| Abstract: | 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. |
