Long-term and continuous large-scale exploitation has increasingly exhausted shallow metal mineral resources,and deep mining has become inevitable.The current global status of deep mining of metal mineral resources was presented,a series of engineering challenges faced by deep mining were systematically analyzed,and some progress and future innovation focus in key engineering technologies,such as the prediction and prevention of rockburst,cooling techniques,rock support techniques,deep hoisting techniques,and several nontraditional deep mining techniques,were highlighted.Meanwhile,new insights into development strategies of deep mining technology were proposed.The integration of these forward-looking key innovative technologies will form the overall framework of an innovative technology system for the deep mining of metal minerals.This technology system will help to achieve safe,efficient,and green exploitation of deep underground metal mineral resources and ensure the sustainable development of the metal mining industry. 展开更多

China has achieved much during recent years in the area of lithospheric physics research and promoted the development of the geosciences (Teng, 2004). However, in the 21^st century, national needs and policy challenges the science of lithospheric physics. I suggest a general analysis, research, and development direction for lithospheric physics and point out clearly the content, core problems, and key scientific problems in this field. The realization of the earth and the discovery of the basic mechanisms of mountains, basins, minerals, and natural disasters depend basically on high-resolution observations of geophysics, the delineation of the fine structure of crust and mantle (2D and 3D) inside the lithosphere, substance and energy exchanges in the deep earth, the process of deep physical, mechanical, and chemical actions, and deep dynamical response. Therefore, geophysics should be the pioneer in the geosciences field in the first half of the 21^st century. I end with an analysis and discussion of some problems and difficulties in the research of lithospheric physics. 展开更多
