A System Dynamics Model of Flooding Emergency Capability of Coal Mine

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
