胶结层对采金船开采砂金矿床的影响

Influence of glued layer on gold dredging in placer gold deposit

南方许多地区的砂金矿床存在对采金船开采影响极大的胶结层。它的分布范围广、胶结强度大、成片性强。本文根据生产矿山实例,探讨了胶结层的分布及地质特征,指出了胶结层对采金船开采的影响,介绍了胶结层的处理现状,强调了攻克这一难题的重要性。

Glued layer exists in placer gold deposits in the south of China which influences upon gold dredging greatly. It is widely distributed, intimately glued, easily grouped. On the basis of mining experience, the author has explored it's distribution and geological characteristics, pointed out it's influence on gold dredging, introduced current methods for handling it and emphysized the significance of solving this difficult problem on gold dredging.
