Abstract:The coal mine water of K2 from roof and O2 from floor was one of all great hazards threaten the safety production in tuan-bai coal mine.The primary characteristics analysis of the water-control of ordovician limestone water was made,and the water-inrush forecast model was established to predict the water inrush from floor ordovician limestone water of tuanbai coal mine.It has a guide significance to the mine production design and preventive and treatment water.
Key Words:Ordovician limestone karstic water,The floor water hazard,Prediction model
