After 17 years of persistence and unremitting efforts, we have won the "Shaanxi coal cup" 2020 national coal industry professional skills competition, the special prize of safety instrument monitoring. In September this year, the "Shaanxi coal cup" 2020 national coal industry vocational skills competition was held in Shenmu City, Shaanxi Province. After fierce competition, Li Ming, an employee of Renlou mine communication and Prevention Department of Wanbei Coal and power group, won the special prize for safety instrument monitoring.

Li Ming started work in 2003, became a safety instrument monitoring worker six years later, and worked hard in the safety instrument monitoring post for 11 years. In 2018, Li Ming participated in the "Mason" cup national coal industry intelligent safety monitoring competition and won the first place in the intermediate working group. In 2019, he won the first prize in the "Henan energy cup" national coal industry vocational skills competition. Not long ago, he won the special prize in the "Shaanxi coal cup" 2020 national coal industry vocational skills competition. Behind the three consecutive years of honor is Li Ming's pursuit of improving skills.

love whatever job one takes up

As a native son of coal mine, Li Ming is a standard "second generation of coal". In 2009, he just joined the monitoring team. Although he is full of love for coal mines, he has little knowledge of monitoring operation technology and is a "layman". In order to improve himself, Li Ming consulted his predecessors, learned from his fellow workers, and learned from the technical personnel of the manufacturer. He has chewed the "safety instrument monitoring workers", "coal mine safety regulations expert interpretation of underground mining" and other books. "It's only on paper that you'll feel shallow at the end of the day, and you'll have to practice it." So Li Ming applied the theory to his work, and soon mastered the professional skills of safety instrument monitoring, and his ability to find and solve problems was also improved.

One cultivates, one gains. After improving his ability, Li Ming took an active part in the competition. He won the first place in the competition for young workers in the mine and the first place in the group company's youth competition. He became a technical magnate.


Love your business

In his daily work, Li Ming worked conscientiously and carefully to solve problems one by one, and "cured" one set of equipment.

In Renlou mine, a personnel positioning substation in the upper substation of II2 auxiliary mining area under Renlou mine suddenly lost communication, and several maintenance personnel worked hard for two days but failed to repair it. After receiving the task, Li Ming checked the monitoring circuit, thought and analyzed the fault, and found that the problem was that a power board in the substation power box was burnt out. He quickly replaced the switch power board to ensure the normal operation of the signal. The whole process only took 10 minutes. His superb technology was affirmed by the leaders and recognized by colleagues.

In order to improve the quality of the staff, Renlou mine has set up the "one ventilation and three prevention" practical operation base at the auxiliary wellhead, which provides a high-quality platform for the training of safety monitoring workers. Li Ming used this platform to deeply study the business knowledge of "one ventilation and Three Preventions", trained new employees, taught them how to check problems, find hidden dangers and remove faults, and contributed to the construction of mine team.

This is only the tip of the iceberg in Li Ming's daily tedious work. He and team members work together to overcome difficulties, practice the craftsmanship spirit, and contribute wisdom and sweat to the high-quality development of Renlou mine.


One line, one line, one line

The reporter learned that the "Shaanxi coal cup" practical operation requires the contestants to complete the monitoring equipment connection, network configuration, emergency linkage setting, sensor calibration, simulation of linkage process, normal operation of various functions of the test system, GIS icon annotation and many other projects within 70 minutes, which poses greater challenges in the innovation and difficulty of the examination. "It is very difficult to weld the optical fiber of the newly added project in this competition. Each fiber is thinner than the hair, and the operation is required to be stable. As long as the heart is not calm, the hand will shake, resulting in unqualified fusion. "Li Ming said.

In order to practice in mid September and prepare for the war, Li Ming concentrated on the practice and preparation. In view of the theoretical link, he reflects every night on the mistakes in the theoretical link and analyzes the reasons. The next day, he used the mobile app for special consolidation exercises. Making 40 crystal heads a day, the pressing time of a single crystal head is reduced from 7 minutes to 2 minutes and 26 seconds, and the time to complete a drill is reduced from 69 minutes to 52 minutes Second by minute time compression, repeated simulation time and again. Through the "devil" training, Li Ming's hands peeled off one layer after another. At the same time, he insisted on checking the rules and practicing repeatedly every day. From theory to practice, he eliminated the faults again and again and found out the deficiencies. Once, twice, three times Mechanical operation, so that his time to find problems continues to shorten, the ability to deal with faults greatly improved.

Finally, Li Ming achieved high scores in theory and practice in the competition, which was recognized by the professional judges, and won the excellent results of the special award for mine safety instrument monitoring.

"In the face of honor, we have to work harder. In the future work, I will continue to perform my duty well and contribute to mine safety production. " Li Ming has transformed from a "layman" into a "gold blue collar" in mines. He has been awarded the titles of "excellent employee", "advanced individual" and "model worker" by the unit for many times, and composed the praise of mine workers in the new era on his ordinary post.
