Abstract: From prevention needs of limestone aquifer in Pingdingshan Coal Mine, formula of water inrush coefficient and Slisalif's are selected as criterion respectively, and then the idea of limestone aquifer water inrush danger division taking the mine water inrush danger division and mining face water inrush risk assessment as the core is offered, which builds a platform for the limestone water regional governance. Based on dividing hydro-geological units, the water inrush danger zones of the first and second coal beds are divided. Aimed to water inrush danger of different units and combined with hydro-geological characteristics, the paper determines principle, target, thinking of regional governance respectively, governance engineering is planned.
