Controlled source audio magnetic telluric(CSAMT) is an effective approach to detect deep coal stratum in complicated-terrain mountain.

The permeability of rock samples collected from coal-bearing strata was tested on MTS 815.

Based on borehole data on the Genghuang exploration area,this paper analyzed sedimentary environment of coal-bearing strata and coal-forming conditions in the area,concluded that the coal-bearing strata are a depositional system that alternates between delta- dominated delta facies and tide-fiat facies of lagoon bay on the basis of regression.

Based on the AVO in the multi-technology in the field of exploration of coal and in the exploration analysis,establishing the model of the coal-bearing strata of the AVO,and analyzed,considering that the coal seam roof and floor reflected wave amplitude with the offset increasing.
