The Johann-Baptista Mine was a bituminous coal mine in Słupiec, Nowa Ruda in Lower Silesia. It belonged to the Waldenburg South mining district.[1]
18th century
Coal was mined at the mine at least since 1742.[1] In 1769, there were four mines in the Duchy of Silesia and the County of Kladsko: Frischauf in Eckersdorf, Johann Baptista in Schlegel, Joseph in Neurode-Buchau, and Wenzeslaus in Hausdorf. These four mines together employed 35 people and produced about 1,400 t of coal per year.[2]
19th century
In 1858, the mine produced over 10,000 t of coal per year.[3]
20th century
In 1912, the mine had 6 shafts, a mining depth of 233 m, two steam engines with 70 hp, and one electric motor with 5 hp.[3]
Coal production in 1912 was 160,135 t, with 977 employees and extraction costs of 7.27 RM per tonne. The annual net wage of a mine worker was 869 RM.[4]
In 1929, 163,584 t of coal were mined, and there were 702 employees. In 1937, 194,880 t of coal were mined and there were 639 employees. In addition, there were 3.5 km of underground locomotive tracks.[5]
After 1945
After the Second World War, the mine continued to operate under Polish administration. In 1971, the Słupiec site was merged with the Nowa Ruda mine into the joint Nowa Ruda Coal Mine.[6] In the post-war period, coal mining was an important branch of the economy and contributed significantly to the development of the region.[7]
Coal extraction in Słupiec, and thus in the area of the former Johann-Baptista Mine, ended on 8 February 2000.[8]
With the end of coal mining in Słupiec, coal mining in the region came to an end. Today, the Dawna Kopalnia mining museum in Nowa Ruda commemorates this history.[9]
