There has never been a person like Xu Yun in the gold mine, so both Chinese employees and local miners were completely shocked.

No one in this gold mine dares to work against mercenaries. Even the big boss of Huaxia is very kind to these mercenaries.

This politeness is definitely not hypocritical, but has a certain fear of their armed forces, so this kind of politeness.

Xu Yun pressed the black mercenary and walked straight in front of the elevator. The people next to the elevator consciously flashed a path and watched Xu Yun open the elevator. Xu Yun did not have any hesitation and went straight in.

The elevator of the gold mine is still falling fast. There is a platform one kilometer deep underground, which can be reached in just over a minute.

There were only Xu Yun and black mercenaries in the elevator. After entering the elevator, the black mercenaries were guilty.

"I was wrong, you forgive me, and I dare not respect you anymore." The black mercenary said: "What do you have to talk to the towers, everything we do is what he means!"

Xu Yun ignored what he meant, and directly pressed the elevator: "I will find the tower to talk about the problem between me and him, but now it is between me and you."

The lift began to buzz down, and Xu Yun also directly released the black mercenaries. The other party wanted to resist, but he was unable to resist Xu Yun.

The elevator quickly reached a platform, and Xu Yun pushed out the black mercenaries.

Xu Yun has a certain understanding of the structure of the underground, so he is very clear about what is inside. But the black mercenary didn't know it, and when he saw the dim light, he felt hairy.

Xu Yun pushed him for a few minutes and walked to the next elevator in another lane. This elevator was responsible for transporting the miners to the deepest operating site.

Someone was in charge next to the elevator and saw that they were a little surprised.

Xu Yun's momentum makes people know that he is an authoritative speaker without further ado, and the two of them took the elevator again and began to fall.

The black mercenaries are all in a mess. He is really afraid that Xu Yun will let him die inside.

Soon they reached a deeper place. When Xu Yun took the black mercenary out of the elevator again, various thick pipes were fixed to the walls of the aisle to send water and fresh air and electrical wires to the ground.

The miners and their equipment, as well as the ore, are transported in the roadway by tram. The ground of the roadway, besides the railroad tracks, is messy bugs, which is very disgusting.

In the noise of generators and trams and various other mechanical equipment, miners shouted at each other in local languages. Some miners also carry broken plastic bottles, which are filled with locally brewed wine. Sometimes working in such a place requires a sip of wine to refresh.

Inside the mine, the horizontal roadway extends from the central shaft in all directions and enters the mining face at various depths. The main roadway has a diameter of seven or eight meters.

The walls and top are reinforced concrete mixed structures, and the steel bars are firmly fixed with the surrounding rocks.

But the closer to the active mining surface, the worse the environment will become. The aisle becomes narrower and narrower, miners can only pass through by bending over, and the headlights will constantly scrape on the aisle.

In the end, everyone can only lie on the ground and crawl forward with their knees. The dim light fell on the stairs leading to different lanes, and looked like an entrance to hell.

There was a lot of dust in the air, and the rust-colored sewage oozed out from the cracks in the wall ...

The working environment in this place is definitely the worst in the world.

However, the miners who mine gold in this place have extremely low wages. Some of them can even get it for only ten dollars a day.

On this continent in Africa, this kind of cheap labor may be the richest thing.

On the mining surface, the tunnel reached the end, and the ore body appeared. The gold mine was mined in these places. The thickness of the ore layer can be from a few centimeters to one or two meters.

The exposed ore layer is smooth on the outside, covered with quartzite, and also doped with pyrite spots. Although this thing is very similar to gold, it is what the miners call "Fool's Gold".

The real gold ore is hidden in the darker-colored stones. These ores will be exploded into billiard-sized stones by the miners, transported to the ground through the transportation track, and then let the workers on the ground handle the crush Things that need to be refined.

Only a step-by-step process will be solved, and eventually it will become the underground vault of major banks, or become a "running chain" in the necks of some tycoons.

The thicker the gold necklace is, the more it can pay back when these **** are in trouble, and it is convenient to run the road to prepare for unexpected needs, so it is called the "running chain".

The black mercenaries were somewhat at a loss. Xu Yun gave him to the workers who were working hard: "Here I will do twenty-four hours of work and then come out."

"What ?!" The black mercenaries were stunned at the time. What was this requirement!

"You can do it if you don't want to do it. If you don't accept the punishment, I will let you die now." Xu Yun provoked.

The black mercenary's legs softened, and he knew that Xu Yun could not beat Xu Yun.

Mercenaries have an advantage, that is, they are particularly self-knowledge, and they will never succeed if they know that they cannot beat them.

"This is a punishment for you. As long as it is you mercenaries, whoever disrespects me, I will send them in!" Xu Yun said: "You better work hard, if I hear who says you are lazy, You will continue to continue for another 24 hours, until you have a five-star reputation, and I will let you come up. "

"Then what do I eat."

Xu Yun spread his hands together: "Anyway, I don't know if the big cockroaches here are foods with high protein."

"I ..." The black mercenary was completely speechless.

Xu Yun pointed to the worker who opened the mine: "Follow him to study hard, and quickly find an air drill to start working! Don't let me see you as boring again."

The black mercenary was helpless and had no choice but to arrange. He also took the air drill bit and started to walk slowly towards the mining site, then climbed down to the mining surface.

Miners used hand-held air drills to drill small holes of two or three centimeters in diameter on the surface of the ore layer, then filled the holes with ammonium nitrate-based explosives, and then conducted remote blasting only after the ground personnel determined the safety.

Drilling and exploding in extremely deep underground, the most people need to overcome is the high heat and increased rock stress in this place.

In large mines, engineers will find a way to deliver a large amount of cold water to the bottom of the mine every day, and then pump it back after the water temperature rises.

More than 500 liters of water are circulated every second in the air-conditioning system pipes located thousands of meters deep underground. To reduce the amount of water consumed during the cooling process, ice cubes were also used by engineers.

But this process still consumes a lot of electricity, so this small gold mine will not use this method to help the workers cool down.

Many people think that Africans are very resistant to heat, even if there is a high temperature close to fifty degrees below it, they can still work.

In addition, mitigating stress in rocks has proven to be far more difficult than maintaining proper temperatures in mines. In Africa, there are countless large and small earthquakes caused by underground blasting, so that seismologists all over the world often go to Africa Of some mines, collect data that can help them understand earthquakes.

The deeper the miners drill and blast, the greater the stress generated in the rock. In addition, due to the large amount of ore being removed, the remaining rocks are also under great pressure.

After the accumulated stress reaches a certain level, the rock will explode violently and suddenly release the energy. This process is as fast as the back of a tight bowstring. It is difficult for those working on the mining surface to survive.

So how dangerous this place is, it goes without saying.
