Application of the split tube core barrel in the exploration of the Puxiong rare earth deposit in Jianshui, southeast Yunnan

More Information
  • 滇东南建水普雄稀土矿是一个超大型风化壳离子吸附型稀土矿床,矿体赋存于长岭岗碱性岩体的全风化层和半风化层中。不同于花岗岩风化壳离子吸附型稀土矿,该矿品位高,厚度大,用一般的浅井和赣南钻等取样工程无法揭穿稀土矿体。本文介绍了建水普雄矿区用半合管钻探工艺和浅井工程在相邻位置的施工情况。根据相同的取样层位和样品长度,对比了矿体的品位变化情况,利用品位的相对误差和正负偏差进行了统计,结果表明,单一对应样品品位相对误差合格率为100%;品位<0.07%的正偏差样品占样品总数的78.57%,负偏差样品占样品总数的21.43%;品位≥0.07%的正偏差样品占样品总数的52.17%,负偏差样品占样品总数的47.83%,正负偏差在可控范围内;单工程平均品位相对误差合格率为100%。说明半合管钻探工艺能够有效地应用于风化壳离子吸附型稀土矿勘查,实现资源评价。
