"Captain Chen, please stay!" Fang Dajun called Chen Zhongjun and said bluntly: "The vermicelli field requires a large amount of clear and clean water, so it will be built upstream. I think the location of the Development Village is very good."

"That's great. Team leader Fang needs any manpower. Just tell me that our production brigade will support it with all our strength!" Chen Zhongjun dared not treat him as a half-grown child now, and called him the team leader directly.

Fang Dajun smiled and said, "That's the best. The county will come to inspect the threshing machine tomorrow. In this way, I will go to the Development Village the day after tomorrow to see the terrain, so that it will not delay Captain Chen's work."

"What can I delay? Secretary Wang and President Zhu both said that the most important thing now is to make vermicelli." Chen Zhongjun has a straight personality. Such a temperament is actually not suitable for being in the officialdom, but being a small leader can be deeply supported by people below.

"That's it, let's talk about the specific one the day after tomorrow!" It was getting late, and Fang Dajun didn't talk much. After a few greetings, he went home.

At the dinner table, my parents had to ask him again. Naturally, he chose to say that there was no bad news at the moment. He drank two big bowls of corn porridge, took a cool down and went to bed early.

Early the next morning, he gave his two sisters another five cents. The two sisters held hands and ran to school happily with a small backpack!

He cleaned up and changed into a set of coal-dig work clothes that could not be washed without washing. He put on a safety helmet woven with rattan. After thinking about it, he put the black stone wrapped in red cloth into his pocket, and got up wherever he fell.

He planned to see the current coal cave with his own eyes. Although there were too many scenes of digging coal in his memory, it was still not as clear as what he saw with his own eyes.

In fact, the most important thing in coal mines is safety measures, and the most important thing is to prevent gas explosions. Once a gas explosion occurs, casualties will be extremely heavy.

After actually inspecting the coal cave, he will start to write homework instructions, train coal miners, and write safety knowledge tests. Only after passing the qualification can he enter the coal cave to work.

CH4+202—CO2+2H20, this is the equation of gas explosion. Downhole smoking, electrical sparks, illegal fire firing, open flame operations, etc. are all likely to cause gas explosions. To put it bluntly, it is a hot-chain reaction when gas gas reaches a certain concentration that encounters a high-temperature ignition source and produces oxygen in the air.

It is actually simple to prevent it. Test the concentration of gas in the mine. If it is too high, some gas will be removed. In addition, it is fire protection. The high temperature of about 600 degrees will cause gas to explode. Therefore, small flames like smoking are basically impossible to detonate gas, but it is not absolute. This person will be shot when he is unlucky.

Another important reason for detonation is the friction between metal tools and coal. Coal is a burning substance. If the friction is too large, it is equivalent to friction flint. The temperature at that moment is very likely to detonate the gas that reaches concentration. As for oxygen, people breathe inside, and oxygen is naturally sufficient.

However, gas explosions are generally only prone to being shot by large coal mines. It is almost impossible for gas explosions like the purely manual earth and coal caves like Jiaoshan Commune to have gas explosions. It is almost impossible for him to plan ahead. It is difficult to become a billionaire with such a small coal mine. Large coal mines must be built later.

As he thought about it, he walked towards the coal cave of the production brigade. The location was not far from the pig farm. More than twenty minutes later, he came to the place. This was a cave that was manually dug directly into the hillside. It was two meters high and about three meters wide.

The spring water was flowing out of the coal cave, very small, but it was flowing slowly. The air was filled with a deep and cold smell of coal. I squatted down and touched the spring water, and I felt it was biting cold, but very clear. Unfortunately, there was also the smell of coal in the water, so people could not drink it.

He didn't rush into it, but waited for a while at the entrance of the cave, but saw Qin Er dragging a coal truck out slowly. The structure of the coal truck was very simple, with two wheels and two long handrails on the left and right. The handrail is a Nanzhu rod. The carriage is also made of Nanzhu, which is more than one meter wide and more than two meters long. It can only be pulled half a ton at a time. If there is more coal, people will not be able to pull it.

Even so, this half ton of coal is very difficult to pull, and those who are not strong and cannot do it.

Qin Er then put on a classic shape of MJ tilting forward thirty degrees, just like the world-famous painting "The Boatman on the Volga River". A thick hemp rope was slanted on his shoulder and connected to the coal truck behind him. He grabbed the handrail of the coal truck with both hands, and then leaned forward and pulled the coal truck forward step by step.

Fang Dajun was repeating this action before, which seemed very miserable, but after getting used to it, he got used to it.

Also because the road has been marked by the wheels and there is no upward slope, it will have some inertia when pulling up coal. Once the coal hole is out, it will be downhill, and it is easy to pull to the coal site.

