深地科学领域的若干颠覆性技术构想和研究方向

President Xi Jinping has recently declared that marching toward the deep earth is a strategically scientific and technological challenge we must overcome.In China,the exploitation of deep earth resources has become an important direction for the future development of science and technology.Unfortunately,there is little knowledge available about the nature of the deep earth so far.Many research organizations,such as ICDP and GFZ,have been carrying out research regarding the nature and basic laws of the deep earth.Therefore,it is extremely critical to plan in advance,control the high ground of research,and promote the fundamental and frontier researches.In this paper,the inevitable trend of the exploitation of deep earth resources and utilization of deep underground space was extensively analyzed from the point of view of deep earth energy and human survival.Three research issues regarding moving into the deep earth were proposed,namely,the detection of deep geological structures,the study of the basic laws of deep underground behavior,and the utilization of deep underground space and resource exploitation.By focusing on the state long-term strategies for the deep underground resource exploitation,energy reserve and nuclear waste disposal,three disruptive idea and technologies related to the research of deep earth were proposed,namely,the fluidized mining of deep underground mineral resources,the utilization of deep underground space and the construction of underground cities,and the design of deep underground laboratories and ecological living capsules.Finally,by focusing on the cutting-edge studies of deep underground rock mechanics,the fluid mechanics of deep underground porous media,deep underground seismology and geophysics,and deep underground microbial energy traceability,a few key points of deep earth research were addressed,which are in-situ fidelity coring technology;non-conventional rock mechanics theories;transparentization and visualization methods for deep underground geological formations and mining processes;deep underground seismology and geophysics;deep underground microbiology;deep underground mining and energy storage;deep groundwater storage;migration and quality conservation;underground space ecology and energy circulation system;etc.Based on the breakthrough of the disruptive ideas and technologies of some significant research areas,a world-leading scientific base for deep earth research with a Chinese characteristic can be formed.
