During this period, the “Beijing-type Rotary Core Drill” series was designed and led to enable the metallurgical geological system to fully update the drilling equipment. This project won the second prize of new products issued by the State Economic Commission in 1964.

2. Participate in research work on superhard materials and products

In order to improve the level of drilling technology in China, since the 1970s, we have participated in and led the transition from metallurgical geological drilling to "small-diameter synthetic diamond drilling technology" and organized the development of various hydraulic drilling rigs. Among them, he has presided over the successful development of the "Diamond-200" full hydraulic pit drilling machine, which has been fully promoted in the mine pit; the small-diameter synthetic diamond drilling technology involved in the development and assistance of the leadership has replaced the crude and backward alloy and steel drilling technology. He won the first prize of National Science and Technology Progress Award; he also presided over the successful development of three types of synthetic diamond presses, among which the "HS610000kN press", which was developed in the early 1990s, was awarded at the 8th National Invention Exhibition. Gold and Liaoning Province invented the first prize and won two national patents; actively supported the raw materials of the coarse-grain high-strength synthetic diamond single crystal, polycrystalline, composite sheet, cubic boron nitride and other superhard materials carried out by the team led by Fang Xiaohu. , research, purification, testing and other aspects of scientific research and the development and production of diamond drill bits, won a number of major breakthroughs; the "NCO-1 core orientation device" hosted by the institute won the second prize of the ministerial level and obtained the national patent .

With profound technical ability and outstanding performance, he has become the academic leader in the research field of exploration technology of Guilin Institute of Mineral Geology. He was the director of the Research Institute of Exploration Technology. Enjoy the special allowance of the State Council and the vice chairman of the Second Exploration Committee of the Chinese Geological Society.

In 1985, he obtained the qualification of master's tutor. By 1989, he had three master's degree students together with the Department of Geology of Central South University of Technology, and both obtained master's degrees.

3. The achievements achieved during the leadership of the Exploration Technology Research Laboratory play an important role in promoting the development of the superhard materials industry.

1) Since the 1970s, the research work of leading exploration rooms has turned to the research of new drilling technologies with synthetic diamond drilling technology as the core.

According to the needs of the project, the research expands in depth, including: research and development of drilling technology with synthetic diamond drill bits as the core, and development of other diamond products; research on pipes, drills and related equipments with synthetic diamond drilling rigs; The main strength of synthetic diamond, including cubic boron nitride and other superhard materials and their manufacturing processes, equipment, raw materials research. For more than 30 years, he led the exploration room science and technology personnel to carry out research work on new technologies and related technologies around synthetic diamond drilling, and completed nearly 100 topics. Among them, there are 54 national and provincial-level projects, and dozens of in-house and horizontal contract projects. For more than 30 years, it has won 2 national scientific conference awards, 1 national first prize for scientific and technological progress, 1 national invention fourth prize, and 51 provincial and ministerial scientific and technological progress awards, including 9 second prizes.

2) Make important contributions to the promotion of synthetic diamond drilling technology in China

A series of research results of the Exploration Technology Room made the synthetic diamond drilling technology quickly support and fully promoted and applied in China, completely replacing the “steel grain” drilling technology introduced from the Soviet Union in the 1950s, and realized the “small caliber” drilling of synthetic diamond. technology. The drilling efficiency has doubled, and the monthly efficiency (monthly footage) has doubled, from more than 300 meters per month to more than 600 meters per month, even up to a kilometer, and the realization of the "steel grain" drilling can not be constructed. The ultra-thick deep hole drilling and horizontal drilling in the pit. Drilling equipment and drilling tools have been lightened, and the mechanization of operation has been greatly improved. In particular, the promotion and application of drilling and core drilling technology has not been mentioned, which has further reduced the labor intensity of workers and completely changed the backward appearance of drilling technology in China. Saving hundreds of millions of drilling costs (eighties) for the country has greatly accelerated the speed of geological exploration and modernized drilling technology.

