Professor Minggao Qian is the academician of Chinese Academy of Engineering, one of the first group of national distinguished young/middle-aged experts, member of the International Society for Rock Mechanics(ISRM) and International Bureau of Rock Mechanics(IBRM), the vice director general of China Coal Society, one of the first batch of gainers of the special subsidy offered by the State Council in 1990, the winner of the “Energy Award” of Sun Yueqi Science and Education Foundation affiliated to the China Foundation for Development of Science and Technology in 1994, and the winner of the national May 1st Labor Medal. Professor Qian is one of the main founders and exploiters in China on the subject of ground pressure and strata control. In the field of ground pressure, Professor Qian created a systematic and comprehensive theory, and founded the engineering theory system based on the core of both the strata movement law over stope and the “support-rock mass” system. Besides, the mechanics model of “Voussoir Beam” in the strata over stope and the law and perturbation theory of main roof breakage in rock mass put forward by him have been recognized at home and abroad. The scientific and technological achievements above exerted a significant influence on the development of coal mining.
