| 摘 要： | 新疆阜康大黄山煤矿位于准噶尔盆地南缘乌鲁木齐山前坳陷东段，多项煤变质指标分析结果表明：该区煤变质程度沿煤层走向分带较为明显，沿煤层倾向上煤变质程度虽未突变，但挥发份却随深度加深明显减少．结合煤矿区域构造特征，煤层的变质以深成变质作用为主，动力变质作用为辅．同时推测深大断裂有利于隐伏热异常形成，它的多期次活动可为地下水从地壳内部获得热量提供通道，并为煤层变质提供热源． |

| Abstract: | The Dahungshan coal mine in Fukang city of Xijiang located in the east of Urumqi piedmont depression, the south edge of Junggar basin. Analytic results show that the coal metamorphic zonation is clear horizontally.On tendency the coal metamorphic grade do not mutate, but the volatile compound in coal obviously decrease downwards. Combined with tectonic setting of coal mine district, deepseated metamorphism is the most important in coal metamorphism, followed by the dynamic metamorphism. The discordogenic fault is presumed to be of advantage to the forming of hot abnormality and their multistage activities can provide the passages through which circulated groundwater acquire the heat for coal metamorphism from deep crust. |
