幾個世紀(jì)以來，煤炭一直是建設(shè)現(xiàn)代經(jīng)濟的基礎(chǔ)。從早期的開采實踐到現(xiàn)代超臨界電廠和鋼鐵生產(chǎn)，煤炭的故事是技術(shù)和實踐不斷發(fā)展和完善的故事。這個故事延續(xù)到21世紀(jì)。

Coal has been fundamental to building modern economies for centuries. From early mining practices to modern ultra-supercritical power plants and steel production, the story of coal is one of continuous development and improvement in technologies and practices. This story continues in the 21st Century.
