In this year's college entrance examination, Xu Zhang Leyan, the daughter of Xue Liang, the captain of the ventilation team of China Coal Sanjian Chaoyuan Coal Mine, was admitted to Tsinghua University with an excellent score of 698 points. When the good news reached the mine, the surrounding leaders and colleagues felt that this was expected. Because of "going out of Mulan", they have seen the performance of the "Xue Team" in their work over the years, so serious and meticulous, with clear thinking, and often forgetting to sleep and eat for technical problems that they can't figure out. Employees all guessed: Could this scarce excellent quality on his body be some mysterious "Tsinghua gene"?
In the past 32 years of work, Xue Liang has walked through plains, wildernesses, deserts, tunnels, shafts, and mining faces, quietly sweating, silently dedicating wisdom, and always sticking to the front line of "one pass and three defenses" in the mine.
Study hard and practice strong skills
Xue Liang grew up in the countryside since he was a child, and with the idea of "learning the craft to support his family", he chose the ventilation major. In 1992, Xue Liang entered the 30th Engineering Department of China Coal Third Construction Group, at that time, he did not understand ventilation technology, and he felt very difficult to do anything.
Xue Liang was not discouraged, he seized all the time, read a lot of various ventilation professional books, self-taught relevant knowledge, and constantly strengthened theoretical learning. According to the guidance of the master, as soon as he arrived at the post every day, he asked the teacher to learn the technique. At work, Xue Liang does not miss any opportunity to learn, as long as he encounters work problems, he always asks the roots, finds out the reasons behind them, and gives reasonable solutions. After a period of accumulation, Xue Liang has grown from a general worker to a skilled worker.
Since 1993, Xue Liang has been responsible for gas measurement in important areas of the mining area. He seized every opportunity to practice and exercise his measurement ability, making himself a "gas measurement master" in the area where gas gushed out of the anomaly.
"At the construction site, where the area is abnormal in gas gushing and the measurement technology is high, the captain will assign Xue Liang to go because of his accurate measurement. In addition, it can also make advanced and accurate predictions by gushing out of the surrounding gas. Xue Liang's co-worker said.
At that time, Xue Liang's arms and legs had scars left by work. Xue Liang said with a smile that his "unique skills" were "drilled" little by little.
"There are some special areas that require an arm and head to poke over, on the one hand, the measurement is accurate, and the surrounding coal seam structure can also be observed. Gangue abrasions are also unavoidable. Then, he is the 'most beautiful boy' in our gas measurement team. Xue Liang's "old partner" Zhang Xiang said. Everyone admires Xue Liang's "fine god", and it is with such a spirit of not being afraid of hardships and difficulties that his skills are becoming more and more exquisite.
Over the years, Xue Liang has participated in the construction of more than 30 projects in Henan, Shanxi, Shaanxi, etc., it can be said that the length of time, the depth of hard work, increased the thickness of skills, he has won gold and silver in the skills competition of the group company many times.
Overcome difficulties and take responsibility
Over the years, Xue Liang has been innovation-oriented, meticulous and quality-oriented, overcoming difficulties and solving complex problems in management.
Xue Liang is not tall, with a humble smile on her broad cheeks, and she always seems to be thinking about something when she walks. Xue Liang doesn't greet others very much, it's not that he is cold and rejects people thousands of miles away, but that he is thinking about things at work, which is a habit he has developed over the years. From an ignorant young man who didn't know anything, he grew step by step into a skilled management talent, and only he knew the hard work and efforts he made during this period. Xue Liangshe's small family, taking care of everyone, devoted himself to the safety production of the mine, and made great contributions to the ventilation safety of the mine.
"I would like to thank my family, especially my wife and children, without their understanding and support, I would not have been able to achieve these achievements." Xue Liang often said this. But it is in this cycle that Xue Liang's attitude towards work has always remained the same. "One day on the job, one day safe."
Mine ventilation management must not be sloppy, we must always be in good spirit, scientific measurement and analysis of all kinds of data, so as to prevent problems before they occur! Similar to such a mantra, the cadres and workers in the ventilation area remember that the melon is ripe. Nagging is nagging, but when it comes to specific work, Xue Liang is not sloppy at all. In mid-October 2023, Xue Liang was leading the shift underground, and due to the soft coal quality in the new mining area, there were frequent roof leaks during the tunneling process. Xue Liang clearly knows that the ignition period of spontaneous combustion is only 30 days. Coincidentally, the dispatcher on the previous shift reported that there was a roof leak of about 0.8 meters in the 31102 tunneling, and there was a hidden danger of spontaneous combustion of the coal seam. Without hesitation, Xue Liang included the excavation face that did not belong to the inspection line into its own inspection scope
"Captain Xu, the wind surveyor at work has just checked the local temperature, and it is normal here for the time being" Seeing Xue Liang raise the infrared thermal imager in his hand, technician Li Dongdong walked up.
