山东莱芜是一个煤炭产区,莱芜煤田属于石炭二叠系,含煤20余层,开采条件较好,煤炭开发历史较悠久。资料表明,莱芜地区至迟在南宋后期就出现了采煤业。据元代延祐二年(1315年)所镌的一块石碑记载,当时莱芜冶铁业十分发达,其所需大量的冶铁燃料——煤炭,就是取自于当地。到了明代,莱芜的煤炭大量炼烧成焦炭。 Shandong Laiwu is a coal producing area. The Laiwu coalfield belongs to the Permo-Carboniferous system with more than 20 coal-bearing layers. It has good mining conditions and has a long history of coal exploitation. The data shows that the coal mining industry emerged in the Laiwu region late in the Southern Song Dynasty. According to a stone monument recorded in the Yanyou two years (1315) in the Yuan Dynasty, the iron and steel industry in Laiwu was very developed. The large amount of iron-smelting fuel it needed, coal, was taken from the local area. In the Ming Dynasty, the coal of Laiwu was burned into coke.
