摘要
分析了矿岩散体中水存在的主要形式,阐述了矿岩散体流动性研究的重要性。分析了含水量对矿岩散体流动规律的影响,及其对细小颗粒散体摩擦力和粘结力的作用机理,得出了在放矿过程中,有效控制矿岩散体的含水量,是避免放矿堵塞和放矿大量贫化的重要结论。
In this paper,the form of water existing in the bulk ore-rock is analyzed,the importance of research on the flow property of bulk ore-rock is expounded.The influence of water content on the flow property of bulk ore-rock is researched.At the same time,the effect of water content on the fractional force and cohesive force between ore-rock granules bulk is also researched.A conclusion is drawn that optimum water content control of bulk ore-rock is helpful for a avoiding blockage and large ore dilution in ore-drawing.
