炼焦煤在隔绝空气条件下加热，能软化形成胶质体并结为焦炭的烟煤。分类和特性根据煤的变质程度和粘结性参数，中国于1958年将煤分成十大类，其中属于炼焦用煤范围的有四大类,即气煤、肥煤、焦煤和瘦煤,有关指标如下：气煤变质程度较低，挥发分较高，受热软化时胶质体量少，热稳定性差。在形成半焦之后，由于热缩聚剧烈，收缩较大，又因它的气孔率大、气孔壁薄，难于抵抗收缩应力，所以单独用气煤炼成的焦炭，裂纹多且深，焦块细而脆（气煤中的2号肥气煤，粘结性较好,可以单独炼焦）。气煤在炼焦配煤中可起减小膨胀压力和增大焦饼收缩的作用，并可提高焦炉煤气和炼焦化学产品的产率。肥煤变质程度比气煤稍高，受热时能产生大量的胶质体，因此具有很强的粘结性，而且流动性和热稳定性都好，是炼焦配煤中的重要成分。用肥煤单独炼焦时，焦炭熔融好，强度高，但横裂纹多，气孔率较高，焦饼中心有海绵焦。焦煤变质程度比肥煤又稍高，具有中等挥发分与中等胶质层厚度。单独炼焦时能形成热稳定性很好的胶质体，而且半焦收缩较小较慢，因此能得到气孔率较低、粒度大、裂纹少、机械强度高的焦炭，但焦煤在成焦过程中膨胀压力大，容易造成推焦困难。全世界的焦煤储量有限，在炼焦配煤中务须节约使用。瘦煤变质程度较高，挥发分较低，受热时产生胶质体少，半焦收缩小。用它单独炼焦时,焦炭粒度大,裂纹少，但熔融性差，不耐磨。瘦煤在炼焦配煤中起减少焦炭裂纹并增大粒度的作用。配煤炼焦煤料主要由上述各种煤按适当比例配合而成。炼焦配煤的原则是：节约优质炼焦煤，合理利用资源；在各种煤之间取长补短，以求获得质量合格的焦炭。当前中国炼焦配煤是以焦煤和肥煤为基础，适当配入气煤和瘦煤，尽量配入本地区的弱粘结性煤。扩大炼焦煤源的新途径中国炼焦煤资源虽较丰富，但分布不均衡，大部分地区气煤储量多，而焦煤和肥煤较缺。必须合理利用并扩大炼焦煤源，主要途径为：捣固炼焦、配型煤炼焦、预热煤炼焦、型焦。
