A few years ago, dozens of miners lost their lives each year in many of these privately contracted gold mines on the African continent.

So there was a very big change in the mining plan, the owners of the mine were smart, and the mining of ore was no longer concentrated in one place, so that they would not have to pay for the dead.

Just like the mine site in Lai Wen, the miners are even in all areas of the mine, leaving more rock pillars as support, and at the same time, they also carry out large-scale backfilling, crushing the waste rock extracted on the ground. Transport back downhole to fill the mined area.

This is a very necessary method, after all, any supporting point is not as good as the rock itself.

In fact, there is a more important point, but there is no such small mine.

Advanced monitoring systems are installed in the deep wells of some large mines. A large number of battery-sized sensors installed in the holes in the underground rocks constitute a huge monitoring network.

These sensors collect seismic signals and transmit them to computers on the ground. In this way, it is convenient for geophysicists with professional knowledge to analyze these data, and directly close the mining areas that are in a high-risk state to completely prevent the occurrence of danger.

But that's all for large mines. For Lai Wen's mines, what he needs to worry about most is whether the gold mines mined each year can make enough money. After all, such places need to pay rent.

If the local country is capable of mining, this kind of good thing will not be their turn.

The domestic gold mining competition is fierce to an unprecedented level, so more and more Chinese will come to Africa to find gold. This kind of thing is naturally known to Wen Wen, so he also has a sense of crisis. This sense of crisis lets him know that the more cost savings The more efficient.

Even if it is really dangerous, it is not the person he cared about that died, he does not matter.

In fact, in addition to the gold mines in Mali, Lai Wen also has other gold rushing businesses.

There are also gold diggers he hires in Ghana. Most of Ghana ’s gold comes from alluvial deposits in streams and rivers in the central rainforest, and in the sand on the banks of the river.

Lai Wen brought a more efficient and faster production method. The same area of ​​the mine will be mined by the Ghanaian for several years, while the Huaxia heavy machinery brought by Lai Wen was dug in half a year.

Moreover, Lai Wen has always been pursuing the amount of gold produced, and does not seek intensive farming at all. Once the mining situation is not good, he immediately moves to another piece of land, which greatly undermines the local people ’s gold mining rules.

Xu Yun has already returned to the "surface of the earth" with a lift. This feeling is really surprising.

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. So most Malians are concentrated in southern Mali, where the Niger and Senegal rivers originated.

Eighty percent of the labor force in this country is engaged in agricultural work, but only a few lands in the country are agricultural land, perhaps only two percent.

This is definitely one of the "least developed" countries in the world. Although it is not the last to last, the global comprehensive development of the country is definitely in the top ten of the countdown, and one can accidentally fall into the top three of the countdown.

193 countries in the world are like 193 people in a class. You got 180 or 90 in the exam. In fact, there is not much difference in the countdown to the top ten. Everyone who has gone to school You know, it ’s just who is better, and whoever makes the wrong choice may change the ranking.

In addition, this ghost place is also a place where no one is in control. Because the soldiers are dissatisfied with the pension policy, the presidential government is directly ended. It is so hard!

Therefore, the mercenaries in the streets are not uncommon in this country.

Xu Yun came out under the mine, but the black mercenary did not come out, and the other mercenaries felt a little hairy.

This is called killing chickens and monkeys. Many leaders or leaders in China like to use this trick to set their majesty.

Xu Yun now puts out this trick and puts it in this place, which is definitely useful.

The mercenaries don't know what it means to kill chickens and monkeys. They only know that this "leader" dares to treat this guy like this, just dare to deal with them.

It's that simple. No one wants to be the next bad luck.

No one dared to question Xu Yun. Xu Yun walked straight to the door of the best Banfang and pushed the door inwardly.

The room was obviously clean and rare, but it seemed messy.

A huge wooden bed with messy futons, a tiger chair sofa, a coffee table, and a large row of bookshelves and cupboards opposite the bed. What surprised Xu Yun most was that this room was actually set up Separate bath and toilet.

Lighters and cigarettes were scattered on the bedside table, and some wine was scattered on the coffee table. Both vodka and whiskey were available, some were unopened, some took a sip, and some left a bite.

Xu Yun frowned and walked out of the room. When he saw a Chinese person working near the ground, he greeted directly: "You asked a few people to come and help me clean this room. Also, arrange for someone to go out and buy me a bed. I ’m not familiar with the new bedding. "

The man was dumbfounded at that time, looked at Xu Yun, and said blankly: "This ... this is the tower's room."

"Don't you understand the human language? Facial paralysis sent me to this place, just to manage these mercenaries, and the towers are included." Xu Yun said: "This separate room should be my stay, not he."

This person really convinced Xu Yun's boldness, but the Huaxia people always have a characteristic, that is, the slavery after encountering the strong.

Just like the person in front of him, although he was worried that the towers would rise, he called a lot of people to participate in the principle of the law not blaming the public.

He also did this to avoid guilty of the guy who seemed to offend him.

For them, all they need to do is work hard to make money. As for this place, whoever has the gun will have the final say, and who has the ability to suppress everyone, the last one will have the final say.

Everything went very quickly. The Huaxia people paid attention to speed. Xu Yun's room was quickly packed, and the person who bought him the quilt was also bought back, and immediately arranged for the person to clean the futon cover and then dry it. .

The room was soon renovated.

All mercenaries are biting their teeth, they are thinking about a question, why is this, why is this guy so bold, why is this guy so bold.

This is the room of each tower. He actually wants to be the king in this place? !

Just kidding, this is in Africa, but there is no Mali with a decent regime.

In this place, Xu Yun is also quite boring. He lifts his legs, squinting and begins to enjoy a pleasant rest. First, the plane was bumpy all night, although Xu Yun also had a rest, but it was impossible to take a rest very comfortable.

As soon as he arrived at the mine, he clashed with the armed mercenaries here. He went to the mine and educated people. He also had to wait for his men to clean up the room.

Now that everything is settled, Xu Yun finally has a good night's sleep.

However, the good times are not long, Xu Yun just lay down, and a huge car engine roared outside.

It seems that someone came again, and dare to drive here like this, obviously still a bit of status.

But Xu Yun could not care so much, at this moment he just wanted to sleep.
