The invention relates to a preparation method and use of a carbon molecular sieve. The preparation method comprises the following steps: preparing a conventional carbon molecular sieve; and expanding the pores in the conventional carbon molecular sieve by using a secondary activation technique and modifying the conventional carbon molecular sieve by adjusting the pores. The new carbon molecular sieve is prepared by using coal, coconut shell or phenolic resin, and the like as raw materials, by the conventional production steps of crushing, forming, carbonizing, steam activating, hydrocarbon settling and shrinking and the like and by secondary activation with KOH or CO2 as an activator. The activation temperature is between 550 and 850 DEG C; and the ignition loss rate of the product is kept be between 0.1 and 30 percent. In aspect of use, the carbon molecular sieve can be used for absorbing nitrogen molecules and can also be used for absorbing and separating methane and nitrogen in seam gas under a variable pressure while achieving an adsorption dynamic separation effect and allowing high-concentration methane gas to be collected at the exit of an adsorption tower directly; and thus, the methane in the seam gas can be used efficiently.
