Donbass (Donets Basin)
돈바스
Europe's largest coalfield, spanning southeastern Ukraine and part of Russia's Rostov Oblast. A portmanteau of 'Donets Coal Basin' (Донецкий угольный бассейн), named for the Donets River, coal was discovered here in 1721 and large-scale exploitation began with the arrival of railways in the late 19th century. Its seams are thin, averaging under one metre, and deep: lignite at 600 m, anthracite down to 1,800 m, with average mining depths of 350–400 m, making working conditions among the most hazardous in the world due to methane, coal dust explosions, and rock bursts. The historic heart of Soviet heavy industry, it remains Ukraine's steel and chemical hub, though Russian military intervention and war since 2014 have devastated its economy and society.
