1, lyna has been working in the front line of coal production and scientific research for a long time, with rigorous style of study, good at integrating theory with practice, innovative spirit and team spirit, and 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.
2. 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 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.
3. 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.
4. Academician lyna has been working in Huainan Mining Group since he graduated from 1982. He has accumulated a lot of field work experience and achieved rich theoretical results. More than 60 papers have been published, of which 9 have been retrieved by EI and 3 have been published. During my work in Xie Yi Coal Mine, I was responsible for the mining area (section) design of the whole mine, and presided over the design of 14 mining area. Among them, the design of lower liberated seam mining, group A coal mining and coal pillar mining in Xiesan Mine achieved obvious economic benefits, which not only ensured the safe production of the mine, but also extracted more than 3 million tons of coal.
In his work, he always insisted on popularizing and applying new products, new technologies and new processes, and organized and completed a number of scientific research projects. It also vigorously promoted the scientific and technological progress, developed mechanization, and actively carried out the reform of coal mining methods and roadway layout, making contributions to the realization of the world's first million-ton fully mechanized mining team. After optimization, Zhangji Mine was completed within five years, and the investment and engineering quantity were more than doubled compared with the original design.
6. He seriously organized scientific research to tackle key problems. During the Ninth Five-Year Plan, he solved the technical problems in the mining area and achieved the goal of ensuring safe production and improving efficiency in the mining area by relying on scientific and technological progress.
