| 摘 要： | 蒙古国煤炭资源丰富,但地质基础工作薄弱。位于蒙古国西部的胡硕图井田含煤地层为二叠系胡硕图组,为陆相三角洲体系沉积,含M1、M2巨厚煤层。根据煤质资料分析,区内煤类复杂,M1煤层以低灰、低挥发分、特低硫、高-特高热值、强黏结-特强黏结的焦煤（JM）为主;M2煤层以低灰、低挥发分、低硫、高-特高热值、中黏结-中强粘结的瘦煤（SM）为主;煤的变质作用类型以深成变质作用为主,同时存在动力变质作用。

| Abstract: | The Mongolia has abundant coal resources, but geological foundation works are rather shortage. Coal-bearing strata in the Husut minefield, western Mongolia belong to Permian Husut Formation, which is terrestrial deltaic system deposit, contains extra- thick coal seams M1 and M2. Based on coal quality analysis, coal ranks in the area are diversified, coal seam M1 is mainly low ash, low volatile matter, extra-low sulfur, and high to extra-high heat value, strong to extra-strong caking coking coal （JM）; while M2 mainly low ash, low volatile matter, low sulfur, and high to extra-high heat value, medium to medium strong caking lean coal （SM）. Coal metamorphism is mainly hypozonal, and dynamic metamorphism existed. |
