Draft:Chun'an Tang
| Submission declined on 1 June 2025 by NeoGaze (talk). This submission does not appear to be written in the formal tone expected of an encyclopedia article. Entries should be written from a neutral point of view, and should refer to a range of independent, reliable, published sources. Please rewrite your submission in a more encyclopedic format. Please make sure to avoid peacock terms that promote the subject. This submission's references do not show that the subject qualifies for a Wikipedia article—that is, they do not show significant coverage (not just passing mentions) about the subject in published, reliable, secondary sources that are independent of the subject (see the guidelines on the notability of people). Before any resubmission, additional references meeting these criteria should be added (see technical help and learn about mistakes to avoid when addressing this issue). If no additional references exist, the subject is not suitable for Wikipedia.

Comment: From the provided sources, it doesn't appear this person is notable enough. The vast majority of references come from the research of the person in question, which doesn't serve to establish notability. In addition, the tone of the draft is borderline promotional. Please add more reliable and independent sources in order to firmly establish the notability of the subject, as well as modify the most subjective parts for a more neutral point of view.

Chun'an Tang is a leading international expert in rock mechanics and born in 1958 in Hunan, China. Tang is dedicated to rock damage mechanics and innovation in fracture mechanics for deep tunnelling and mining applications, interpretation of large-scale geological processes in the earth, and effective controls of rock engineering disasters.
Biography
[edit]Tang is a Chair Professor funded by the Cheung Kong Scholar Programme from the Ministry of Education of the People's Republic of China.[1] He is the Director of the Deep Underground Research Center of Dalian University of Technology. He was also the Vice President of the Chinese Society for Rock Mechanics & Engineering[2], and was the Chairman of the China National Group of the International Society for Rock Mechanics[3][failed verification]. He was the chief scientist for the National Key Fundamental Research and Development Program of China in rock engineering disaster modeling and prediction. In 1984, he started his Ph.D. research in Northeastern University (China) and got his Ph.D. in 1988.[1] In 1991, he continued his post-doctoral work in Imperial College London, UK. Then, as an academic visitor, he had lots of experience working in Canada, Sweden, Singapore, Switzerland and Hong Kong (China). He was on Elsevier's "Highly Cited Chinese Researchers" for eight consecutive years.[4][failed verification]
Creative Activities in Applied Science and Engineering Practice
[edit]Tang established an elastic-brittle statistical damage constitutive equation of heterogeneous, discontinuous rocks, and invented a Rock Failure Process Analysis (RFPA) method, in which Monte Carlo generation of variable mechanical parameters is combined with an elastic-brittle statistical damage constitutive model, such that the nonlinear system in macro-scale can be transformed into a linear heterogeneous system at meso- and microscale,[5] accomplishing the simulation of complex nonlinear deformation and failure processes. This software is internationally accepted and widely used in mining, hydropower, transportation, and other geotechnical projects. Successful applications of RFPA to major Chinese projects include the slope stability analysis of Yalong River Jinping Hydropower Project. It has found use in many international projects, including pillar failure and rock burst modelling.

Tang's simulation of observations of polygonal cracks impacting the human environment[6][7], including drought-land, cooled ceramics, and weathered frescoes, directly impacted the science and engineering behind geothermal heat transfer and extraction by providing a model for internal fractures and flow within the heat source rock. He then proposed the hypothesis that heating inside the Earth lithosphere, caused the Earth lithosphere to expand continuously and eventually break up, becoming the origin of early plate tectonics[8][9]. He also received acclaim[from whom?] for his innovative interpretation of the evolution of the Grand Canyon.[10]
In pursuit of clean energy applications, Tang led China's new proposal to geothermal energy extraction. Different from the current hot dry rock Enhanced Geothermal System (EGS), based on drilling technologies, where water consumption, chemical pollution, induced earthquakes, and low productivity remain the main challenge, this innovative approach utilizes deep mines for Excavation-Enhanced Geothermal System (EEGS)[11]. This concept introduces an underground hot water heat energy reservoir and transfer hub. With large diameter shafts connected the reservoir, the flow rate through the shaft can be orders of magnitude greater than through drill holes, hence potentially improve geothermal energy extraction efficiency.[11]
