A lot of people wasted their potential, but not Jan Váňa. He was sent to look for coal by the capitalist Václav Novotný and thus had a certain amount of capital at his disposal, which gave him an advantage over the others. In the pub he met František Jirátko, a gardener and mason from Bustěhrad. When Jirátko was already about twenty meters deep, Váňa told Jirátko that he no longer had a chance to find coal, and bought the land from him in 1846. A few meters deeper, he found the first coal seam, and the first Kateřina Josefa mine was soon opened on the spot.
