One of the preserved shaft-headframe structures of Mina Petrila, Romania’s oldest coal mine and now a listed industrial heritage ensemble.
This record documents one of the preserved shaft structures of Mina Petrila, the oldest coal mine in the Jiu Valley and in Romania. Mina Petrila operated from the first concession of 1858 until final closure in 2015. The mine developed through several major shafts, including Puțul Deak, Puțul Centru, Puțul cu Schip and Puțul 2 Est.
Key structures including Puțul Centru, Puțul cu Schip, the compressor building and the mechanical workshops were listed as historic monuments in 2015 and now form part of the post-closure heritage ensemble at Petrila. This record should be read as a shaft-specific entry within the Mina Petrila complex.
Mina Petrila occupies a site on the east bank of the Jiu de Est river in the town of Petrila, Hunedoara County, at the eastern end of the Jiu Valley coalfield. It was the first mine opened in the valley and operated for 156 years, becoming the deepest coal mine in Romania.
The formal origin of the mine dates to 30 December 1858, when the first mining concession on the territory of Petrila was registered at the Tribunal of Deva under the name Concesiunea Maximilian. The concession covered 135,349 square metres and was granted to a consortium formed by Princes Maximilian and Egon Fürstenberg, Count Otto Chotek, and Barons Luis and Moricz Haber. In its first decade coal was worked at the surface. Underground working began in 1869 with the sinking of the Puțul Deak Ferencz, a vertical shaft reaching the Galeria Deak at a depth of 36.6 metres. Initially used for ventilation, the shaft was later converted to a transport and extraction role. By 1872 the horizontal galleries extending from the drift had reached 312 linear metres. In the same period the extraction shaft was deepened by a further 123 metres to Horizon V and fitted with a steam-powered Mayer winding engine with twin pistons developing 60 horsepower at a working pressure of 5 atmospheres.
In December 1918 the mines of the Jiu Valley were transferred into Romanian state administration by decree. On 29 May 1931 the Petroșani and Lupeni mining societies merged under the name Societatea Minieră Petroșani. Under this entity a modern coal preparation plant was built at Petrila with a capacity of 270 tonnes per hour, described at the time as one of the largest in the world.
Following nationalisation in June 1948 the mine was absorbed into the Romanian-Soviet joint company SOVROMCĂRBUNE, established by decree on 20 August 1949. The mine was placed under the Trustul Cărbunelui Petroșani, one of several trusts organised under Sovromcărbune's Petroșani directorate. Production increased significantly under Communist direction; in 1950 alone miners at Petrila extracted 76,400 more tonnes than in 1949 and 190,500 more than in 1948. Around 1948 the new Puțul Centru complex was completed, equipped with one of the most modern winding installations in Europe. Between 1970 and 1975 a second extraction shaft, the Puțul 2 Est, was sunk using a pioneering method of mechanical sinking with sliding-form concrete lining; this shaft also served as an auxiliary ventilation shaft. At peak Communist-era production the mine employed approximately 5,000 people and a coal preparation plant processed hundreds of tonnes per hour. Surface coal transport shifted to standard-gauge railway in 1970.
Sovromcărbune was eventually dissolved and the mine continued under successive Romanian state entities. A modern coal preparation plant capable of processing 5,000 tonnes in sixteen hours was commissioned. In 1982 fourteen miners died and fifteen were injured in an underground accident.
On 15 November 2008 two successive underground explosions at a depth of nearly 1,000 metres killed thirteen miners and injured fifteen others. The blasts were caused by the accumulation of toxic gases in a new working face that had been opened only one week earlier. The accident drove the mine into sharp decline: from a workforce of around 2,000 in 2008 it fell to approximately 250 by the time of final closure. Three former managers were convicted in 2010 in connection with the accident.
In April 2015 the Comisia Națională a Monumentelor Istorice voted to list the mine as a historic monument. By Ministerial Order 2823/2015, the ensemble was classified as a historic monument of group A (exceptional national value), with individual components including the compressor building, mechanical workshops, Puțul Centru and its hall, Puțul cu Schip, Puțul Deak, the old coal preparation plant, and the former power station chimney receiving separate classifications.
The last tonne of coal was brought to the surface on 30 October 2015, in a brief ceremony attended by the remaining miners. The mine's formal closure was enacted on 30 November 2015. Most of the surface buildings were subsequently demolished. The listed structures passed to the Societatea Națională de Închideri Mine – Valea Jiului (SNIMVJ). A museum of mine rescue was opened within the complex in 2018.
In 2022 Consiliul Județean Hunedoara purchased the site — the 163,855 square metres of land and listed buildings — from SNIMVJ for 1.5 million lei. The ensemble has been partially opened to visitors on two marked itineraries covering the shaft towers, compressor building, Galeria Deak, and other structures. Cultural events including the international opera festival Opera Nights were held within the complex in 2023 and 2024. The site's buildings remain in a fragile condition, having suffered extensive theft of metalwork and structural deterioration since closure.
