    摘要: 本文阐述了工程地质勘察钻探取样方法是地质环境勘察的关键环节。全面对比了勘察钻孔结构设计,钻进方法选择、钻探技术及操作方法和钻进工艺的差异性,详尽分析钻进方法、技术和工艺的优劣,最大程度地简化优化钻孔结构,以提高钻进效率和降低钻探成本。为地质环境勘察、水文地质调查、矿产资源勘查等地质调查取岩芯样,获得基础参数,提供了重要的取样方法理论依据。This paper describes that the engineering geological exploration drilling sampling method is the key in the reconnaissance of geological environment. Differences of the survey and drilling structural design, drilling method selection, drilling techniques and methods of operation and drilling technology are comprehensively compared, and drilling methods, techniques and technology advantages and disadvantages are analysed in detail. The drilling structure is optimized to improve drilling efficiency and reduce drilling costs. This paper provides an important theoretical basis for the sampling method in order to get coring samples for geological environment survey, hydrogeological investigations, and other mineral resources exploration, and to obtain basic para- meters.
