Zhang Jincang: Strive to expand the boundaries of knowledge a little bit

On June 11, the "China Coal Daily" published an exclusive interview with Zhang Jincang Wang, an associate professor of the Chinese University of Science and Technology of the Seventh Youth of the Chinese Association for Science and Education, and Zhang Jintong, an associate professor of the School of Energy and Mining, China University of Mining and Technology. Scientific research exploration story.

With a computer bag and wearing a windproof suit, the 7th young talent of the Chinese Association for Science and Technology of China, Zhang Jintang, an associate professor of the 32 -year -old Chinese Mining and Technology University (Beijing), came.

"I'll buy cups first, let's talk while drinking." Zhang Jincang proposed. The sky was getting late, and Zhang Jintong slowly opened the box next to the small round table.

Choose scientific research work and fit the development needs of the industry

Zhang Jinwang is from Shanxi. Growing up in Shanxi, a large coal province, Zhang Jincang has learned more about the coal industry since he was a child. Considering the wide employment of engineering, in 2008, Zhang Jincang was admitted to Chongqing University and chose mining major.

At the undergraduate stage, Zhang Jincang often went to mining to study. "At that time, we went to a mine in Chongqing Energy Investment Group. The coal seam of that mine was relatively thin, the inclination angle was relatively large, and the gas content was relatively high. I ca n’t stand up straight, I feel very hard, making me feel deeply. ”Zhang Jincang recalled.

In the senior year, large coal groups went to the campus to give preaching. Among them, the supplementary tower coal mine with an annual output of over 10 million tons caused Zhang Jincang's attention. Different from the southern thin coal seams, this mining coal seam of the "world's first well -known industrial and mining" at that time was thick and geological conditions. The changes in its scientific and technological development to the working surface impressed Zhang Jintang.

Employment or study? Combined with the internship experience and insight, Zhang Jincang gradually made his own judgment: "The coal mines in the east and south may be deeper and deeper, the conditions are becoming more and more complicated. Getting higher and higher. Therefore, in the long run, it should meet the needs of the industry, learn more knowledge and do more scientific research, which should help future development. "

Professor Wang Jiachen is with Zhang Jinwang

In 2012, Zhang Jintang came to China University of Mining and Technology (Beijing) to study. Professor Wang Jiachen, a well -known expert in the field of coal mining, continued to study mining engineering.

"Our major has the saying of" wide -caliber and thick foundation ". In addition to basic theory, the professional background color is actually more focused on engineering technology." Zhang Jintang said. Combined with the rules of the migration of coal seams specified by the tutor, Zhang Jintang began to contact some scientific research projects. Through constant assumptions and verification, analysis and summary, he gradually explored the methods of doing scientific research.

Inventory of one book, a sense of harvest achievement and meaning

"How to optimize the process and improve the recovery rate of the use of top coal mining?" On the basis of the relevant knowledge accumulation of the undergraduate stage, during the period of studying for a master's and doctoral degree, Zhang Jincang did some test research and theoretical analysis in the pink coal mining process. In 2018, he and his mentor Wang Jiachen and brother Wang Zhao co -authored the book "Basic theory and Application of Putting the Basic Coal Molying", published by Science Press. The book details the basic theory of crushing and release of top coal, and proposes a variety of process methods to improve the recovery rate of top coal.

In 2020, by chance, Zhang Jintang chatted with a coal -to -coal -release technology worker on the front line of coal mine production. He learned that the other party had bought this book to study and applied the optimization method of the coal release process to the live production. The workers showed Zhang Jinwang some application scenarios, and said that because the book was introduced in more detail, they followed the steps to make practical applications step by step to improve the recovery rate.

"I was very happy when I heard him say this at that time. At the earliest in 2015, we conceived some new crafts. After brewing for a long time, I finally wrote it. , Very fulfilling, "Zhang Jincang said.

The process technology has been recognized by the production of front -line workers, which not only verifies the rationality of theory, but also stimulates the enthusiasm of Zhang Jintang to participate in scientific research.

Comprehensive release of top coal will cause losses, especially the losses of coal on top of the working surface. Reducing the amount of top coal in the process of putting as much as possible has always been an important technical problem facing the field of comprehensive mining. During the blog, the instructor Wang Jiachen proposed a subject to Zhang Jinwang -how to improve the recovery rate of the top coal of the comprehensive work surface. In order to find the answer, Zhang Jintang pondered how to optimize the traditional craftsmanship, and went to theoretical analysis after the idea.

"Once an analysis, I suddenly thought that according to the traditional process, if coal was placed from point B from point A, there were more losses at the top coal at point B; otherwise, there were more losses at point A. Can you be able to? Combining the two directions? We first set up counter -segments at the approach of point B, starting with point B from point A, when reaching the inverse section position, we will put coal from point B to point A, which is equivalent to The lower end can recover a part of the top coal to reduce the amount of coal loss. "Zhang Jinwang explained to the reporter while drawing.

