Fifteen years ago, a major gas explosion occurred in a coal mine, killing 35 people on the spot, seriously injuring 17 others, and leaving 10 people missing, one of the worst disasters of the year. After the accident, the city immediately organized emergency rescue, fire and hospital mobilization, and after the citizens got the news, they also organized blood donations, and the scene was very touching for a while. But unfortunately, only two of the ten missing people were finally recovered, and the remaining eight were all dead when they were found a few days later. The impact of this accident was very bad, and the local coal mines were all shut down, and the people were very worried about it, because of the serious accident and the heavy casualties, the incident alarmed the province, and the above ordered a thorough investigation.

The local safety supervision department cooperated with the police to conduct an in-depth and detailed investigation, and after several months of arduous investigation, it was finally determined that this was a major safety production liability accident. The former mine manager was dismissed on the spot for his leadership responsibilities, the deputy mine manager in charge of safety was sentenced to prison for the main responsibility, and several people involved were also implicated. Subsequently, the miners who died in the explosion received huge compensation, and the city did its best to the injured miners and all the victims' families, and it took about half a year for the matter to be revealed, and the coal mine was shut down for more than half a year.

After the dust settled, the coal mine resumed production, but because of the impact of the previous major accident, basically no one was willing to take over the mess, and few miners were willing to take risks on the mine that had exploded, and they all turned to other places.

At this critical juncture, Mei Yuanzheng, the second deputy mine manager of the original coal mine, who was resolute and upright, was promoted to the post of mine manager, and Gao Kehua, an honest and steady senior technical talent, was promoted to the second deputy mine manager. After they took over, they immediately devoted themselves to their work, paid attention to safety, and also inspected the mine many times to ensure that all the hidden dangers underground were eliminated before announcing the results. Thanks to the efforts of Mei Yuanzheng and Gao Kehua, the coal mine was able to get back on track little by little, although the scale of production was still small at the beginning, but it was finally carried out normally.

Mei Yuanzheng and Gao Kehua had been working in the mine and were very familiar with the situation in the coal mine, and under their guidance, the situation had greatly improved. However, due to the heavy losses in the last accident, many experienced miners died and were injured, resulting in limited production capacity, which also restricted the further development of coal mines.

Soon after, Xue Kui, Zou Qi and others returned from their studies, and under the coordination of Mei Yuanzheng, they were all recruited into the mining area and became excellent management and technical talents in the coal mine. At that time, Xue Kui was still very young and ambitious, and he also devoted himself to production and managed in a modern way, while Zou Qi took the lead and entered the underground many times, personally guiding the newly recruited miners to detect data and embankment hazards, and also organized safety production training many times. At this point, the coal mine began to develop rapidly, which can be described as thriving and regaining vitality. After nearly a decade of joint efforts, even if there have been a few minor accidents before, it is not harmful, and before this year's gas explosion, the amount of coal mining had already exceeded that of the peak of the year. It's just that I never expected that under Beiting's investigation, I found out that Xue Kui instructed Wang Mazi to do many criminal deeds, using the country's resources to create economic benefits for himself, which eventually led to today's results.

Li Yiting's trip can be described as a huge gain, he determined that what Zou Shaotang said was true, before Xue Kui and others came here, there was a major gas explosion case, and it was particularly serious, it was actually this coal mine. And Zou Shaotang actually saw a grimace butterfly after that catastrophic mining disaster, you know, the butterfly was artificially put in, so Li Yiting definitely has reason to suspect that the major mining disaster and a series of explosions made by Wang Mazi are also man-made!

Chen Tianyu appeared in front of Xu Jie with Xu Jingnan, and his reaction was the same as Qin Wu of the Safety Supervision Bureau, which was very unexpected. Xu Jie was a little confused and asked, "Chief Inspector, are you back again?"

Chen Tianyu took the initiative to explain, "Captain Xu, we didn't leave, and there is no problem of coming back, but this time, I want your help because of something." Fifteen years ago, there was a serious explosion in the mine, did you know about it?"

Xu Jie shook his head in confusion, "I was only transferred here eight years ago, and I don't know what happened more than ten years ago." ”

"That's okay, we want to ask you to help us get the file of this case from fifteen years ago. I know it's not very easy to do, after all, it's been so long, and it's all old, but it may have a lot of effect on the current coal mine explosion case. Chen Tianyu pleaded.

"You mean Xue Kui and the others committed the case? But didn't they come to the mining area ten years ago? How could it be related to the case from fifteen years ago?" asked Xu Jie puzzled.

"That's right, it's because they've only been here for ten years, but we learned that after that explosion fifteen years ago, there were also grimace butterflies, just like they are now, and we hope that Captain Xu can find a way to help. Chen Tianyu's attitude is unwavering.

In other words, the cause of the explosion may be the same as this year's, but the culprits cannot be Xue Kui and his gang. Xu Jie frowned.

Chen Tianyu nodded, "What Captain Xu said is right, because of this, we have to go through the files of the year, and maybe we can find clues." ”

Xu Jie agreed, "Okay, Chief Inspector, I'll arrange this matter, but you need to go through the normal procedures." With that, Xu Jie took them to the archives to retrieve the files of the coal mine gas explosion case fifteen years ago.

Fortunately, there is a signboard of the Beiting Detective Agency, and the police are very cooperative, and the procedures are completed quickly. The old files from fifteen years ago had long been locked under the cabinet, and everyone rummaged for a long time before they all reappeared in the light of day, Chen Tianyu and Xu Jingnan opened all the files, including the human and physical evidence at that time. The thick stack of case files shows the seriousness of this case, and also proves that the police spent a lot of energy investigating this case 15 years ago, and there should be no mistakes. However, after their efforts to inspect, they did not find any problems from the file, especially for the investigation of the coal mine afterwards, the geological characteristics, gas data, etc. were recorded in detail and were all within the normal range.
