小倾角钻探工艺技术在绿色勘查中的应用

Application of small angle drilling technology in green exploration

摘要:

以钻代槽是覆盖区解决矿产勘查与生态环境保护间矛盾的有效技术手段，针对目前浅层取样技术在覆盖区应用过程中存在的问题，综合国内外先进的地表勘查用便携式取样钻探设备和工艺技术方法，结合生态文明建设和绿色勘查的要求，开展小倾角（≤30°）钻探工艺技术研究，采用全液压便携钻机、铝合金底枕、锚管固定、泵送内管总成和打捞器取心、跟管护壁、全倾角测斜等相结合的钻探工艺技术方法，并取得成功应用。

Abstract:

Replacement of trenching with drilling is effective technical means to solve the conflict between mineral exploration and ecological environment protection in the overburden zone. In view of the problems with shallow sampling technology in the overburden zone, with review of the advanced portable sampling drilling equipment and technology for surface exploration at home and abroad, and taking into account of the requirements of ecological civilization construction and green exploration, small angle （≤30°） drilling technology has been researched and applied successfully.
