Abstract: In the mining process of coalbed methane, designing a reasonable mining process can reduce the coal seam damage
caused by the mining process, which is the key to improving the output of coalbed methane wells. This paper described the
characteristics of coalbed methane reservoir and its migration and production mechanism, and carried out the numerical simulation
of the productivity of low-permeability coalbed methane wells by Comet3 software.
