The thickness of tertiary is about 600 m. Since this pertains to floor strata gorge layer about 80 m coal layer at
23 m, 60 m in the overburden, the marine clay and sandstone »govški« 50 m, lithunia limestone about 50 m, in
Laško marl about 100 m and sarmatian layer about 250 m.
Important time milestones of mine Hrastnik
The beginnings of mine Hrastnik dates back to 1822, when it was mine Hrastnik granted mining rights for coal.
Mine was until 1845 owned by Joţef Luţnar. At the time, he supplied with coal sugar factory in Ljubljana and
bouyant society Sisak.In year 1845 Luţnar sold the mine, which has passed into the hands of Trieste coal mining
company. Commitment mine Hrastnik by Trieste coal mining companies accounted for Hrastnik mine as well as
the single point of Hrastnik very important historical milestone or event. Trieste is also coal mining company by
taking over the mine to enable the development of the mine Hrastnik as well as outlining the development of
other industries of Hrastnik. Some companies that were founded in Hrastnik mine at the time of acqusition by
the Trieste coal mining companies still operating succesfully.In the year 1849 was built southern railway from
Vienna via Maribor to Ljubljana. This is the beginnig of intensive industrialization in Zasavje as well as in all
other places in Slovenia, which were along the railroad.In 1852 was built in Hrastnik normal mining railroad
track, which was related to the main southern railway. Railway route was developed significantly after Hrastnik
valley along the stream Boben to the mine separation criteria. Hrastnik track is connected to the main track at the
station and passes Glasswork Factory Hrastnik and chemical products (TKI). The track at the end of the TKI is
now discontinued. In the past, through Riklov most (bridge) was connected to the mine.
Coal mining company »Trţaška premogokopna druţba« or a board memeber of Coal mining company in
»Trţaška premogokopna druţba«, George Gossleth is due to the proximity of coal in Hrastnik and better
conditions of work shifted from the chemical factory Trieste to Hrastnik, who still works succesfully.
Chemical plant has started its operation in 1860. The next major milestone in the development mine Hrastnik in
1880 when it bought the mine Trbovlje coal mining company Trbovlje (TPD), who owned the mine until all of
the second world war when the mines were nationalized by TPD.
Coal mining
Coal mine in Hrastnik lies in the eastern part of Zagorje – Laško basin and the extension of Trbovlje - Ojstrškega
basin. Trboveljsko and Ojsrško basin are contiguous and are separated artifically and practically Trbovlje
continuous coal layer passess in Ojstroi layer.
While the boundaries between coal and Hrastnik and Ojstro separate in nature, with Hrastnik valley, after which
it takes place Boben preak, which normally runs on a layer in the recent literature has together in several folds of
coal. From the level. +70 and further into the depths, up to -200 is a layer of coal regular narrow and sharply
decreasing in depth towards the south.
The cave Hrastnik traced in two layers of coal and in the eastern part of the cave floor east Hrastnik layer, which
was excavated to a level to +130. Follows a more east Angular field, which has been excavated to the level of K-
12, which is also the lowest level of excavation in the cave Hrastnik and adjacent to the western cave Dol. Both
layers of coal have reached up to the surface.Hrastnik mine was opened in the first phase sublevel opening. The
highest part of the excavation fields stretched to the level of Blato, which was the start of excavation. Then the
removal of earth field gradually progressed to a depth up to the level where it is located to the current
administration and all other mine infrastructure. At the beginning of mining, when the removal of earth a field
very near the surface, they were warmed up and fires a constant companion excavation, until they began to mine
facilities backfilling with backfill material, which was different from the headline marl, humus and soil clays
later. In the early seventies of the seventeenth century (1870 ...) had been closed due to fires, B, C, D, between
the mean field horizon and horizon XIV.Sublevel opening mine was open until 1874, when they built a house of
machine shaft and the shaft, which was the first in-depth to the horizon. Later, to II. and II. horizon. Interesting
technical equipment installed was locomobile, which is powered by steam and machinery export pump for
pumping water from the cave I horizons.In principle, the concept is a way of opening the mine pit Hrastnik
