The Coal bed Methane Reservoir Numerical Simulation is a The Coal-bed Methane Reservoir Numerical Simulation is a

model of quantitative description founded by a variety of theories,

based on adsorption, diffusion, migration about gas and solid p, , g g

deformation, it used the depictive ability of mathematical language

to reshow the structure and function of CBM system and to image

the law of occurrence and migration about the fluid in coal seam

factually. Study on the Coal-bed Methane Reservoir Numerical

Simulation has important theoretical and practical significance to Simulation has important theoretical and practical significance to

guide production.
