A few years ago, dozens of miners were killed every year due to rock bursts in many of these privately contracted gold mines on the African continent.
So the mining plan has undergone a very big change. The owners of the mines have become smarter and the ore mining is no longer concentrated in one location, so that they do not have to pay pensions for the dead.
Just like this mine in Laiwen, miners evenly spread out the various areas of the mine, leaving more rock pillars as supports. At the same time, they also carried out large-scale backfilling, crushing and extracting waste rocks on the ground and then reclaiming them.
Transport it back underground and fill in the areas that were mined.
This is a very necessary practice, after all, no support point is as good as the rock itself.
In fact, there is a more important point, but it is not available in such a small mine.
Advanced monitoring systems are installed in the deep wells of some large mines. A large number of battery-sized sensors drilled into the underground rocks form a huge monitoring network.
These sensors collect seismic signals and transmit them to computers on the ground. This allows geophysicists with professional knowledge to analyze the data and directly seal those mining areas that are in a high-risk state to completely eliminate dangerous mines.
occur.
But that's all for large mines. For Lai Wen's mine, what he needs to worry about most is whether he can make enough money from the gold mines he mines every year. After all, this kind of place needs to pay rent.
If the local country has the ability to mine, such a good thing will not be their turn.
Domestic gold mining competition is fierce to an unprecedented level, so more and more Chinese will come to Africa to dig for gold. Lai Wen naturally knows this, so he also has a sense of crisis. This sense of crisis makes him know that the more cost-saving
The more efficient it is.
Even if there is real danger, the people who die are not the ones he cares about, so he doesn't care.
In fact, in addition to the gold mines here in Mali, Lai Wen also has other gold mining businesses.
He also hired gold diggers in Ghana. Most of Ghana's gold comes from alluvial deposits in streams and rivers in the central rainforest, as well as from the sand on the river banks.
Lai Wen brought a more efficient and faster production method. It would take Ghanaians several years to mine the same area of mine, but the Chinese heavy machinery Lai Wen brought could dig it out in half a year.
Moreover, Lai Wen has always been pursuing the quantity of gold produced, not intensive farming at all. Once the mining volume is not good, he will immediately move to another piece of land, which greatly undermines the local gold mining rules.
Xu Yun has returned to the "surface of the earth" in the elevator. This feeling is really enlightening.
Although this land is so barren, it is much better than underground.
As the second largest country in West Africa, Mali's northern border is the center of the Sahara Desert. Therefore, most Malians are concentrated in southern Mali, where the Niger and Senegal rivers originate.
Eighty percent of the country's labor force is engaged in agricultural work, but only a very small amount of land in the country is agricultural land, maybe only 2%.
This country is definitely one of the "least developed" countries in the world. Although it is not ranked at the bottom, the comprehensive development of countries in the world is definitely in the bottom ten. If you are not careful, you can fall into the top three.
There are one hundred and ninety-three countries in the world, just like there are one hundred and ninety-three people in a class. If you get 180 or 90 in the exam, there is actually not much difference between the top ten and the bottom. Everyone who has gone to school has
You know, it's just a matter of who gets the better of the situation, and whoever gets the wrong choice may have a change in ranking.
Also, this ghost place is also an uncontrolled place. Because the soldiers were dissatisfied with the pension policy, they directly ended the presidential administration. It was so hard!
So it is not unusual for this country to have mercenaries on the streets.
Xu Yun came out from the mine, but the black mercenary did not come out. The other mercenaries felt a little scared.
This is called killing chickens to scare monkeys. Many leaders or managers in China like to use this trick to set their own dignity.
If Xu Yun takes out this trick and puts it in this place now, it will definitely be useful.
Mercenaries don't know what it means to kill a chicken to scare the monkeys. They only know that if the "leader" dares to do this to that guy, he will also dare to deal with them.
The thing is that simple, no one wants to be the next unlucky guy.
No one dared to question Xu Yun, so Xu Yun walked straight to the door of the best room and pushed the door open without ceremony.
The room was obviously very clean for a place like this, but it seemed very messy.
A huge wooden bed with messy bedding, a tiger chair sofa, a coffee table, and a row of large bookshelves and cupboards opposite the bed. What surprised Xu Yun most was that there were actually
Separate shower room and toilet.
There were lighters and cigarettes scattered on the bedside table, and some wine, including vodka and whiskey, scattered on the coffee table. Some were unopened, some had just one sip, and some had only one sip left.
Xu Yun frowned and walked out of the room. When he saw the Chinese people working on the ground nearby, he greeted directly: "Call a few people over to help me clean this room, and arrange for someone to go out and buy me a bed."
The bedding is new and I’m not familiar with the place.”
The man was dumbfounded at the time. He looked at Xu Yun and said with a blank expression: "This... these are the rooms in each tower."
"Don't you understand human language? Facial Paralysis sent me to this place just to take care of these mercenaries, including the towers." Xu Yundao said: "I should live in this kind of separate room, not
he."
This man was really impressed by Xu Yun's boldness, but Chinese people always have one characteristic, and that is their servility after meeting a strong person.
Just like the person in front of me, although he was also worried that the towers would go crazy, he called many people to participate based on the principle that the law does not punish everyone.
He also did this so as not to offend the guy in front of him who he seemed to be unable to offend.
For them, all they need to do is work hard and make money. As for this place, whoever has the gun has the final say, and whoever has the ability to suppress everyone has the final say.
Everything went very quickly. Chinese people pay attention to speed when doing things. Xu Yun's room was quickly tidied up. The person who bought him a quilt also bought it back and immediately arranged for someone to clean and dry the quilt cover.
.
The room quickly looked brand new.
All the mercenaries were gnashing their teeth. They were all thinking about one question: why on earth is this? Why is this guy so bold? Why is this guy so bold?
This is the room in each tower. He actually wants to dominate this place?!
Are you kidding? This is Africa, and this is Mali, which does not have a decent political power.
Xu Yun was quite bored here. He crossed his legs, squinted his eyes and began to enjoy a pleasant break. First, the plane was bumpy all night. Although Xu Yun also had a rest, it was impossible to rest at all.
Comfortable.
As soon as I arrived at the mine, I had a conflict with the armed mercenaries here. I had to go into the mine and educate people, and I had to wait for my subordinates to clean up the room.
Now that everything has settled, Xu Yuncai can finally sleep well and comfortably.
However, the good times did not last long. Just as Xu Yun lay down, there was a huge roar of a car engine outside.
It seems that someone is here again, and he dares to drive like this here. He is obviously a person of some status.
But Xu Yun couldn't care about that much. At this moment, he just wanted to sleep.
