Budryk Coal Mine
The construction of the youngest Polish mines began in 1979, but it did not obtain a ministerial mining concession until 1994. In 2007, it became the arena of workers' strikes announced after the news of plans to incorporate Budryk Coal Mine into Jastrzębska Spółka Węglowa. Job concerns and wage demands resulted in a 46-day strike. Thirty miners, out of 130 protesters, went on hunger strike, staying underground. The strike ended in January 2008 with an agreement with the management board of JSW. Shaft VI, called Chudów, is Poland's deepest coal mining level; after deepening it in 2015, a level of 1290 m was reached.
