Association SRETNO!

The "Sretno!" Association was founded in 1998 and gathers current and former students, as well as staff of the Faculty of Mining, Geology and Petroleum Engineering, with the aim of maintaining and promoting mining tradition, the mining spirit, and fostering a strong sense of community.

The Association's most important activity is the organization of the traditional "Jump over the leather apron" event, which takes place biennially to celebrate St. Barbara's Day—the patron saint of miners, geologists, and petroleum engineers. This ceremony symbolizes the formal admission of fresh men into the honorable mining guild. The ritual dates back to history when young miners were inducted into the guild by jumping over a mine shaft, while today, due to technological developments, the jump is performed over a symbolic mining skin. Distinctive black mining uniforms with exactly 33 gold-plated buttons in honor of St. Barbara, along with a series of traditional rules, make this event unique.

The event and the overall work of the Association are the result of the dedicated and voluntary efforts of students, faculty staff, and other prominent members.

The XXXVI Jump over the leather apron will take place on December 5, 2026, in the Crystal Ballroom at The Westin Hotel, starting at 7:00 PM
