| Abstract:The Tibet Autonomous Region Jiama Copper Polymetallic Deposit 3000m Deep Scientific Drilling Project is the first 3000m scientific drilling project for solid mineral survey in the Qinghai—Tibet plateau area. The project is executed to characterize in detail formation alteration and mineralization information within 3000m， and provide a solid foundation for the study of the metallogenic theory and the establishment of the deep exploration model. In view of the project purposes， and taking into account of the site inspections and the geology in the mine， HXY—8VB type core drill rig with the K type derrick is proposed， together with the 5—tier borehole structure and multiple drilling processes including conventional core drilling， wireline coring and reaming and conventional wireline coring, so as to provide a guarantee to improve drilling efficiency and drilling quality． |
