%X Based on the analysis of desorption velocity and the capable desorption quantity of coalbed methane, we systemically discussed the desorption characteristics of coalbed methane of Panzhuang Coal mine and analyze the relationship between desorption velocity and desorption time , and the relationship between the capable desorption quantity and the burial depth of coal reservoir. In the area, there is quite high capable desorption rate in the middle area of the first mine field, most area of the fifth coal of the second mine field and the north area of the third coal of Panzhuang Coal mine, which is propitious to the exploitation of coalbed methane. In the layer region, the capable desorption rate mostly takes On a negative relationship with the increase of burial depth of coal reservoir, but the data is comparatively discrete.
