Preserved national cultural monument and open-air mining museum in Ostrava-Michálkovice, with intact 1912–1915 pithead complex and original electric winding equipment.
Důl Michal is a former deep black-coal mine in the Ostrava-Michálkovice district of Ostrava, operating from 1843 until the cessation of winding in 1993 and final shaft backfilling in 1995. The mine takes its name from Michael Layer, an imperial court councillor after whom the shaft was renamed in 1850. Purchased in 1856 by the Severní dráha Ferdinandova (Ferdinand Northern Railway Company), it remained in that company's ownership until nationalisation in 1945.
The present character of the site derives almost entirely from a comprehensive reconstruction carried out between 1913 and 1915 to designs by architect František Fiala, a pupil of the Viennese modernist Otto Wagner, during which steam power was replaced throughout by electrical drive. The pithead buildings, machine room, compressor room, and welfare facilities have survived without substantial subsequent alteration and are preserved in the condition of the last working day. The site was declared a national cultural monument in 1995 and has been open to the public since April 2000, administered by the Národní památkový ústav.
It is also an anchor point on the European Route of Industrial Heritage.
The earliest history of the site begins in 1842, when the Austrian imperial mining administration (the montánní erár) established a licensed prospecting area at Michálkovice and in 1843 began sinking two shafts. The first of these, known as jáma Ferdinand, was later abandoned and had ceased to exist by the 1880s. The second shaft was named Michal after Michael Layer, an imperial court councillor who had been a prominent figure in the development of mining in the region; the name was formalised in 1850. In 1856, as state-directed mining operations were recording substantial losses, the mine was purchased by the Severní dráha Ferdinandova, the company that owned and operated the railway running from Vienna through Ostrava to the Polish salt mines. The company retained ownership of Důl Michal until nationalisation in 1945, giving the mine an unusually long and stable period under a single private proprietor.
The connection to the báňská dráha (mining railway) in 1862, which linked the mine to Přívozu and allowed coal to be despatched by rail, marked the first major operational milestone. The shaft serving winding reached a depth of 161.2 metres in 1863, with timber lining and cross-section dimensions of 2 by 3 metres; a steam-powered pump rated at 16 HP handled drainage, and a steam winding engine of 30 HP with a horizontal cylinder carried out hoisting. Coal was worked in the Jaklovecké strata. A first major structural intervention took place around 1870, when the upper section of the shaft tower collapsed and the shaft building, machine room, and boiler house had to be rebuilt. By 1882 production from jáma Ferdinand had been transferred to jáma Michal, which was serving as the combined winding shaft; by that date the shaft reached 243.5 metres. By 1898 the full cross-section of the Michal shaft was in use for intake ventilation, by which time the Guibal fan and the suction pump were no longer operational, and the shaft had been deepened to 397.8 metres.
In 1907 mechanised drilling during roadway development was introduced, together with coal-cutting machines. The decisive transformation of the site came between 1913 and 1915, when the mine was comprehensively rebuilt to plans by architect František Fiala, a pupil of the Vienna school of Otto Wagner, with the intention of concentrating production from several smaller surrounding collieries at a single modern pit. In the same period, the haulage of coal from the neighbouring doly Petr a Pavel (Michálkovice) was transferred to Důl Michal in 1913, and from the doly Jan and Josef (Slezská Ostrava) in 1916, with their mining fields absorbed into the Michal concession area, which grew to 411 hectares. As part of the reconstruction, steam power was replaced throughout by electrical drive: the new machine room was fitted with two electric winding engines each rated at 2,480 HP, with electrical equipment by Siemens-Schuckert of Vienna and mechanical parts manufactured at Vítkovické železárny. A compressor room was constructed alongside. By 1916 the mine was raising 383,400 tonnes of coal annually. The winding shaft ultimately reached a depth of 671 metres, with coal being worked in 17 seams of 50 to 200 centimetres thickness at depths of up to 960 metres.
Following nationalisation in 1945, the mine was absorbed into the state enterprise Ostravsko-karvinské kamenouhelné doly, n.p. In July 1946 it was renamed Petr Cingr, after a Social-Democratic mining-region leader who had sat in the Austrian Reichstag; the mine operated under this name throughout the socialist period. Further reconstructions during the 1920s, 1940s, and at the turn of the 1950s and 1960s were confined to the coal preparation plant, coal loading facilities, and construction of a new electrical substation, and left the 1912–1915 pithead complex essentially undisturbed. In 1990, following the political changes of 1989, the mine reverted to its original name Michal.
Closure came on 30 May 1993, when coal winding ceased at what was formally styled Důl Petr Cingr; the last cage ascent on the auxiliary winding engine took place on 2 June 1994. Backfilling of the winding shaft was completed in 1995. Already during the closure period, in 1994, the Ministry of Culture of the Czech Republic took over the entire site and established the Průmyslové muzeum v Ostravě (Industrial Museum in Ostrava) there. That institution was wound up in 2000, and the site was transferred to the Národní památkový ústav (National Heritage Institute). In 1995 the complex had been declared a national cultural monument; its official registered designation is Uhelný důl hlubinný Michal/Petr Cingr, identifier 120138.
The preserved complex encompasses the shaft building, the machine room with its two original electric winding engines and original compressor room, the boiler house, the chain-type changing rooms, washrooms, lamp room, guildhall, dispatch centre, first-aid room, and administrative offices — all maintained in the condition of the last working day, without restoration or cosmetic improvement. An original steam engine dating from 1903 is also among the exhibits. Since April 2000 the site has been open to the public as a museum under the administration of the Národní památkový ústav, territorial administration branch in Kroměříž. Důl Michal is additionally listed as an anchor point on the European Route of Industrial Heritage (ERIH) and appears on the Czech Republic's indicative list for potential UNESCO inscription.
