21世纪的深地科学进入了新的发展阶段，深地科学规律尚未探明，深部工程活动普遍存在着一定程度的盲目性、低效性和不确定性，地球深部内源动力、结构演变规律、致灾机理等仍待进一步认知。因此首先从地球科学的视角定义了深地科学：以地球浅层以深的深层和超深层为研究对象，旨在探索地球不同层圈和不同赋存深度(深层和超深层)科学奥秘；理清了深地科学与地球科学的区别与联系：即深地科学是在已知地球科学知识体系上的延伸，是拓展科学视野、深化地球认知的国家战略科技方向，包含于地球科学；定义了深部与深地工程科学的本质：即针对现有浅部工程的科学规律与技术无法适用于深部工程的难点，探索深部工程相关科学规律，突破深部工程关键基础科学问题，匹配人类在深部工程活动中的地灾防控需求，进而指导深部资源安全高效绿色开发、深部工程空间有效利用。提出深地工程技术定义，即指人类为利用地球、开发地球所需要的工程实施技术与装备，为探索深地科学规律、开发深地工程必需的理论与技术手段。最后，进一步明确了深地科学的研究内容与规划，以及深地工程技术内涵与攻关方向(即深地工程岩土力学与灾变机理、超深井智能建造与能源资源高效开采、深地隧道与巨型洞室群智能建造、深地工程灾害智能防控与健康运维)，以期促进深地科学领域的发展。

Deep earth science in the 21st century has entered a new stage of development. The laws of deep earth science have not yet been explored. Deep engineering activities generally have a certain degree of blindness, inefficiency and uncertainty, and the endogenous dynamics of the Earth's deep part, structural evolutionary laws, and disaster-causing mechanisms need to be further cognised. Therefore, this paper firstly defines deep earth science from the perspective of geoscience: the deep and ultra-deep layers of the earth are the research objects from the shallow earth to the deep, aiming at exploring the scientific mysteries of the earth's different layers and different depths of the earth (deep and ultra-deep); clarifies the difference and connection between the deep earth science and the earth science: that is to say, the deep earth science is an extension of the known knowledge system of the earth science, and it is the national strategic science and technology direction to expand the scientific horizons, and to deepen the earth's cognition. It is a national strategic scientific and technological direction to expand scientific vision and deepen earth knowledge, which is included in earth science; it defines the essence of deep and deep earth engineering science: that is, for the difficulties that the existing scientific laws and technologies of shallow engineering cannot be applied to deep engineering, it is necessary to explore the relevant scientific laws of deep engineering, break through the key basic scientific problems of deep engineering, and meet the demand for geo-disaster prevention and control of human beings in the activities of deep engineering, and then guide the safe, efficient, and green development of deep resources and effective utilization of the space of deep engineering; at the same time, it further clarifies the difference and connection between deep earth science and earth science. This article proposes the definition of deep earth engineering technology, which refers to the engineering implementation technology and equipment required by humans to utilize and develop the Earth, as well as the necessary theoretical and technical means to explore the laws of deep earth science and develop deep earth engineering. Finally, to promote the development of deep earth science, the research content and strategic planning of deep earth science, and the connotation of deep earth engineering technology, have been further clarified (geomechanics and disaster mechanism of deep-earth engineering, intelligent construction and efficient mining, intelligent construction of deep-earth tunnels and giant cavern groups, intelligent disaster prevention and control as well as healthy operation and maintenance of deep-earth engineering).
