| 摘 要： | 本文根据煤深成变质的现代理论，采用地质一煤质结合的方法，定量地评价了淮南矿区煤的深成变质作用，从而对深部煤质作出初步预测。成果表明，淮南矿区煤深成变质的阶段性和回返期后的变质作用相当显著；在由浅到深的可采深度范围内，存在着由低级烟煤到高级烟煤构成的垂直分带。据此推测，淮南煤田并不是单一煤种（气煤），更可能是一个赋存着多种煤类的烟煤区。

| Abstract: | On the basis of modern theory of hypzonal metamorphism,and the method with both geology and coalquality into consideration,the hypozonal metamorphism of coal in Huainan coal district was quantitatively estimated anda prediction made for deep seated coal quality.Results show that the post orogenic metamorphism in Huainan coal dis-trict was quite distinct;Within the range of workable deepness from the shallon to the bottom,there existed a verticalzonation of bituminous coal from low rank to high rank.Therefore,it was deduced that the Huainan coal district wasa more possible host of many typos of coal rather than a simple type of gas coal. |
