Abstract: The paper introduced the study and application of the limestone water control in Pingdingshan Mining Area.The regional control principle of the limeston e water was determine, the partition conception of the water inrush dangers were provided and the water inrush danger region could be divided into non water inrush da nger zone, water inrush threatened zone and water inrush danger zone.A platform was established for the regional control of the limestone water and a technical route t 0 regional control the limestone water was set up.According to the different hydrogeological element in Pingdingshan Mining Area, a plan to regional control the combin ed or signal limestone was set up.With the regional control, the water inrush accident from seam floor was effectively controlled and the mine safety production was real ized.
