| Abstract: | Through the detection and calculation of high confined ordovician limestone water on coal seam floor,prevention and control design of water was put forward by floor grouting method,which would promote the aquifuge intensity of coal seam floor.Water inrush phenomenon and quantity in working face are prevented and reduced,which ensured the safety production of coal mine. |
