Core drilling rig is a type of core drilling equipment. It is mainly used for the general survey and exploration of metal and non-metallic solid minerals. In addition, it can also be used for engineering geological survey, hydrogeological survey, general survey and exploration of oil and gas fields, and water well drilling. Since core drilling rigs require the removal of relatively complete, unmixed and non-distorted formation rock samples, core drilling rigs are all rotary drilling rigs. According to the structural form of the drilling rig rotor, core drilling rigs can be divided into three categories: vertical shaft type, turntable type and mobile rotor type.
