Lyna has been working in the front line of coal production and scientific research for a long time. He is rigorous in study style, good at integrating theory with practice, full of innovative spirit and team spirit, and has strong engineering organization ability. He presided over the completion of major national key scientific and technological projects and made great contributions to the scientific and technological progress of Huainan mining area and coal industry. Its main achievements and contributions are as follows: based on the mining conditions of low permeability and high gas seam in Huainan mining area, the technical principle of gas drainage by pressure relief mining is creatively put forward, which successfully solves the technical problems of safe mining in Huainan mining area and puts forward the technical principles that should be followed in the design of high gas mine for the first time; On the basis of optimizing the gas drainage technology of pressure relief mining, the principle of co-mining technology of coal and gas without coal pillar (roadway protection) is creatively put forward, and a set of complete technologies with independent intellectual property rights is developed. Organize and complete a number of research on surrounding rock control technology of soft coal and rock roadway, and solve the technical problems of soft coal and rock roadway support in Huainan mining area; The popularization and application of the research results in the coal industry has produced remarkable social and economic benefits, and made important contributions to the development of coal and gas co-mining technology in low-permeability coal seams in China and even in the world. In 2005, the National Engineering Research Center for Coal Mine Gas Control was established with the approval of the state, which has become an important base for scientific research, industry training and technology promotion in the coal industry.

He is the winner of the first "Outstanding Youth Science and Technology Award" and "Energy Award" of Sun Science Education Foundation of China Science and Technology Development Foundation, and won the Anhui Major Science and Technology Achievement Award in 2006; Young and middle-aged experts who have made outstanding contributions to the country and top-notch professionals in China's coal system are awarded by the Ministry of Personnel and enjoy special government allowances from the State Council. Since 2007, lyna has obtained 9 national invention patents; He has successively won five second prizes for national scientific and technological progress (ranked 13 and 32nd), six provincial and ministerial special prizes and first prizes (all ranked first), published more than 40 papers (including 9 EI) and published 3 monographs. Since 2005, he has put forward the key technology of co-mining of coal and gas in low permeability coal seam without pillar (roadway protection), which is considered as a major breakthrough in coal mining technology. The project won the special prize of China Coal Industry Science and Technology Award in 2008 and the second prize of National Science and Technology Progress Award in 2009, and was listed as the national key promotion technology achievement by the National Development and Reform Commission. 2011.10/-"Outstanding Contribution Award of World Mining Congress",
