摘　　要：使用高精度电磁频谱探测方法,对滇东恩洪、老厂地区的煤层气作实地探测。取得煤系地层中的地球物理响应。由此建立煤层、围岩的岩性与物性的关系,进而利用大地电磁频谱探测技术了解煤层的埋深、厚度。使煤层气的勘探工作有了新的科学勘探技术方法。The seam gas of Enhong, Laochang area in East Yunnan has been explored on the spot with the high-precision electromagnetic frequency spectrum method, which has got the geophysical response in the coal measure strata. The relationship between lithological character and material quality of coalbed and wall-rock has been established. And the depth and thickness of coalbed are explored with the telluric electromagnetic frequency spectrum prospecting method, which introduces a new scientific method to the exploration of seam gas.
