According to the official Weibo account of Guangming Daily, Qian Minggao, an expert in mining engineering, an academician of the Chinese Academy of Engineering, and a professor at China University of Mining and Technology (Beijing), passed away in Beijing on September 23, 2022, due to an illness from which he could not be cured. Public records show that Qian Minggao was born in December 1932 in Wuxi, Jiangsu. He served as an assistant instructor and lecturer at Beijing Mining Institute, as well as a lecturer and associate professor at Sichuan Mining Institute. He held positions as associate professor and professor at China University of Mining and Technology, and was also the head of the Department of Mining Engineering at the same university. In 1995, he was elected an academician of the Chinese Academy of Engineering. Qian Minggao is one of the main founders of the discipline of mine pressure and strata control in China. In the early years of the People’s Republic of China, the field of mining science in our country was virtually non-existent. In response to the call, Qian Minggao, who had already been admitted to the Department of Mechanical Engineering, voluntarily transferred to the Department of Mining. “At that time, I was not familiar with coal mining, nor did I know much about the complexities of this discipline; I simply believed that the more challenging a field was, the greater the chances of achieving success in it.” ” Qian Minggao is one of the main founders and pioneers in the field of mine pressure and its control in China. He has made systematic, comprehensive, creative achievements and important contributions to the development of the discipline of mining engineering, as well as in the theory and practice of mine pressure ； The proposed \"masonry beam equilibrium hypothesis\" for the overlying rock strata in the stope, along with the theory of the failure pattern of the roof and the disturbances it causes in the rock mass during failure, have had a significant impact both domestically and internationally ； The established mechanical model of \"masonry beams\" has been included in the relevant entries of the \"Encyclopedia of China: Mining and Metallurgy\" section, and it is incorporated as a fundamental theory into textbooks, being widely adopted by higher mining institutions ； An engineering theoretical framework centered on the movement patterns of the overlying rock strata in the mining face and the support-rock mass system was developed, and practical engineering techniques for \"prediction, control, and monitoring of mine pressure\" were established, contributing to safe coal production as well as efficient and high-yield mining. Including Qian Minggao, the Republic has lost 27 academicians of the two academies this year.
