There has never been a person like Xu Yun in the NN gold mine, so both the Chinese employees and the local miners were completely shocked.
No one in this gold mine dared to fight against the mercenaries, even the big bosses of Huaxia were very polite to these mercenaries. nnnn's politeness is definitely not hypocritical, but there is a certain fear of their armament, which is why there is this politeness. nnnn Xu Yun pressed the black mercenary and walked straight to the elevator, and the people next to the elevator all consciously dodged a way, and saw Xu Yun open the elevator, Xu Yun didn't hesitate at all, and walked in directly.
The elevator descent of the NNNN gold mine is still very fast, and there is a platform at a depth of one thousand meters that can be reached in just over a minute.
There were only two people in the NNNN elevator, Xu Yun and the black mercenary, and after entering the elevator, the black mercenary made a mistake. nnnn "I was wrong, you forgive me, I don't dare to be disrespectful to you anymore."
The black mercenary said: "What do you have to talk to the towers, everything we do is what he meant" nnnn Xu Yun ignored his meaning at all, and pressed the elevator directly: "I will talk to the towers about the problem between me and him, but now the problem is between me and you."
The nnnn elevator began to hum down, and Xu Yun also directly let go of the black mercenary, the other party wanted to resist, but he was powerless to resist in the face of Xu Yun.
The nnnn elevator soon arrived at a platform, and Xu Yun pushed the black mercenary out. nnnn has a certain understanding of the structure of this underground shaft, so he knows very well what is in it.
But the black mercenary didn't know, and when he saw this dim light, his heart was furious. nnnn Xu Yun nudged him for a few minutes to the next elevator in another aisle, which was responsible for transporting the miners to the deepest operating points.
There was someone in charge next to the NNNN elevator, and it was a little surprised to see the two of them. nnnn Xu Yun's momentum doesn't need to be said to let people know that he is an authoritative speaker, and the two of them got on the elevator again and began to fall. nnnn's black mercenary's mind was all messed up, he was really afraid that Xu Yun would let him die in it. nnnn soon they were further into the depths, and when Xu Yun came out of the elevator again with the black mercenary, various thick pipes were fixed to the walls of the laneway, carrying water and fresh air and wires underground.
The NNNN miners and their equipment, as well as the ore, were transported by tram through the tunnels, which were filled with dirty bugs and disgusting insects on the ground except for the rails.
Nnnn Amid the cacophony of generators and trams, as well as various other mechanical equipment, the miners shouted to each other in the local language.
Some of the miners also carry torn plastic bottles filled with locally brewed liquor, and sometimes working in such places requires a sip of wine to refresh themselves.
In the NNNN mine, horizontal workings extend from the central shaft in all directions to the mining face at various depths, with the main workings measuring seven or eight meters in diameter.
The NNNN walls and roof are a hybrid structure of reinforced concrete, with the steel firmly anchored to the surrounding rocks. nnnnBut the closer you get to the active mining face, the worse the environment becomes.
The aisles became narrower and narrower, and miners had to bend down to get through, and their headlamps would constantly scrape to the top of the aisles.
In the end, everyone had to lie on the ground and crawl forward on their knees.
The dim light falls on the stairs that connect the different laneways, making it look like an entrance to hell.
There is a lot of dust in the air, and rust-colored sewage is constantly seeping through the cracks in the walls, and the working environment in places like NNNN is definitely the worst in the world.
However, the miners who mine the gold in this area are paid very low wages, and some of them can do it for as little as ten dollars a day.
This kind of cheap labor is probably the richest thing on the continent of Africa.
At the end of the tunnel, the ore body appears, and it is in these places that the gold ore is mined.
The thickness of the ore layer is possible from a few centimeters to one or two meters.
The surface of the exposed ore layer of NNNN is smooth, wrapped in quartz stone, and mixed with pyrite flecks, which although it resembles gold, it is what the miners call "fool's gold".
The real gold ore of NNNN is hidden in darker stones, which are blasted into billiard-table stones by miners, transported to the surface by transport rails, and then processed by workers on the ground, which are then refined.
Only when the step-by-step process is solved will nnnn eventually become the underground vaults of major banks, or the "running chain" in the necks of some ruffians and gangsters.
The thicker the gold necklace is nnnn, the more it can repay the money when these bastards are in trouble, so that it is convenient to run away in case of emergency, so it is called "running chain".
The nnnn black mercenary was a little dazed, and Xu Yun pushed him into the workers: "Do things for twenty-four hours here, and then come out."
"nnnn" What" The black mercenary was stunned at the time, what kind of request is this nnnn "If you don't want to do it, it's okay, if you don't accept the punishment, I'll let you die a happy death now."
Xu Yun said provocatively. nnnn The black mercenary had weak legs, and he knew that he couldn't beat Xu Yun.
NNNN mercenaries have an advantage, that is, they are particularly self-aware, and they will never be strong when they know that they can't beat people. nnnn "This is your punishment, in the future, as long as you mercenaries, whoever treats me with no respect, I will send whoever comes in" Xu Yun said: "You better work hard, if I hear someone say that you are lazy, you will continue to continue for another twenty-four hours, until you have a five-star reputation, I will let you come up."
"nnnn" So what do I eat. nnnn Xu Yun spread his hands: "Whatever, I don't know if the big cockroaches here are super high protein foods."
"nnnn" I" black mercenary was completely speechless. nnnn Xu Yun pointed to the workers who opened the mine: "Follow him to study hard, hurry up and find an air drill and start working, don't let me see you so boring again."
The nnnn black mercenary had no choice but to let it go, and he took the air drill bit and began to walk slowly towards the mining site, and then crawled over with his waist down until he reached the mining face.
NNNN miners use hand-held air drills to drill small holes with a diameter of two or three centimeters in the surface of the ore layer, fill the holes with ammonium nitrate-based explosives, and then blast them remotely after the ground personnel determine the safety.
NNNN drills and blasts deep underground, and the most important thing to overcome is the high heat and increased rock stress.
In general, engineers will find a way to transport large quantities of cold water to the bottom of the mine every day, and pump it back when the water temperature rises.
The pipes of the air conditioning system, which is located thousands of meters underground, circulate more than 500 litres of water per second.
In order to reduce the amount of water consumed during the cooling process, some engineers used ice cubes.
But this process still consumes a lot of electricity, so this kind of small gold mine will not use this method to cool the workers.
In the eyes of many people, Africans are very tolerant of the heat, even if it is close to 50 degrees Celsius down here, they can still work.
In addition, mitigating stresses in the rock has proven to be much more difficult than keeping the right temperature in the mine, and there are so many large and small earthquakes caused by underground blasting in Africa that seismologists around the world often travel to mines in Africa to collect data that will help them understand earthquakes.
The deeper NNNN miners drill and blast, the greater the stress in the rock.
In addition, the large amount of ore being taken away also puts the remaining rock under tremendous pressure.
After the stress build-up is so high that the rock explodes violently, releasing energy suddenly, the process is as swift as a taut bowstring bouncing back, and those working on the mining face will hardly survive. nnnn So how dangerous this place is, it goes without saying. isjgniitfreeti0:
