阿巴拉契亚煤田阿巴拉契亚煤田AppalachianCoalBasin世界产量最大的煤田。分布在美国东部的9个州(西弗吉尼亚、宾夕法尼亚、肯塔基、俄亥俄、亚拉巴马、弗吉尼亚、田纳西、马里兰、佐治亚)。含煤面积18万平方千米。含煤地层属石炭纪。900米深度内的地质总储量为3107亿吨，1991年1月1日探明储量937.6亿吨，其中可采储量499亿吨。阿巴拉契亚煤田以盛产优质炼焦煤闻名于世，煤田北部的匹兹堡煤层，面积5440平方千米，探明储量120亿吨，挥发分37％，灰分7％，硫分2.2％，发热量32.35兆焦／千克。在宾夕法尼亚东部，有美国唯一的无烟煤资源。亚拉巴马州有少量褐煤。该煤田开采条件十分优越。99％是近水平煤层，煤层平均厚1.7米，矿井平均开采深度仅70米，许多地方可露天开采。矿井广泛采用短壁采煤法和大型无轨采运设备。阿巴拉契亚地区矿产资源丰富，雨量充沛，水陆交通便利。其近代煤炭工业在19世纪60年代南北战争以后兴起，20世纪初已成为世界最大煤炭基地。后来在采煤的基础上，逐步形成拥有煤炭、电力、钢铁、机械等行业的巨大工业中心。1991年生产商品煤4.16亿吨(原煤约4.78亿吨)。阿巴拉契亚煤田采掘现场
