【Abstract】 The passage of water*.inrush from floor has the characteristic of maximal smoothness in inner wall when the passage is a fault or a subsided*.column and the water*.inrush quantity gets maximum.The model of round and smooth tube is built to calculate the maximal water inrush quantity.On the basis of the theory of flow mechanics,the non*.liner formula for predicting the maximal quantity of water*.inrush from floor is induced,which shows the non*.liner influence of underground pressure to maximal quantity of water*.inrush.The applicability of the formula is tested by an example.更多还原
