摘　　要：通过对采金船挖斗给受矿漏斗供矿时漏矿原因的分析认为：采取改变挖斗开口形状、调节卸矿时的冲洗水压和水量、缩短斗链与受矿漏斗间的相对距离等措施，可把漏矿损失减少到最低程度。同时，强化漏矿回收的选别工艺也是解决漏矿问题的重要措施。Through analysis of the causes of the spillage from dredger buckets when feeding the receiving hopper, it is indicated that the spillage losses could be reduced to the minimum taking such measures as changing the bucket opening form, adjusting the pressure and flowrate of flushing water during ore discharging, shortening the relative distance between the bucket chain and receiving hopper, etc. It is also of importance to improve the dressing process for intensive recovery of the spilled ore.
