The Fdddy-Seis, a unique new type of geophone, has been adopted by artificial seism in geologic survey, oil and coal exploration.

The quantity of the secondary generated gas and the accumulation volume of coal-type gas were calculated, and the exploration prospective of coal-type gas was pointed out in this paper.

Based on coal resource features in eastern China and deep coal geological exploration faced difficulty and challenge analysis, discussed concepts of exploration area type and exploration mode.
