Numerical simulation of coalbed methane geologic evolution history;

The paper has quantitatively studied the evolution history of coalbed methane(CBM) of main coal seams in Liulin Mining Area of Hedong Coalfield by using numerical simulation method.

Based on the study about vertical seal mechanism and evaluation standard of faults,and according to the analysis of evolution law of vertical seal of faults and the influence factors,a method studying evolution history of vertical seal of faults has been established.

It also probes into the evolutionary history of the zone and elaborates the operation significance of searching for coal resource of Mesozoic era.
