Question: What did the Thuringian miners do to help the country that the author of With the Century is a citizen of?

he was an author of numerous memoirs on the geology of russia, especially on coal and other mineral deposits of the country; and he wrote also some explanations to accompany separate sheets of the geological map of russia. <SEP> the western federation of miners (wfm) was a radical labor union that gained a reputation for militancy in the mines of the western united states and british columbia. its efforts to organize both hard rock miners and smelter workers brought it into sharp conflicts – and often pitched battles – with both employers and governmental authorities. one of the most dramatic of these struggles occurred in the cripple creek district in 1903–04, and has been called the colorado labor wars. the wfm also played a key role in the founding of the industrial workers of the world in 1905, but left that organization several years later. <SEP> The memoirs, written in 1992 and published in eight volumes, retell Kim's life story through his childhood to the time of Korean resistance. Reminiscences: With the Century () is the autobiography of Kim Il-sung, founder and president of North Korea. Initially, a total of 30 volumes were planned but Kim Il-sung died in 1994 after just six volumes; the seventh and eight volumes were published posthumously. The work reveals early influences of religious and literary ideas on Kim's thinking. An important part of North Korean literature, "With the Century" is held as a valuable if somewhat unreliable insight into the nation's modern history under late colonial Korea. The book is considered one of a few North Korean primary sources widely available in the West and as notable research material for North Korean studies. <SEP> Mining was important in Thuringia since the later Middle Ages, especially within the mining towns of the Thuringian Forest such as Schmalkalden, Suhl and Ilmenau. Following the industrial revolution, the old iron, copper and silver mines declined because the competition from imported metal was too strong. On the other hand, the late 19th century brought new types of mines to Thuringia: the lignite surface mining around Meuselwitz near Altenburg in the east of the Land started in the 1870s, and two potash mining districts were established around 1900. These are the Südharzrevier in the north of the state, between Bischofferode in the west and Roßleben in the east with Sondershausen at its centre, and the Werrarevier on the Hessian border around Vacha and Bad Salzungen in the west. Together, they accounted for a significant part of the world's potash production in the mid-20th century. After the reunification, the Südharzrevier was abandoned, whereas K+S took over the mines in the Werrarevier. The centre was Ronneburg near Gera in eastern Thuringia and the operating company Wismut was under direct Soviet control. Between 1950 and 1990, uranium mining was also important to cover the Soviet Union's need for this metal. <SEP> On 9 September 1948, the DPRK was proclaimed, also led by Kim Il-sung. At the end of World War II, Soviet Union occupied the northern half of Korea and in 1946 established the Provisional People's Committee for North Korea chaired by Kim Il-sung.
