| 摘 要： | 针对槽探施工面临的环境破坏及深度局限性问题,本文提出了以钻代槽技术新方法,并在海南峨麻岭矿区进行试验。通过在槽探拟施工区域,根据产状或覆盖层情况,布置间距小于10m的钻孔,获取基岩,来完成对矿体的评价。结果表明,获取的岩石样品资料可以很好地与槽探实物资料相吻合,证实了以钻代槽勘查技术方法是可行的,有效的。

| Abstract: | In order to solve the problems of environmental damage and depth limitations in trenching projects, this work proposed a new method in which shallow drilling is used to replace trenching. It has been tested in the Emaling gold deposit of Hainan. In the planed trenching area, according to the rock occurrence, drill holes were arranged with spacing less than 10 meters. Rock samples were collected from these holes and analyzed to complete the evaluation of the orebody. The results show that the data of obtained rock samples by drilling is consistent with the real data from previous trenching, which proves that the technique with drilling substituted for trenching is feasible and effective. |
