Core drilling rig is a kind of core drilling equipment. It is mainly used for general survey and exploration of metallic and non-metallic solid minerals. In addition, it can also be used for engineering geological exploration, hydrogeological survey, oil and gas field survey and exploration, and water well drilling. Because the core drilling machine needs to take out the more complete, non hybrid and non flex formation rock samples, so the core drilling rig is a rotary drill. According to the structure of the rotary driller, the core drill can be divided into three types: vertical shaft type, turntable type and movable rotary type.