This innovative method is called the end of the end. After putting forward ideas, the theory is required in the laboratory. During the research, Zhang Jincang also summarized experience: "Any method that can be solved from the process is the lowest for the company. If it cannot be solved from the process, the equipment must be transformed, and the cost will be relatively high."

In February of this year, "a coal -to -coal release system and method that reduced the loss of coal on the top of the comprehensive work surface" was awarded the national invention patent. The invention patent has been rated as "optimizing the traditional coal release process and can effectively reduce the loss of top -opening coal." Nowadays, the coal -to -coal process of the end of the end has been promoted and applied in many coal mines, and has achieved good economic benefits. "In scientific research, the most important thing is the proposal of innovation ideas. But the idea can not be arisen at once, and it needs to be continuously accumulated in the early stage to perform numerical calculations and theoretical analysis. With these pavement, and then in -depth thinking, you will before you think about it. Thinking about it, can I try it like this or so. "Zhang Jincang said," Although there are more and less successful attempts, we still have to continue thinking, simulation, analysis, and verification until we can persuade ourselves. "

Inheritance knowledge and exploration spirit, and protect students' enthusiasm

During the post -doctoral period, Zhang Jincang began to undertake some lectures. Today, Zhang Jinwang has become an associate professor, lectured on the introduction of energy development, professional foreign language and other courses. In terms of talent training, he also has his own thinking.

In 2020, some undergraduates found Zhang Jinwang, saying that they wanted to sign up for the practice of the professional work of the mining engineering students. Zhang Jincang was asked to serve as a instructor. Zhang Jincang is very supportive and said that he can communicate and discuss at any time. The content of students is about how to effectively identify coal and vermiculite in the process of intelligent comprehensive mining. Among the six students, there were two schemes, but the competition could only submit one work. The stalemate is not undergoing, and the students propose to make the model into two layers, using different solutions.

Can you do it? Zhang Jincang's heart was drumming. But considering the enthusiasm of students, he felt that he could try it. After the students worked overtime and finished the model, they were denied in the first round of reviews in the school.

"Some students came to me at the time, and I was in a very low mood. But since everyone has already made it, I should encourage students to continue the competition. So I tell them, no matter what the teachers say, your work is here for me It is recognized. According to the suggestions and opinions, the amendment and the competition will participate. "Zhang Jincang said.

None of them did not expect that the work of "comprehensive mining of coal -to -coal dynamic identification physical models" has won the first prize of the 10th National College Mining Engineering Student Student Student Student Student Practice Contest, and it is the only first prize in the school that year. "The students were particularly happy. Fortunately, they persisted at the time. This was a great inspiration for them. When we were teachers, we must protect the students' interest and exploration spirit." Zhang Jintang said.

This incident made him feel very pleased: "Maybe your words can affect students for a long time. When I first came to the mine, I didn't understand anything. It was my mentor who took me to contact scientific research. Interest. In retrospect, there can be a little achievement now, inseparable from the guidance of the mentor and the support of the team. "

Zhang Jinchangwang made a special report at the 2021 Science Mining Forum

After being selected as the young talent support project of the Chinese Association for Science and Technology, Zhang Jincang thought a lot. "What is the support? It is you to climb to a higher place. You can't go up by yourself, you need to help you. Like my mentor, Professor Wang Jiachen, other seniors, regardless of academic help, no matter what academic help, no matter what academic help, no matter what academic help, no matter what academic help, Still the guidance of scientific research is a lifting. The state uses policy means and incentive methods to help you, and supports you to do more innovation and breakthroughs. "

In Zhang Jinwang's eyes, he is more "satisfactory" and does his own business silently, and the output of scientific research and teaching results, like the light from the stars in the night sky, always can be seen after a long time. Overclocking and accumulating hair is his attitude towards scientific research.

"Academician Qian Gaoming in our school is almost 90 years old, but the masonry beam theory model proposed in the 1970s still affects the industry and can produce huge benefits." Zhang Jintang said, "So, graduated Later, I did not choose a company, but chose to stay in the school. On the one hand, I wanted to have some impact on the industry through scientific research. On the other hand, through contact with students, to develop the spirit of the inheritance of the mine and affect more people. "

For Zhang Jincang, China University of Mining (Beijing), which has been spent 10 years, is his own home. Today, the school has opened new majors such as smart mining engineering, new energy science and engineering, and Zhang Jincang is preparing new content for the new course.

"Scientific research is to try to expand the boundaries of knowledge a little bit. I just need to push forward a little bit, correct or wrong, they are accumulating knowledge. But as long as it is done, the significance may be more than that." Zhang Jincang said.
