摘要
溜放粘结性矿料时常会出现两类放矿障碍,一类是稳定粘结拱卡堵,另一类是形成管状流动。本文论述了放矿障碍产生的原因和形式,以及防止产生放矿障碍的措施和有效出矿口尺寸的计算方法。
There are two kinds of hindrances to cohesive ores during ore drawing. One of them is stable stick arch and the other rathole flow. In this paper the mechanism involved in these hindrances is revealed and the possible forms in which the hindrances engender discussed. Furthermore, formulas are developed for calculating the critical outlet size.
