2020-6-4German hard coal production ended in 2018, following the termination of subsidies. This paper looks at 60 years of continuous decline of an industry that employed more than 600,000 people, through a case study comparing Germanys two largest hard coal mining areas Ruhr area and Saarland. Although predominantly economic drivers underlay the transitions, both provide valuable lessons for.

Since the beginning of the 1990s, the Polish mining industry has been going through a process of transformation. Hard coal production decreased from 177.4 million tonnes in 1989 to 63.4 million tonnes in 2018. Over the same period, employment in the Polish hard coal mining sector decreased from 407 000 to 82 843 employees at the end of 2018.

With mining technology and mechanization degree being improving, fully mechanized caving mining technology FCM has become a main method for thick coal seam extraction in China. However, roof-coal caving characteristics in turn restrict its recovery efficiency, especially for the coal seam with complicated structure CCS, that is, the coal seam comprises hard or soft coal and gangue.

Continuous decline. Because of relatively high production costs hard-coal mining in Germany seemed not to be capable of competing in the world market any more. Since the end of mining has been definitely decided at the beginning of the 21st century, RAG is turning from an active hard-coal producer to a post-mining.

2020-6-2Coal mining is the process of extracting coal from the ground. Coal is valued for its energy content and since the 1880s, has been widely used to generate electricity. Steel and cement industries use coal as a fuel for extraction of iron from iron ore and for cement production. In the United Kingdom and South Africa, a coal mine and its structures are a colliery, a coal mine is a pit, and.
