摘　　要：绳索取芯钻进技术改变传统的提钻取芯过程,降低劳动强度,大幅度提高时间利用率、钻探效率及取芯质量。目前,绳索取芯钻进方法已经广泛应用于地质勘探、工程勘察和水文工程地质等多种要求采取岩芯的钻进工程中。本文结合云南某矿区勘察工程钻孔实例,通过小口径绳索取芯钻进工艺与普通取芯钻进工艺对比来说明其先进、高效的特点。The rope coring has changed the process of traditional coring, which can decrease the working intensity and evidently increase the time utilization, drilling efficiency and coring quality. At present, the rope coring has been widely applied to the coring of geological exploration, engineering exploration and hydrological engineering geology, etc. In this paper, taking the exploration engineering of an orefield in Yunnan as an example, we will show the advanced and high efficiency characteristics of small - hole rope coring according to the comparison between it and the common coring.
