Core drilling machine is a kind of geological core drilling equipment, which is mainly used for the survey and exploration of metal and non-metallic solid minerals. It can also be used in engineering geological exploration, hydrogeological survey, survey and exploration of oil and gas fields, and drilling drilling. The core drilling machine has three different technical characteristics of mechanical vertical shaft type, full hydraulic and electric top drive type. Drilling depth is 100-4000 meters in depth, occupies an important market share, and participates in drafting the industry standard of "geological core drill series" and "full hydraulic core drilling machine technical conditions".
