文摘According to the mining mechanisms of CBM combined with coal structure andthe key technologies of coordinated mining coal and coalbed methane under differentmining coal models, the theoretical foundation of coordinated mining of coal and coalbedmethane was expounded, and the mining models of coordinated mining of coal andcoal-bed methane were classified.This research can provide a reference to safety productionof coal mines and development of CBM resources.