On July 5, 1975, Xinhua News Agency issued the "Dynamic Diamond Drilling Technology No. 1819" domestically developed with the advanced "synthetic diamond drilling technology" in China. The article pointed out: "The Exploration Technology Research Laboratory of Guilin Institute of Metallurgical Geology is With the close cooperation and strong support of all relevant units in the country, it took only 5 years to research and successfully develop the artificial diamond drilling technology that has reached the world advanced level, and began to promote its application.” This article has received the attention of the central leading comrades. Comrade Li Xiannian, then vice premier of the State Council, instructed: "Baohua comrades read, investigate, if true, should promote and strengthen the team, open on-site meetings when necessary, and draw strong measures to promote it." On May 29, 1977, the People’s Daily made an official report on the “Successful Research and Testing of New Synthetic Diamond Drilling Techniques”; in 1978, the “Math Diamond Drilling Technology” project of the room won the National Science Conference Award. In 1985, “Promotion and Application of Diamond Geological Core Drilling Supporting Technology” won the first prize of National Science and Technology Progress Award, and I obtained the certificate.

3) Participate in and lead the design of the six-faced diamond press, and make greater contributions to the independent development of the six-face press in China.

Under the auspices of the Ministry of Metallurgy in 1971, he led the research team to assist the Ministry of Metallurgy in the first two 6×600T six-sided diamond presses in the Shougang Exploration Team and the Mineyard. Subsequently, the Ministry of Metallurgy quickly armed the exploration company machinery factories in various regions, and the relevant domestic departments later also put on diamond presses. The huge “compressor group” not only contributed greatly to the smooth promotion of China's synthetic diamond drilling technology, but also accelerated the rapid development of the superhard material industry. In 1985, the company designed and developed the CS-1 type 6×800T press headed by Shen Rongyuan, and successfully transferred the technology to the Guilin Metallurgical Machinery Factory for mass production, which became the main product of the plant. The technicians of the plant continued to develop and expand the variety. The specifications make it the largest press production base in China with an annual output value of several hundred million yuan. The project won the second prize of 1989 Nonferrous Metals Corporation Science and Technology Progress Award and the third prize of Guangxi Science and Technology Progress Award. Between 1993 and 1996, after retiring, he successfully tested HS6×1000T and UDS-I6×1300T presses in Shenyang and Henan, and obtained two national patents.

4) Make outstanding contributions to the independent research and development of diamond drilling rigs

The design of the drilling rig is the strength of the exploration technology room. In the 1970s, the diamond-300 full hydraulic drilling rig with advanced performance was first introduced in China, and the development of the diamond-100, diamond-200 and diamond-600 series hydraulic drilling rigs was completed. At that time, it caused a sensation in the industry peers. In 1978, he received the design and development of the "August 1" full hydraulic remote control drilling rig for the underground nuclear test sampling issued by the National Defense Science and Technology Commission. In the same year, the former Academy of Sciences Dean Lu Yongxiang participated in the design of the hydraulic system of the drilling rig. After the rig was assembled and tested in Guilin, It was transported to the nuclear base of Lop Nur, Xinjiang by special plane. The research laboratory comrade took the newly developed "August 1" full hydraulic remote control drilling rig, rope core drilling tool, aluminum alloy drill pipe and diamond drill bit to participate in the timely rapid drilling after the underground nuclear explosion. The arduous work of sampling. They ignored the danger, were not afraid of fatigue, worked hard in succession, successfully completed the task, and received the award from the base.

4. Developed a group of academic leaders and technical backbones for the industry

For the successor of China's exploration technology talents, the younger generation of technicians have been carefully trained and passed on for many years. The exploration technology room has emerged a group of influential academic leaders and technical backbones. Such as Li Zhenqian, Lu Zhi, Mo Shixiong, Fang Xiaohu, Zhang Yizhi, Qu Yazeng, Zheng Chao, Yao Liyin and Lin Mingxi. These comrades have made outstanding achievements in different periods and in different positions, and won many awards. However, as a leader, I have no name in the list of the research team, so that I have no chance to win the award. In fact, in the course of many research projects, I have devoted a lot of my efforts, but I have no regrets. Their success is my success, their glory is my glory. I am worthy of my time, and I am worthy of my beloved career, and even more worthy of my motherland. (Excerpted from "Fifty Years of China's Superhard Materials Industry")
