A coal mine which started in 1899 as Schoeller mine (after Gustav Schoeller, Austrian mining entrepreneur). From 1946, it was named Zdeněk Nejedlý Mine (historian, musicologist, and minister of culture in communist government), from 1951 Nejedlý I Mine. After 1990 again renamed: Kladno Mine in Libušín. Terminated 2002 after 2001 methane explosion with four casualties.

The mine was active for exactly 100 years and in total 45,768,396 tons of coal was mined. The depth of mine pit 533 m, shaft bottom 518 m. The famous burning dumps of Schoeller mine are now fully recultivated.

Note on the mineral list:
The famous minerals from the burning coal dumps in the Kladno area occurred mainly here, but also in other mines with (temporarily) burning dumps. Since the literature only rarely gives the specific mine, these minerals are listed under Kladno.

SALAMMONIAC (SALMIAC) (NH4 Cl): fine crystals on matrix and nice thumbnail specimens from this classic locality. Salammoniac forms on volcanic rocks near fume releasing vents. There is no liquid phase as the mineral crystallizes from these fumes in a process called sublimation. The crystallization occurs as the gases are escaping and crystals tend to be short-lived. Salammoniac is very soluble in water and crystals will be removed during the first rain of their existence, so to speak, if they are not removed by collectors first.

GODOVIKOVITE: rare mineral looks like porous ochre masses on matrix with nice specimens from this classic locality. Godovikovite is a rare sulfate mineral with the chemical formula: (NH4)Al(SO4)2. Aluminium can partially be substituted by iron. Hydration of godovikovite gives the ammonium alum, tschermigite. The mineral forms cryptocrystalline, often porous, masses, usually of white colour. Single crystals are very small hexagonal blades. A typical environment for godovikovite is burning coal sites (mainly dumps). There the mineral acts, together with millosevichite, as one of the main components of so-called sulfate crust.

An unnamed aluminium chloride Al2Cl(OH)5.2H2O associated with lesukite.
