Neuroder Revier
Historic hard coal mining district in Lower Silesia
From Wikipedia, the free encyclopedia
The Neuroder Revier was a historic hard coal mining district centred on Neurode (today Nowa Ruda, Poland) in Lower Silesia. It formed the south-eastern part of the former Lower Silesian Coal Basin and belonged to the wider Waldenburg–Neurode mining region.[1] Coal mining in the district is documented from 1434, making the Nowa Ruda area one of the oldest documented hard coal mining centres in present-day Poland.[2][3] Mining continued, with interruptions, mergers and administrative changes, until 2000, when mining operations in the last active field, Słupiec, came to an end.[4]
Geography and geology
The Neuroder Revier lay in the central Sudetes, between the Owl Mountains and the Bohemian frontier. Geologically it belonged to the Lower Silesian Coal Basin, whose principal coal-bearing areas included Wałbrzych and Nowa Ruda.[5] The mining district covered an area of about 99.8 km² and included workings in and around present-day Nowa Ruda, Słupiec, Ludwikowice Kłodzkie, Przygórze and nearby settlements.[4] The basin's complicated tectonics and the frequent occurrence of gas and rock outbursts made mining difficult and expensive, particularly in deeper seams.[5]
History
Early history
The earliest known documentary reference to coal mining in the Neurode area dates from 1434.[2][3] For centuries, however, local mining remained small in scale. A major institutional change followed the incorporation of the County of Glatz into Prussia, when the revised Silesian mining ordinance of 1769 placed the district under a more formal mining administration.[1] At that time only four mines were active in the district: Frischauf, Johann Baptista, Joseph and Wenzeslaus.[1]
Nineteenth century
During the late eighteenth and nineteenth centuries the district expanded gradually. According to Zygfryd Piątek, sixteen mines were operating in 1799, employing 158 miners and producing 16,817 tonnes of coal.[1] Over the nineteenth century ownership became more concentrated and many smaller pits were merged or closed.[1] Railway connections to Kłodzko and Wałbrzych, opened in 1879–1880, improved transport links and stimulated further growth in the coal industry.[2]
By the early twentieth century production was concentrated in four major mines: Wenzeslaus, Ruben Mine, Rudolph Mine and Johann Baptista.[1] In 1912, Wenzeslaus was the district's largest producer, with 564,966 tonnes, followed by Ruben with 225,976 tonnes, Johann Baptista with 160,135 tonnes, and Rudolph with 57,576 tonnes.[1] Although mining grew steadily, it developed alongside textile manufacturing and only became the dominant branch of the local economy comparatively late.[1][2]
Industrial hazards
The Neuroder Revier was one of the most dangerous mining districts in Lower Silesia because of its geology and the prevalence of carbon dioxide hazards.[6] The largest documented disasters in the district were the outburst at the Wenceslaus mine in 1930, in which 151 miners died, and the 1941 catastrophe at the Ruben mine, in which 187 miners were killed.[6] These accidents rank among the deadliest mining disasters in the history of Lower Silesian coal mining.[6]
After 1945
After the Second World War, the area became part of Poland and Neurode was renamed Nowa Ruda.[2] The mining industry was reorganized under Polish administration. According to the municipal history of Nowa Ruda, the post-war Kopalnia Węgla Kamiennego "Nowa Ruda" incorporated the Piast field (formerly Ruben) and the Słupiec field (formerly Johann Baptista).[2] The mine was gradually wound down in the post-communist period; extraction in the Piast field ended in 1994, while the Słupiec field continued until 2000.[2][4]
Legacy
The closure of the mines had major social and economic consequences for Nowa Ruda and the surrounding region. Former mining infrastructure in Nowa Ruda has partly been preserved as industrial heritage, including the former mine complex now used as a museum and underground tourist route.[3] Recent research has also examined the energy potential of mine water in the flooded workings of the former district.[5]