The difficulty is the distance inside the coal cave, so this kind of earth coal cave usually won’t be mined for long, because once the route is extended, the energy wasted on transporting coal is too amazing.

In the future, mines with abundant coal reserves must be equipped with rails and use the tracks to transport and export coal from the mines.

"Da Army, why are you here?" Qin Ergang raised his head and saw the army distracted, and shouted quickly.

Fang Dajun smiled, "I'm not resting for a few days and feeling uncomfortable all over, so I want to come to the coal cave to take a look."

"What's so good about this? Wait a little longer. I'll pull this car out and finish the work." Qin Er said happily. The task of a full-time worker was about half a ton of coal. Of course, he couldn't dig out a car so quickly, but he was working with Qin Da. He pulled out a car first and went back to help Qin Da get another car. Hurry up and the two brothers could finish the work by noon.

In the afternoon, I either go to have sex or do some farm work at my own house. Because of this, even though I am tired of digging coal, there are not many people who are willing to do it.

This coal cave belongs to Xinqiao Brigade, with only seven people digging coal, and about four tons of coal is produced a day, because uncle Li Jianjun dug one ton alone, and he can be regarded as the best man in the brigade!

"Haha, I'll pour coal with you, and then accompany me to the coal cave to take a look." Fang Dajun said. Although he didn't want to admit it, he was a little scared of the dark coal cave. This was simply a scam and speechless to himself. There was no way. Although he evaluated that this kind of earth and coal cave generally could not have safety accidents, as a modern person's mind, he had an instinctive resistance to this dangerous work.

This is a pity. He still hopes to mine coal and become a billionaire. If he doesn't dare to enter the coal hole, isn't this a joke?

"It's done, when I help my brother dig the coal, we'll go and have fun in the afternoon!" Qin Er wiped the sweat from his forehead, but his face was blurred, as dark as Bao Gong.

More than ten minutes later, Qin Er handed over the coal, got the work today, and then he went into the coal cave with Fang Dajun talking and laughing.

The dark coal cave exudes a cold, like the ferocious beast that swallows flesh and blood, opening its huge mouth, making people shudder!

Moreover, there is no lighting in the coal cave, only a few kerosene lamps are lit at the bottom to facilitate everyone to dig coal. At present, there is not even a portable mine lamp. The conditions are so simple. It is because the kerosene lamps have always been working, and there is open flame in the cave, so he is sure that it is difficult for gas explosions in such a soil and coal cave.

Because the commune has never had a gas explosion since its coal mining, like Qin Daqin Er, I am afraid that he doesn't even know what the gas explosion is.

"Hurry up, what's wrong with you today? You used to be the fastest." Qin Er's urging voice echoed in the coal cave where he couldn't see his fingers.

Fang Dajun really wanted to slap himself. The main road of the coal cave was hit straight in. He just needed to lift his foot and walk. Even if he couldn't see it, he wouldn't get lost. He could quickly reach the coal mining site by walking a few more times, not to mention that he had been walking on this road for a year before.

"Oh, isn't my body still alive? You should go slowly!" Fang Dajun lied. In fact, he made a move of spreading his wings at this time and was exploring and moving forward carefully.

"Hello, let's chat while walking, Dajun, what meeting did you go to yesterday!" Qin Er looked for the topic.

Qin Er is his own person, so Fang Dajun did not shy away and roughly explained the content of yesterday's meeting, which made Qin Er exclaim. Finally, Fang Dajun suddenly realized that the people now are so easy to fool, and it should be said that they are so easy to deceive. If he switches careers and becomes a liar now, he is afraid he can make a fortune!

Perhaps it was because the chat relieved the fear, or perhaps it was the habitual instinct that the original owner of the body had developed before, he gradually put down his fumbled arms and could move freely. Every time he took a step, he no longer worried about hitting the hole wall, nor did he think about the sudden explosion of the coal hole, landslide, etc.

Until the sound of excavating coal was heard, the two had walked more than a mile inside. The coal hole directly penetrated into the belly of the mountain. The road was always flat and almost straight. Perhaps because there were no curves, the air in the coal hole could circulate with the outside, and even if there was gas gas, it was diluted by the circulating air.

It is also because there are not many coal miners and their destructive power is not that great. Sometimes it is not a bad thing to achieve half the result with twice the effort. If you work slowly and do it hard, it is not easy to have accidents.

As for the time he was buried, he was completely destroyed for eight lifetimes, which is an extremely small probability event!

After walking for a while, I finally saw the light, and the sound of digging and knocking became louder and louder, and there were also intermittent speeches.
Chapter completed!
