摘　　要：永夏煤田赋存了丰富的煤炭资源，是我国六大无烟煤生产基地之一，但区内各种类型的岩浆岩体以不同的形态侵入到各煤系地层，使煤层造成分岔、变薄或完全吞噬，破坏了煤层的连续性。同时，由于受岩浆高温气、热液的烘烤，在煤层的不同部位形成不同变质程度的天然焦、天然半焦，降低了煤的工业利用价值。开展该区煤及天然焦的进一步研究工作，对其客观存在的天然焦这一宝贵资源，做到合理开发利用，势在必行，意义重大。Coal resources occurrence of the Yongxia coalfield is quite rich, it is one of the six large production bases of anthracite in China. But the continuity of the coal seam is destroyed by invading of various types of magmatic rock with different shapes. At the same time, the industrial value of the coal is reduced because of the high temperature vapor and hydrothermal baking of magmatic rock. It has a great significance and imperative to carry out the further research and reasonable comprehensive exploitation of the coal and natural coke.
