Abstract: The paper mainly discusses the geochemical characteristics and types of the typical coal-typeg as pools of the Upper Paleo zoic, the tectonic environments and exploration prospects in China. North China coal-accumulating area is the most favourable area. Two kinds of tectonic environments and four types of coal-type gas pools have been concluded, self -generated self-reservoired type of ancient burial hill( Suqiao type) and paleogenerated neoreservoired type (Wenliu type ) in tectonically active rift region, combination type ( Ordos type) and self-generated self-reservoired type in tectonically stable region of craton. The four types above should be the major types for exploring coal-type gas in the areas. The coalbed gases are also briefly discussed in the two kinds of tectonic environments.
