传统的找煤方法不论何期的含煤岩系多以现今保留的盆地边缘为目标，作者通过近年对松辽盆地东缘和长春双阳地区的研究认为：新的找煤战略应广泛开展盆地外围第四系覆盖的、根据零星露头误圈入老地层中的残留煤盆地的寻找，同时注意现今盆地边部向盆地内已尖灭的煤系地层，在盆地的更深部可能存在另一个独立的含煤小盆地。
The traditional coal-finding method Regardless of the coal-bearing rocks in the coal mines, most of them are aimed at the margins of the basins they retain today. Based on the recent researches on the eastern margin of the Songliao Basin and the Shuangyang region of Changchun, the authors believe that the new coal-seeking strategy should be widely implemented around the periphery of the basin Quaternary cover, according to sporadic outcrop accidentally circle into the search of the remaining coal basins in the old formation, while paying attention to the coal-bed strata that have been extinct in the basin to the present basin edge, there may be another independent Coal-bearing small basin.
