Abstract
⺠Microfractures form in unconfined coal samples after exposure to CO2. ⺠Fracturing caused by heterogeneous swelling and differential accessibility of coal macerals. ⺠Plasticisation is unlikely to play a significant role. ⺠In situ stress conditions during ECBM prevent microfractures to open or propagate. ⺠Permeability during ECBM operations will remain low.
