Protected 45-metre steel headframe of jáma Pokrok 1/1, the last visible remnant of the former Důl Julius Fučík at Petřvald, standing within an industrial estate.
The site recorded under the canonical name Bývalý důl Pokrok (Fučík I) in Petřvald is the former primary shaft of the Důl Pokrok colliery, founded in 1912 by the Báňská a hutní společnost (Austrian Mining and Metallurgical Company) as Důl Habsburk. Coal seam working in the Petřvald partial basin began as early as 1835, but the Pokrok shaft — with its main winding jáma Pokrok 1/1 sunk to a depth of 606 metres and ventilation shaft to 413 metres — was the most modern operation in the basin. Renamed Pokrok in 1920 and merged with Důl Hedvika as the large-scale Důl Julius Fučík in 1953, the colliery was the last in the Petřvald basin to mine coal, with production ending on 28 February 1998.
The primary shaft jáma Pokrok 1/1 is now the sole surviving structure on the former mine site. The 45-metre steel braced headframe of this shaft was declared a cultural monument of the Czech Republic on 3 April 1997, before the end of mining, and remains standing surrounded by new industrial halls.
The Petřvald partial basin of the Ostrava-Karviná coalfield saw its earliest coal mining from around 1835, when prospecting shafts and shallow workings were established in areas where seams lay close to the surface. The first documented shallow mines in the basin were Důl Žofie (1835) and Důl Evžen (1836), followed over subsequent decades by Důl Václav (1854), Důl Pokrok and Důl Hedvika (1872), and Důl Ludvík (1898). The founding of what later became the Pokrok shaft, however, belongs to the early twentieth century.
On 29 May 1912 the Báňská a hutní společnost (Austrian Mining and Metallurgical Company) formally established a new deep mine at Petřvald under the name Důl Habsburk, after the Austrian imperial dynasty. Sinking of the ventilation and winding shafts took place in 1911–1912, and the associated surface buildings were constructed at the same time. Coal production began in 1913. Early output figures show the rapid growth of the operation: 50,070 tonnes in 1914, 149,400 in 1915, 210,700 in 1916, reaching 412,400 tonnes in 1926 and 397,000 tonnes in 1927. The main winding shaft jáma Pokrok 1/1 was sunk to a depth of 606 metres; the ventilation shaft reached 413 metres. Working was carried out in four seams of 70 to 220 centimetres thickness and two further seams being prepared for exploitation in 1928. In 1928 the mine was equipped with six large mobile coal-cutting machines (Knapp-Eickel system) for roadway development, 115 pillar cutters, 120 drilling hammers, 135 impact hammers, 117 shakers with chutes, 96 winches, six petrol locomotives (Deutz system), and one diesel locomotive.
In 1920 the name of the former ruling dynasty was removed from the colliery designation and the mine was renamed Pokrok (Progress), reflecting the progressive mining methods that the company declared to be in use. The mine continued to expand production under its new name through the interwar period and the Second World War. Following nationalisation in 1945 the mine was incorporated into the state mining structure. In 1951 Důl Pokrok was renamed Důl Julius Fučík after the communist journalist and resistance martyr. From the beginning of February 1953 the mine was merged with the adjacent Důl Hedvika to form the large-scale Důl Julius Fučík, with the former Pokrok installation becoming závod 1 (shaft operation no. 1) and the former Hedvika becoming závod 2. In 1961 Důl Ludvík was absorbed into Důl Julius Fučík, and in 1970 Důl Čs. Pionýr (itself a consolidation of doly Václav, Evžen, and Žofie) was also incorporated, creating a colliery with six shaft operations and a surface coal-preparation complex. At this scale Důl Julius Fučík was a major operation: peak production across the six shaft operations in 1963 reached 4,181,700 tonnes, achieved from seams in shallow to steeply inclined configurations. In the early 1960s the annual output of the Pokrok shaft operation alone fluctuated around 820,000 tonnes.
In 1971 and 1972 workers from Důl Fučík participated in the introduction of mechanised coal extraction in Algeria. From the late 1980s until 1998, 37 workers from the mine successively assisted with the introduction of powered roof supports and shearer loaders at collieries in the Asturias and León regions of northwestern Spain. Annual output at the Pokrok shaft reached its recorded peak of 943,870 tonnes in 1976. From the early 1980s production declined progressively. After 1990, under the general restructuring of the Ostrava-Karviná coalfield, it became a matter of time before the shaft operation would close.
On 3 April 1997, before mining had ceased, Ministerstvo kultury České republiky (Ministry of Culture of the Czech Republic) declared the headframe of jáma Pokrok 1/1 a cultural monument of the Czech Republic. Coal winding at závod Fučík 1 (Pokrok) ended on 28 February 1998, and the last coal tub from jáma Pokrok 1/1 was ceremonially raised on 2 March 1998. Working depths in the Petřvald basin had reached up to 820 metres below surface. Over 163 years of mining in the Petřvald partial basin, 82 shafts and exploratory shafts were sunk and approximately 207 million tonnes of black coal were extracted; at the Pokrok shaft alone, approximately 46 million tonnes were extracted during the mine's existence.
Following closure, surface liquidation began progressively. In 2006 the monument protection was withdrawn from the strojovna and kompresorvna (machine room and compressor room), the old boiler house, the locksmith's workshop, and the coal-preparation plant, and in January 2009 demolition of those buildings was carried out. The electric winding engine Brown-Boveri and a steam turbocompressor PTK 36 were transferred to the machine room of NKP Důl Hlubina in Ostrava before demolition. The sole surviving protected structure is the steel braced headframe of jáma Pokrok 1/1, 45 metres high, which remains standing on the former mine site, now surrounded by new industrial buildings. No public access to the headframe has been established.
