Abstract:

Infection zones of coal mining are favorable place to coalbed methane recovery in ground or gas extraction in underground.Based on gas practice of shaft,types of infection zones of coal mining were classified,numerical simulation methods of dynamic gas-content of coal seams in infection zones of coal mining were analyzed,and taking the second mine of Yangquan Coal Mine Combines as an example,dynamic gas-content of coal seams in infection zones of coal mining were evaluated.
