| Abstract: | 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. |
