According to Gu Yun's visual inspection, the diameter of this air duct should be able to reach 40 centimeters, and the exhaust air volume is very exaggerated, no wonder the boss said that it is no problem to support several mines.

It was only a few moments later that the cavern was filled with the smell of rotten eggs, and it was getting worse and worse.

After smelling this unpleasant smell, the people around did not choose to disperse, but looked at it more curiously.

It took about half an hour to turn on the hair dryer before the smell in the mine faded, and the two people who took over the work picked up the air duct from the ground and walked towards the mine.

They didn't have to wait long, and the two returned, this time saying that the air inside was much better, and it was not as stuffy as it had just been.

After learning of this situation, Gu Jianguo breathed a sigh of relief, and then followed the two of them to carry the air duct inside.

When they had almost laid out the ducts, the technician finally walked in to install them.

At this time, Gu Yun couldn't suppress his curiosity and secretly followed in.

In his previous life, he only knew that there was a coal mine here, and he didn't know what it looked like inside, so after seeing the situation inside, he was still a little surprised.

Gu Yun walked all the way in, and after about 20 meters into the mine, there was a fork, and the mine was divided into two, which should be to increase coal production.

When the air duct arrives here, it is also divided into two, and the joint is a metal joint, and it continues to go deep into it after making a solid docking.

After coming inside, the air duct was not dragged to the ground, but tied to the top of the head by a metal buckle.

I found a mine cave and walked in, this time I walked a long way before I came to the coal mining place, there were still tools left by the workers, and I seemed to be a little flustered when I evacuated, and they were all thrown here casually.

Because of the hair dryer, the methane inside is almost blown away, and the smell already has the feeling of a hint of fresh air outside.

The technician is still doing the final installation and commissioning, and the air outlet is installed in a hidden place, so that the air pressure generated when the air is returned will not be too oppressive inside.

Seeing this technician who was only in his thirties, Gu Yun had the idea of digging the foot of the wall, and he planned to test it later.

There is such a person in the mine, and the machinery and equipment in the future will not be worried, and these people often drink coal to deal with the mine, which can definitely save a lot of trouble for my father.

What satisfied Gu Yun the most was this person's principles of action.

When in danger, he will not go to the scene himself, but he can give reasonable advice.

When it was his turn to work, he didn't shirk his responsibilities at all and started his work silently.

If some technical talent encounters this kind of thing, he must let people go in first to detect whether it is dangerous, and finally he will go in.

And even if you go in and start your work, you won't be as careful as this person.

Gu Yun has seen it just now, and the metal buckle that fixes the air duct will be installed almost every half a meter.

If you encounter an irresponsible, you will only get one every few meters, and some unimportant places will not even be installed, although it seems to be suitable, but accidents mostly occur in places where this kind of detail is not done well.

This is a responsible talent, and Gu Yun's judgment on this person is this.

After a while, no matter how big the chips are, Gu Yun will try to see if he can keep this person.

Two hours later, the exhaust system in the entire mine was installed, and the air ducts were all installed on the top side of the mine, so that people could not move around in it at all.

And every five or six meters, an air outlet will be opened, and after everything is done, except for a trace of glue emanating from the air duct, there is no problem with the air.

And the taste of glue will also disappear after a period of use.

After Gu Jianguo expressed his great satisfaction, the technician took out a signature confirmation form from his backpack and signed it for Gu Jianguo, and his work was completed.

Gu Jianguo asked the workers to inform him that after the start of work tomorrow, he would take the technician home, and he would be sent back after having a meal at home at noon.

When she got home, Du Xuemei had already prepared the meal, and when she saw them coming back, she hurriedly prepared the hot water.

During the meal, Gu Yun learned that the technician's name was Xu Aiguo, a native of LPS City.

After graduating from secondary school, he first worked as a safety officer in a coal mine, and for some reasons, he went to work as a maintenance and installation master in a motor factory.

As for the reason, Xu Aiguo didn't say, but from his words, some indignation could still be heard, and it seemed that there were still some stories in it.

When asked how much he could earn in a month, this guy didn't hide it, and directly said that 80 yuan a month plus a commission for installation and maintenance can basically earn about 200 yuan a month.

After listening to this, Gu Yun said, "Uncle Xu, are you interested in coming to our coal mine to work?" The treatment is definitely better than before, and you can also mention any conditions. ”

Gu Jianguo, who was on the side, heard his son say this, and his heart was also a little moved, through this incident, he felt that he still lacked a lot of things for opening a coal mine.

And Xu Aiguo in front of him is a person who has a deep understanding of coal mines, otherwise he would not be able to be a safety officer in a coal mine.

And this man is also proficient in equipment maintenance, with him, the mining of coal mines will be much smoother.

Thinking about the joints, Gu Jianguo also opened his mouth and said: "Lao Xu, don't look at my son is still young, but what he said is also what I want to say......"

What followed was a long talk between the two of them, Xu Aiguo did not agree at first, and the work of the motor factory was still very good.

But after hearing Gu Jianguo's monthly remuneration of 1,000 yuan, Xu Aiguo instantly forgot what he had just said, and agreed without the slightest hesitation.

Gu Jianguo's 1,000 yuan, the temptation is really not ordinary, this year, the salary of an ordinary worker in a factory is about 200 yuan.

Even he himself worked hard in the motor factory for a month, that is, more than 200 yuan, and when the benefits were better, he could reach 300 yuan.

It is conceivable how much the impact of 1,000 yuan on him can be seen by looking at his flushed face.

In fact, there is another reason why Xu Aiguo agreed so happily.

After he came here, when he saw the mining situation of this coal mine, he knew that the reserves of this coal mine were very huge.

Working here, as long as he does his job well, there will be no risk of losing his job for at least thirty years.

Since he is already his own person, the next dinner is much more enthusiastic.

This meal was eaten until half past two in the afternoon, and Gu Jianguo and Xu Aiguo were a little drunk, but Xu Aiguo still expressed his intention to go back today to deal with some things.

Seeing that what he said didn't seem to be a lie, Gu Jianguo asked Gu Yun to send him back to the city after he kept it.
