Professor Qian has published books 10, among which "Mine Pressure and Its Control" and "Coal Mining" won the Excellent Textbook Award of the State Education Commission, and "Surrounding Rock Control of China Coal Mine" won the second prize of the Seventh National Excellent Science and Technology Book. Published more than 1 10 papers.
Professor Qian has been teaching all over the world for the past 40 years. In 1962, the first graduate student majoring in mining engineering in China coal system was trained, in 1984, he was named the first doctoral supervisor majoring in mining engineering in coal system, and in 1987, he trained the first doctor majoring in mining engineering in coal system.
At present, 2 postdoctoral students have been trained, including 2 doctors 17 and 22 masters, of whom 2 were awarded the title of doctor with outstanding contributions by the state, and 1 won the Mao Yisheng Education Fund Award.
