    摘要:

    地表基质取样是开展地表基质层调查必不可少的工作环节,笔者等在浅地表层钻探技术的基础上,结合浅覆盖区矿产勘查、地球化学勘查、区域地质填图、环境调查、工程勘查、考古调查等领域钻探技术应用现状,根据不同地表景观及基质类型条件下的钻探取样需求,梳理了岩石、砾质、土质、泥质等地表基质钻探取样技术要点,研发了电动背包式钻机、Ф60/40mm单管冲击钻进、Ф50mm双管冲击钻进、Ф208mm中空螺旋钻进等取样器具及配套钻进工艺,在北京、内蒙古巴彦淖尔、浙江宁波、西藏那曲等地区开展了野外试验应用,通过获取满足要求的样品,很好的揭示了地层信息及物质组成,进一步在实践中提出了不同种类地表基质钻探取样技术方法,为建立自然资源调查监测体系及地表基质层调查工作提供钻探技术支撑。

    Abstract:

    Surface substrate sampling is an essential link in surface substrate survey. On the basis of shallow surface drilling technology, in the light of the current situation of the application of drilling technology in the fields of mineral exploration, geochemistry exploration, regional geological mapping, environmental investigation, engineering exploration, archaeological investigation, etc. in shallow overburden areas, according to the requirements of drilling and sampling under the conditions of different surface landscapes and substrate types. The key points of surface matrix drilling sampling techniques such as rocks, gravels, soils and argillaceous materials are summarized, the sampling technology and apparatus of electric knapsack drill, Ф60/40mm single- pipe percussion drilling, Ф50mm double- pipe percussion drilling and Ф208mm hollow spiral drilling were developed. Field experiments were carried out in Beijing, Bayannur in Inner Mongolia, Ningbo in Zhejiang province and Naqu in Tibet Province. By obtaining samples that meet the requirements, the formation information and material composition are well revealed. Further, different types of surface substrate drilling sampling techniques have been proposed in practice. It provides drilling technical support for the establishment of Natural Resources Investigation and monitoring system and the investigation of surface substrate.