"Where is normal? The temperature shows 26.5 degrees, fortunately, the carbon monoxide concentration is not high, you hurry up to notify the team to get under 10 barrels of Ma Lisan, and then call the ventilation team to ask the on-duty personnel to assemble quickly, and immediately leak the top and plug it. We will continue to monitor ,...... here" After doing all the emergency handling work, Xue Liang raised her right hand, which was already slightly numb, and measured. When the personnel and materials were all in place, Xue Liang and everyone blocked the leaky roof, and for 10 hours, he stared at the scene without a moment of relaxation.
When Xue Liang faced urgent, difficult, dangerous and heavy tasks, Xue Liang bravely took on heavy responsibilities, led the team to overcome difficulties, and solved one technical problem after another. Xue Liang arrived at the underground site very early every day and worked until late before leaving. When working, Xue Liang always walks in front of the team, arranging work tasks and explaining the safety protection essentials of the shift while walking.
Rigorous and meticulous to solve problems
Ensure safety with fine management. It is the question that Xue Liang thinks about most often.
"Fine management is all-encompassing. At the daily class meeting, everyone analyzed and predicted the production site, operating environment, personnel behavior, risk identification, accident consequences, job responsibilities and control measures, and realized the good habits of self-insurance, mutual insurance and joint insurance from the action. Xue Liang said. For ventilation personnel, mine safety is a part of their lives.
To grasp the work of "one pass and three defenses", we must have embroidery skills. At one time, the gas sensor of one working face was interrupted. The maintenance crew opened the junction box to reconnect it, ran it for several hours, and the same failure happened again. From the morning shift to the night shift, the same problem occurs continuously. This makes everyone confused, if it cannot be solved in a short time, it will cause gas failure and power outage, and the work face will be shut down, which will affect the safety of production, and the consequences will be unimaginable.
In the deep alleys, Xue Liang and his team search for hidden answers. In this way, for 9 consecutive hours, they carried out all-round maintenance of all lines and instruments, and also competed for speed, and used the strength of the team to fight a "big victory", and a group of people captured one after another "eliminating technical dangers".
Particularly combat-ready teams, they need to be hardened in extreme conditions. After thinking calmly, Xue Liang made a clear response at the mobilization meeting: "If we don't know, we will learn little by little, learn from manufacturers, learn from technicians, and learn from manuals." I don't believe that I can't learn well and can't do it. ”
Today, he and his team members have achieved "one touch" of the circuit components of the monitoring system, "one clear" of the main parameters and technical performance indicators, and "one hand" of finding and eliminating faults. Whenever he encounters a difficulty, he can always come up with a good way to save time and solve the problem.
"Without strict and meticulous truth, there is no first-class ventilation management." Xue Liang regards the ventilation team as a stage for military training, holds small technical competitions and carries out independent innovation activities every month, researches and analyzes various facilities of the underground ventilation system, and broadens the innovative ideas of the members of the innovation studio. He set up three innovation groups for gas measurement, ventilation and dust prevention, and successively led the research and development of innovative achievements such as "Anti-slip Adjustment Wind Window", "Feng Shui Linkage Induction Spray System" and "Coal (Dust) Induction Automatic Sprinkler Device", which can save more than 30 yuan for enterprises every year. The apprentices have won the titles of "Technical Champion" and "Technical Model" of the instrument testing workers of the group company for many times.
Stick to the original intention and pass on the skills
Xue Liang not only strives for perfection in the technology of "one pass and three defenses", but also pays attention to the cultivation of skilled talents. In October 2023, the "Model Worker Innovation Studio" was established in the mine, and Xue Liang began to lead technical and skilled talents to tackle ventilation management problems. Xue Liang said: "As a ventilation craftsman, we must be good at applying our own technology to specific management, and achieve technological breakthroughs in the construction process and explore solutions to problems." ”
After the establishment of the "Model Worker Innovation Studio", he devoted more energy to the training of excellent ventilation technical workers. When training young students, he taught business knowledge in detail, patiently answered questions, and strived to explain each knowledge point and key point clearly.
At the same time, Xue Liang will also conduct on-site training for students based on the actual situation. During a confined wall construction, he found that several employees were adding pulverized coal in the process of mixing sand and gravel. He stopped the construction on the spot and scrapped all the slurry.
"A confined wall is the lifeblood of a mine. If the seepage causes air leakage, it may lead to an accident that destroys the mine and kills people, and the consequences are unimaginable. Xue Liang asked the employees to analyze the knowledge they learned on weekdays and teach the process of wall building by hand. Through continuous practice, employees establish a high-quality construction concept.
Under the guidance of Xue Liang, several ventilators in this mine have grown into top-notch talents of the group. Xue Liang's apprentice Zhang Wei said: "I am lucky to be his apprentice. The master's rigorous, persistent, dedicated and innovative spirit deeply influenced me. I will continue to work hard, master a skill, hone exquisite skills, and strive to read the 'Tsinghua' of ventilation business in an ordinary position." ”
