Don't hurt!Superstar fall

A mining engineering expert, an academician of the Chinese Academy of Engineering, and a professor of Chinese Mining and Technology University (Beijing), Qian Minggao, died in Beijing on September 23, 2022 in Beijing.

Qian Minggao was born in Wuxi City, Jiangsu Province in December 1932. He graduated from Northeast Institute of Technology (now Northeast University) in 1954. Former associate professor, professor and doctoral supervisor of the Department of Mining Engineering of China University of Mining and Technology, director of the Department of Mining Engineering, etc. In 1995, he was elected academician of the Chinese Academy of Engineering.

Qian Minggao is one of the main founders of my country's mines and rock -formation control disciplines. In the early days of the founding of New China, the cause of mining science in my country was almost blank. In response to the national call, Qian Minggao, who had obtained the mechanical department, took the initiative to transfer to the mining department. , I just feel that the more difficult majors, the more hopeful to make achievements. "

During decades of scientific research, he mainly engaged in the research of mines and rock formation control, and proposed the "masonry balancing hypothesis" of the rock layer on the field and the rules of the old top break and the disturbance caused by the rock body when breaking the rock body. Theory; created the "masonry beam" mechanics model; the engineering theoretical system with the law of covering the rock layer and bracket-enclosure system as the core of the collection of rock layers on the field, and established a practical engineering technology for "mining pressure prediction, control and monitoring" ; Put forward the key layer theory of the rock formation control and the "green mining technology" system that is in line with the scientific concept of development.

Qian Minggao focused on scientific research throughout his life, and once warned students: "It is necessary to engage in scientific research, have a rigorous study style, ambitious, can bear loneliness, work hard to do things, and avoid impetuousness."
