed 20 people — eleven mine rescue workers and nine miners — at approximately 330 metres depth, making it the worst mining disaster in modern Slovak history.
The day was subsequently designated an annual national Day of Memory for Mining Accident Victims in Slovakia.
Východná šachta formed part of the Baňa Handlová underground coal mine, operated in the twentieth century and into the twenty-first century by Hornonitrianske bane Prievidza a.s. (HBP), the main Slovak lignite producer. Handlová had been a coal-mining town for over a century; by 2009 the local cemetery held a marble monument recording the names of 445 miners who had died in accidents at the Handlová, Cígeľ and Nováky mines since 1915.
The Východná šachta section worked the highest-quality brown coal deposit in Slovakia. The elevated quality of the coal was associated with a correspondingly high production of methane and a risk of spontaneous combustion, placing the shaft in the most hazardous category under Slovak mining regulations. The mine was classified as gassy and subject to risks of coal and gas outburst, as well as water inrush. Former workers describe it as one of the most dangerous workplaces in the country, comparable in hazard classification to coal mines in Karviná and Ostrava.
In 1990 the state suspended extraction in the Východná šachta fields for economic reasons. After a reassessment of the decision, work to reopen the mine began in 1993. Active extraction recommenced in 2003 after lengthy preparatory works, and full production was restored in 2006. Mining in the Východná šachta section ended on 17 June 2009.
On the morning of 10 August 2009 a fire broke out in one of the older underground workings of Východná šachta at approximately 330 metres below surface. A dispatcher sent nine miners to the scene at approximately 07:00. Unable to extinguish the fire, they called for eleven mine rescue workers from the Hlavná banská záchranná stanica (Main Mine Rescue Station) in Prievidza, who joined the miners underground by approximately 08:30. At approximately 09:30 the telephone connection with the rescue unit commander was broken and gas monitoring sensors went offline. A massive explosion of mine gases had occurred. The pressure wave injured a further nine miners who were between 150 and 200 metres from the epicentre. All twenty underground workers — eleven rescue workers and nine miners — died. The bodies of the last fourteen were brought to the surface on 13 August 2009. A state funeral was held on Handlová's main square on 20 August 2009, and on 12 August a twelve-hour national period of mourning was declared.
The criminal investigation was complex. Three employees of Hornonitrianske bane Prievidza were charged with general endangerment. In May 2015 the Prievidza District Court convicted all three and sentenced them to between five and eight years' imprisonment with a ban on holding senior management positions in mines. The verdict was subsequently overturned on appeal and returned for retrial; the Prievidza District Court reconfirmed its original conviction in a later judgment, which was again the subject of appeal. The case remained unresolved through proceedings into the 2020s.
The National Council of the Slovak Republic designated 10 August as a national Day of Memory for Mining Accident Victims (Deň obetí banských nešťastí) in October 2010. A bronze memorial depicting miners of past and present was erected in Handlová, and from 2011 white roses were laid there annually on the anniversary as part of the Deň bielych ruží (Day of White Roses) commemoration.
Note: The supplied town field "Banská Hodruša area" and the general designation of this site in the database appear to be an error. The Východná šachta is part of Baňa Handlová at the town of Handlová, Trenčín Region, which is distinct from Banská Hodruša (Hodruša-Hámre), a historic precious-metal mining settlement in the Banská Bystrica Region approximately 80 km to the east.
