摘　　要：长白地区地处吉林省东部山区,山高林密,地表大部被玄武岩覆盖,地质工作难度较大。应用瞬变电磁法,由于它观测精度高,不受高阻屏蔽的限制,对研究含煤盆地的分布以及断裂的分布起到了较好的效果。The Changbai area is located in the eastern mountain area of Jilin Province,with a dense mountain forest.The most surface in this area is covered by basalt;so,it is harder for geological working.Using transient electromagnetic method with high observation precision can be not limited by high resistivity shield,which may achieve a good result for studying the distribution of the coal basin and distribution of the fracture.
