Drilling core cutting device for geological survey and drilling core cutting method using the same

摘要

The present invention relates to a drilling core cutting device for a geological survey and a drilling core cutting method using the same which easily divides a drilling core into two. The drilling core collects a core sample using a circular sampling pipe. More specifically, the drilling core cutting device can prevent damage to a core sample during drilling by collecting the core sample using the circular sampling pipe, and can cut only the sampling pipe which surrounds the core sample while preventing damage to the core sample. Thus, the drilling core cutting device can be used by being linked to drilling devices with various shapes. In addition, the drilling core cutting device can improve reliability in the results of an analysis of the drilling core by efficiently removing heat generated during cutting of the sampling pipe in order to prevent changes in characteristics of the core sample due to heat. Therefore, the drilling core cutting device can improve reliability and competitiveness not only in the fields related to technologies of storing the drilling core for a geological survey, but also in similar or associated fields.
