Recently, Shennan Industry Development Co., Ltd., a coal group, has set off a wave of technical attacks. In order to break through technical bottlenecks and enhance core competitiveness, the company's motor and electrical equipment maintenance center has established a number of technical research teams, with the head of the center Rong Minsheng, the general engineer of the center, and has promoted five major projects, including three-stations and CNC SMD bed selection and layout. On February 11, at the 2025 Work Conference of the Coal Group, Rong Min said confidently: "This year, we will accelerate the pace of transformation and upgrading, promote the advancement from traditional maintenance to processing and production, and strive to be at the forefront of the industry."
Rong Min is a technical leader in the coal industry in our province. He broke through the domestic industry's 50 technical bottlenecks and was rated as "national technical expert", "chief technician of Yangxi Province", "sanqin craftsman", etc.
The mechanical and electrical equipment maintenance center of Shennan Industrial Development Co., Ltd. of Coal Group Shennan Industry Development Co., Ltd. is recognized as the "emergency hospital" of large-scale mining equipment, and undertakes the important task of repairing equipment of 11 large-scale mines in the Yanbei area of the Yanmei Group. Rong Min just entered this position and showed the quality of attendance and good learning. He conducted in-depth research on circuit diagrams and recorded the coal machine drawings as soon as each repair task was over. During his 10 years, he was tired of more than 10 thick repair notes.
By using the power of the art, Feng Jing has mastered the hard technical foundation. During the imported equipment technical service process, he solved the problems that equipment production enterprise engineers cannot solve on many occasions, and organized and wrote 291 quality control standards for 18 types of excavated equipment. These standardized formulations not only improve the maintenance level of major technical equipment such as coal-producing machines in our country, but also win international vocabulary rights for the country in this area.
In recent years, with the improvement of the intelligent construction level of the Coal Group, production equipment has been continuously upgraded, and the maintenance work has faced new challenges. Rong Min knows that in order to complete the maintenance task efficiently, you must have an in-depth understanding of the structure and functions of the equipment. He secretly decided: "You must understand the principle map of the mature equipment, so that the principle map can be "going" into the scene and become a "living map" for finding equipment failures."
In order to master the working principle of the equipment as quickly as possible, Rong Min took his colleagues to the factory for study many times. In addition, he will take 10 days a month to go down the well to find out the equipment situation. When the manufacturer staff entered the factory, he seized the opportunity to ask for advice and carefully studied every problem. Through a review of the large number of 2,000 faults in the excavator space in the past 10 years, he compiled the "Three-step Manual for Quick Response of Rongmin Coal Machine Faults". This manual not only improves the team's efficiency in handling failures, but also provides precious experience for cultivating newcomers.
Rongmin attaches great importance to talent training and continuously improves the skills of employees by establishing fault databases and developing small lectures. With his efforts, in the past three years, the company has trained 1 "national technical expert" and 4 "Yinxi Province Technical Expert", 1 person won the "Yinxi Province May 1st Sports Award", and 9 people entered national and provincial levels, etc. The top three in all skills competitions.
Is there a way to obtain first-hand information on coal-fired machine failures more conveniently and quickly, so that repair personnel can perform repairs effectively in a timely manner? In 2023, when asked about this question, the Rongmin Skills Master Studio quickly established a project attack team. The group uses coal-treatment machines to transfer data to the end station and enters the automatic network. It uses the existing automation system to extract data from the district monitoring station, and then conducts visual analysis of the data based on VNC tools. Through the virtual network control platform, the corresponding area is realized. Far control of the team's online monitoring station.
In the past three years, Rong Min has led a member of his Skills Teacher Studio to apply for 30 patents, completed 300 innovative projects, and solved 200 technical difficulties. These innovative achievements not only improve the technical level of our coal industry, but also create huge economic and social benefits for enterprises.
