吉林省煤炭资源状况及其找煤潜力

吉林省煤炭资源主要赋存于侏罗系、白垩系，其次为石炭一二叠系、古近系和新近系，根据煤炭资源赋存特征可划分为七个含煤区带。截至到2007年末，全省保有煤炭资源储量20．4亿t，剩余服务年限不足15年。在19个主要生产矿区中辽源、浑江、舒兰、蛟河以及珲春等勘查程度较高，大多数老矿区外围和主要聚煤区带大部地区处于预查一普查阶段。通过分析提出实现找煤工作新突破的4个方向：①老矿区（矿井）的外围和深部找煤；②推覆构造下和玄武岩盖层下找煤；③松辽盆地西缘和东缘找煤；④东部山区勘查空白区找煤。

Status of Coal Resources and Look for Coal Potential in Jilin Province

Coal resources in the Jilin Province are mainly hosted in Jurassic, Cretaceous systems and secondly in Permo- Carboniferous, Paleogene and Neogene systems, 7 coal-beating zones can be divided according to the distribution of coal resources. Up to the end of 2007, the province possesses available coal resource reserves 2.04 billion tons; remaining length of service is fallen short of 15 years. In 19 main operating mining areas, the Liaoyuan, Hunjiang, Shulan, Jiaohe and Hunchun have higher degrees of exploration, most peripheries of old mines and main coal accumulating zones are just only in search for coal and reconnaissance stages. Through analysis, 4 orientations to realize coal looking new breakthrough have put forward： ① looking for coal in peripheries and deep parts of old mining area （mine）; ② looking for coal under nappe structure and basalt capping; ③ looking for coal on the west and east margins of the Songliao Basin; ④ looking for coal in exploratory barren areas in the eastern mountainous area.
