Flooding emergency capability of coal mine is influenced by personnel’s emergency quality, rescue equipment, rescue materials, rescue team and emergency management. This paper sets up a causal diagram and a flow chart model. With investigation on coal enterprises, a simulation model of flooding emergency capacity of coal mine is established using system dynamics. Results show: at the early stage of coal mine production, emergency input has hysteretic nature; increasing emergency input improves each factor’s emergency level and flooding emergency capacity of coal mine; initial emergency level affects the time flooding emergency capacity reaches to desired level; the impact of each factor on flooding emergency capacity is different. The simulation model helps a sense of emergency input direction scientifically for coal enterprises. It is good for improving flooding emergency capacity of coal mine.

W artykule przedstawiono model matematyczny system ostrzegania przed powodzią w kopalniach. Przeprowadzono symulacje z uwzględnieniem dynamiki procesu.
