摘要
针对经验公式的局限性，根据松散介质力学的极限平衡理论，提出了与松散介质的内摩擦角φ、粘聚力ｋ、松散介质沿壁面滑动的内摩擦角φ０相关的采场放矿漏斗口临界直径的计算方法。
In light of limitation of empirical formulas and according to the theory of limit equilibrium, the paper gives a calculation method for critical diameter of a discharge hopper, which is related to inner friction angle, φ and cohesive force, k of discrete media and inner friction angle, φ 0 at which discrete media is moving along wall surface.
