It is of great significance to carry out intermediate-depth and deep ice-core drilling projects in polar regions for obtaining paleoclimate information and predicting future ice sheet evolution. Since the 1960s， countries around the world have completed 26 intermediate-depth ice-core drilling projects and 14 deep ice-core drilling projects in polar regions. At present， there are still five deep ice core drilling projects in progress， which are Dome A， Beyond EPICA， MYIC， Dome Fuji and Hercules Dome. Russia is also planning a deep ice core drilling project at Dome B. At present， China has only implemented one intermediate-depth ice-core drilling project， and the depth of the deep ice-core drilling project has just broken through 800m. Compared with Europe， the United States， Japan， Russia， China has less drilling experience， low degree of equipment independence， and relatively backward technical level in the field of intermediate-depth and deep ice-core drilling technology. Therefore， China should actively develop deep ice-core electromechanical drill with independent intellectual property rights， accelerate the implementation of Dome A deep ice-core drilling project， carry out intermediate-depth ice-core drilling and ancient blue ice drilling projects， break through key technologies such as rapid ice drilling and directional ice-core drilling technology， so as to promote the development of China’s polar ice-core drilling technology and improve its influence in the field of polar ice core science.
