From February 195 1 to May 1952, he went to North Korea to resist aggression and defend the motherland. In the Korean battlefield of bullets, I worked hard and selflessly, and accomplished the tasks entrusted by my motherland well. Won the model worker award. His career was published in the July issue of Beijing Daily 1953. 1953 was admitted to China University of Mining and Technology (formerly Beijing Institute of Mining and Technology). During my school days, I was rated as "three good students", "excellent students" and "excellent league members" for many times. 1957 graduated from China University of Mining and Technology. After that, he taught in Xi 'an University of Science and Technology for a long time, and always taught and educated people with the spirit of serious responsibility and selfless dedication. He has taught professional courses, guided graduation design and graduation thesis for more than a dozen undergraduates majoring in mechanical engineering, electrical automation and mining engineering, and won the Advanced Worker Award twice. 1987 was awarded the honorary certificate of education for 30 years by People's Republic of China (PRC) and the Ministry of Coal Industry. Long-term active scientific research, the main research direction is mine hoisting theory and practice. The main papers are "On Reasonable Determination of Ascending Speed" published in Journal of Xi Institute of Mining and Technology, L1990; See for the calculation of emergency braking torque and oil pressure of hoist. 1987, mining machinery 1 1. The third issue of Mining Machinery 1986 published the reasonable determination of container anti-skid weight. Anti-skid Checking Calculation of Emergency Braking for Multi-rope Friction Hoisting was published in the 9th issue of Mining Machine 1983. On the mitigation of skip was published in the second issue of Shaanxi Coal Technology 1990; Selection and Calculation of Hoisting Wire Rope, Shaanxi Coal Science and Technology, No.2, 199 1. The above papers have won many excellent thesis awards. The anti-skid problem of multi-rope friction lifting and the determination of lifting torque are expounded in detail, and a set of calculation formulas are derived. Because of its accurate calculation and convenient use, it ensures mine safety and has great use value, and has been applied to teaching, design and production practice. Compilation of teaching material of Coal Mine Machinery in colleges and universities, the third article, Mine Hoisting Equipment, published by China Mining Institute Press1986; The first article in the book Selection Design of Mine Hoisting Transportation Equipment, Selection Design of Hoisting Equipment, was published by Xi 'an Mining Institute, 1983. 1984 delivered a paper at the national coal hoisting safety conference: analysis of rope breaking accidents in multi-rope friction hoisting and suggestions for improvement. 1986 published two papers at the national symposium on mining equipment: anti-skid checking calculation of multi-rope friction hoisting and braking torque calculation of hoist, which were well received. 1987 the reference material of graduation design in colleges and universities, the overlapping design scheme of multi-rope friction promotion, has been compiled as a teaching reference book in colleges and universities. Personal achievements won the honor of "China Contemporary Science and Technology Experts Festival"; Prosperous China; * * * and the backbone of the country; Who's Who in the World and other series.
