摘　　要：通过对底板高承压奥陶系石灰岩水的探测和计算,采用底板注浆的方法进行防治水设计,提高煤层底板隔水层强度,杜绝和减少工作面突水现象和突水量,保证了煤矿安全生产。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.
