Coalbed methane accumulates in synclines in the Qinshui Basin due to specific structural features. The South Anze No. 3 coal seam shows that gas-rich areas are found in synclines with specific folding patterns. The formation of these gas-rich areas is influenced by compression events in the past. Areas with shear fractures have lower methane content, while synclines with specific folding patterns have higher methane content. The main coal seam has been in an extensional environment, leading to methane dissipation. Surface water infiltration through specific channels also affects methane distribution.
