Summarized the main factors which affect the pumping rate of coal seam and analyzed domestic and international coal-bed methane extraction techniques conventional ground conditions based on the detail studies about the recent research status and then introduced two kind of extraction technology. On this basis,proposed the new kind method which based on the nature mechanism of the coal (rock)seams influenced by the cycle freezing and thawing and introduced this deformation and failure mechanism into the ground extraction to increase the permeability in order to provide a new direction for the low permeability coal-bed methane extraction technology.
