When going down the mine, it stands to reason that the work clothes, safety shoes, helmets and lamps that do not produce static electricity should be replaced, and the relevant safety guidelines should be observed.

The management system of [Xinsheng Coal Mine] does not pay attention to safety standards, and sooner or later there will be accidents, or sooner or later, there will be accidents, anyway, people will die for several years in a row...

Jiang Feng was not afraid, so he went in and took a look, and he would come back as soon as he finished walking around the main lane; the alley of several hundred meters could pass through small rail coal trucks, and it looked relatively spacious.

"It's boring! so that's it~"

After entering more than 100 meters, there was no change, the black coal dust was everywhere, the blower was "whirring", Jiang Feng didn't have any curiosity, he felt that it was just like that.

When I was a child, I heard my father say that it was hard to dig coal in the coal mine, and I had to bend over and dig on my stomach, and every time I shoveled after the cannon was blown up, but now it's different...

Mechanized coal mining uses coal cutters! There are several fully automatic/semi-automatic/semi-mechanical coal mining platforms in the bifurcated roadway, all of which do not need to be dug by hand.

"Yes, yes, it's still quite advanced, if the management system is stricter, it will be even better!" Jiang Feng and Wei Dawei Er walked in the middle, hinting to the mine leaders.

Wang Bingqing smiled embarrassedly and said: "Actually, we also want to strictly manage, but this is the case in China, the whole coal mining industry is so virtuous, and safety is not taken seriously!"

Don't look at the official every day to pay attention to safety, all kinds of safety supervision equipment are also available, but the attitude of the coal mine is lazy.

Why? If the quality of the employees is not high, the coal miners will not be timid, and their vigilance will have long been paralyzed!

China's coal mine safety supervision equipment is very advanced.

The gas early warning province is networked, and the official can remotely monitor the gas content/blower/video surveillance, but there are still frequent problems, and the management can only be lax.

Jiang Feng was right to think about it, sighed, and continued to walk with the coal mine manager, wanting to see the shearer; Wei Da Wei Er was highly vigilant and looked around to observe the coal mine roadway.

Suddenly, Wei Da took out his camera, took pictures above the roadway, and seriously stopped Jiang Feng: "Boss, you can't continue to go forward, this coal mine is in danger!"

"......" Jiang Feng looked at him in surprise.

Wang Bingqing/Deputy General Manager/Chief of Safety Technology all looked at Wei Da curiously and asked, "Chief Engineer Wei, what danger can we have in our coal mine, the gas exceeds the standard?"

Wei Er: "No, the coal mine is about to collapse." ”

This guy was even more stunned, replied lightly, and then pulled Jiang Feng to prepare to go back: "Boss, the rock above has cracked! Let's get out of here first~"

Wei Da also nodded in confirmation, took out his camera, and showed the [three-dimensional photo] he had just taken, this detector can detect a two-meter depth through perspective, and a 3D three-dimensional map with a green background.

Sure enough, there were several long chasms!

The short-term collapse is not great, and the danger is not great, so the system glasses do not warn, but over time, these cracks will definitely become more and more serious, and it is likely to collapse seriously.

Deputy General Manager: "......" [surprised]

Logistics Chief: "......" [confused]

Security Technology Chief: "......" [frightened]

They also looked at the photos, which were the kind of high-definition images of geological detection, and there were indeed long cracks.

Jiang Feng also looked at it, observed it with his glasses, and found that the problem was really serious!

The length of 500m+/depth of 5m+/several fractures also show a cross distribution, the internal stress is very large, and with the mining vibration and artillery, it will collapse absolutely within a year.

The chief of the safety technology section was frightened, if there was such a safety and quality accident, he would be the first to be held accountable! He hurriedly asked Wei Da expert: "Do you want to evacuate the miners first?"

"That's not necessary, let's send someone to check first~"

Hearing Wei Da's answer, they were not in a hurry, they breathed a sigh of relief and hurried back to the surface, and the deputy general manager arranged for technicians to go down the well and investigate the top of the roadway.

"Yes, yes, yes, just check the top, remember, you must check carefully and carefully! Whoever dares to do something perfunctory, all the fucking rolls and cover and get out, quickly, go down the well immediately..."

Soon, a team of technicians went down the mine, and the deputy general manager pulled Jiang Feng and asked: "Mr. Jiang, this time it's a big trouble, do you have a way to remedy it?"

"Let's see the results of the inspection!" Jiang Feng shook his head helplessly and replied perfunctorily, the top support is not realistic, this time the crack is too long and deep, I'm afraid I can't withstand it at all~

Several leaders of the coal mine were so anxious that they immediately reported to the company's senior management for instructions, asking what to do?

If something really happens, I can't imagine it...

I also admired [Lingfeng Technology] even more, and almost knelt down for Wei Da Wei Er, the technical boss, definitely the top technical boss, and there was a faint admiration in my heart.

After a while, the results of the examination came in---

Huge collapse hazard, wide area!

At the same time, the head office sent a message that the coal mine should immediately stop coal mining, and block the tunnel, and ask a professional geological inspection company to evaluate and study solutions.

", I don't have a backache when I stand and talk, who should I ask to study the solution?" the deputy general manager scolded, he is fully responsible for the coal mine, and now it is really hot~

The roadway covered by the hidden danger is 300 meters!

"Paralysis, this can't stand at all!" The height of the roadway makes it difficult to hold up, and the stone is too heavy to hold even the iron plate, and the technology is obviously not up to it.

[Xinsheng Coal Mine] mourned all over the field, and a large number of leaders were all like mourners, arranged for workers to evacuate, temporarily stopped work for a period of time, and then studied and repaired the main lane.

Anyway, it didn't help much, Jiang Feng was ready to say goodbye and leave to go home, Luo Hontian was bored, and he kept urging him to go back to sleep, and he got up too early in the morning...

The shed of his own factory is busy renovating, and Jiang Feng also plans to go back early to help, to see if Gong Dagong Er has repaired the roof in the morning. Suddenly, his eyes lit up---

"Perhaps, I... There can be a way to solve it!"

Wang Bingqing was overjoyed: "Mr. Jiang is serious?"

The others were also full of surprise, and the deputy general manager pulled Jiang Feng and begged: "Mr. Jiang, help, brother, I really have no other way, I can only rely on you!"

"I'm not sure, it's just possible..."

Jiang Feng just suddenly thought: Aren't the engineering troops specialized in engineering? Perhaps, maybe they can solve the problem of the hidden danger of rock collapse in coal mines?

Wei Da knew what the boss thought, nodded solemnly and replied affirmatively: "No problem, it's trivial, but the cost should not be low, this is very technical." ”

Jiang Feng gave him a thumbs up in his heart, this guy is getting better and better at [God Assist]! As soon as he opened his mouth, he brought out the problem of expenses, and he didn't need to talk about it himself.

"Hmm~yes~It's just that the engineering team has other important work recently, and it may take a few days to wait, and then we can negotiate the price, okay?" Jiang Feng asked them.

The deputy general manager hurriedly smiled bitterly: "Can Mr. Jiang try to arrange an early meal? The price is not a problem, I have absolutely nothing to say about your offer! The coal mine can't last too long..."

"Rest assured, four or five days at most. ”
