Notes:
A mathematical and numerical approach for the description of creep and failure of coal around a longwall is given. Two coal strata are considered. They are assumed to be elasto-viscoplastic. The variation in time of the stress and displacement around the excavation, as well as the limit thickness of the upper stratum which would avoid failure was found.
