补充资料：石煤
| 石煤 stone coal 形成于早元古代和早古生代的一种沉积的可燃有机岩。呈黑色或黑灰色。大多具有高灰、高硫、低发热量和硬度大的特点。石煤是一种高变质的腐泥煤或藻煤。其成分除含有机碳外，还有氧化硅、氧化钙和少量的氧化铁、氧化铝和氧化镁等。石煤有各种不同的分类。按灰分和发热量，可分为一般石煤和优质石煤：一般石煤的灰分为40％～90％，发热量在16.7千焦／克以下；优质石煤的灰分为20％～40％，发热量为16.7～27.1千焦／克。按结构、构造，可分为块状石煤、粒状石煤、鳞片状石煤和粉状石煤。按石煤中矿物杂质的主次，分为硅质石煤、钙质石煤等。石煤在中国分布广泛以南秦岭区储量最为丰富。石煤可作燃料，燃烧后的炉渣可制成炭化砖、水泥等建筑材料，还可从石煤中提取钒、铀、钼、镍、铜、钴等金属元素。 |
