Daming Yuanfu

Chapter 750 How did the population come?

Going south from Yingdu Mansion, the first stop is Hehua Mansion.

The location of Hehua Mansion is the Hejing of the later generations, and the main urban area basically has not changed, so it is very convenient and pragmatic to determine the location of the iron mine.

How to be sure?Gao Yushi once had two memories of the Shixi Iron Mine in Ha Tinh. One is that it is close to the sea, not far from the sea; the other is that it is only eight kilometers away from the downtown area of ​​Ha Tinh.With these two "coordinates", it is certainly not difficult to determine the general location.

After he wrote to Liu Xin last time asking about the distribution of Annan's minerals, Liu Xin's reply was a hundred times more clear.

Liu Xin said that the Changshan fold belt is one of the very important iron, copper and gold polymetallic metallogenic belts in Southeast Asia. There are many large or even super large deposits in the belt, the most famous of which are the Shixi Iron Mine, the Peng Miao Gold Mine, Fushan Gold Mine, Sepan Gold Mine, Fukang Gold Mine, Mount Lishan Iron Mine, Fu Nuoan Iron Mine, etc.

However, Liu Xin also seemed to have guessed what Gao Yushi was going to do, and specifically pointed out a few areas that were relatively easy to mine and the transportation might be more convenient, such as the iron mine in Ha Tinh and the gold mine in Da Nang.

Of course, when it comes to iron ore alone, Ha Tinh Shixi Iron Mine is the most important. This iron ore is the largest skarn-type magnetite-rich ore in Southeast Asia. It not only has more than 6 million tons of reserves, but also has an average grade of up to More than 61%, hooking the vast majority of iron mines in Daming.

However, troubles are not without. The biggest trouble lies in the reserves of more than 6 million tons. Gao Wushi can only use a small part of it now, because although this mine can be directly mined in the open pit, the total depth of the ore body is terrible. The exploration results of later generations It reaches more than 400 meters below sea level.

It is unimaginable to dig below 400 meters below sea level in this era, especially since it is located by the sea, and there may be groundwater or something, so Gao Pragmatic can only dig the surface layer, and dig down to a maximum of ten or twenty feet. That's about it.

Fortunately, this is enough—it’s not just that he is too pragmatic to dig deep these days, no one in the world can dig too deep.That being the case, what are you worried about?I'm really afraid that there will be no iron mines. Wouldn't it be a pleasure to occupy Australia first in the future.Anyway, the surface part of the Shixi Iron Mine can be excavated for at least 100 years based on the production scale set by the high pragmatism.

The second complication is the supply of coking coal.Since Gao Wu has provided the coking coal technology for ironmaking in Daming, he has always used coal to make iron and steel, so the demand for coal is not small.However, not all coal can be used for ironmaking. The most important use of coal in the ironmaking industry is coking, and the main coal used for coking is coking coal.

There is a lot of this kind of coal in Ming Dynasty, but Annan’s coal is famous for its high-quality anthracite, which is roughly a kind of low-impurity steam coal—if this is the era of steam power, it is of course good news that there are more high-quality anthracite, but now But not necessarily, the use of anthracite is relatively single, even with Jinghua’s technical level, it can only be used as a fuel for blast furnace injection and sintering iron ore, and as a foundry fuel.

Useful is useful, but the coking coal is still not solved.

There is a coal mine not far northwest of Ha Tinh, and it is not difficult to dig it, but according to Liu Xin’s memory, the coal in that place is mainly anthracite—it can be dug, but it is not necessary, because Liu Xin provided another supply place .

This place of supply is the later Honji Coal Mine, which is located near Halong Bay in the northeast of Annan, and is the largest coal mine in Southeast Asia in later generations.Although the coal mines here are mainly anthracite coal, in general, there are still a lot of coal types, which can fully provide coking coal and other types of coal with sufficient high practical demand.

In fact, the Daming used earth kilns to make coke and coke to smelt iron before the high-practice time travel, but the technical content was very low, and the quality of the smelted iron was not good.

After Gao Pragmatic’s crossing, two types of earth kilns, the round kiln and the long kiln, were developed on the basis of the original technology of the Ming Dynasty. The former is suitable for areas with low groundwater levels and good coal coking; , the operation is less affected by groundwater, and the coking time is shorter, and it is suitable for rainy areas where coal coking is slightly poor.

However, Gao Yushi also knows that the characteristics or shortcomings of earth kilns are that the coking chamber and the combustion chamber are not separated, and the heat source for coking is provided by the gas generated during coal dry distillation and the combustion of part of the coal material, so the coking rate is low, the coke ash content is high, and coking Long time (approximately 8-12 days and nights)——As for chemical products that cannot be recycled, serious air pollution, etc., he ignores them.

It’s not enough to just know it, and he has to find a way to improve it, but he has been working on it for several years without success. Later, he provided ideas and asked Zhu Zaiyu to help design and improve, and finally came up with a round kiln with a fixed vault. , known as honeycomb coke oven.

The coal loading capacity of each hole of this coking oven is about [-] jin, the coking time is reduced to two to three days, the efficiency is greatly improved, and the coking quality is also extremely excellent in this era, which ensures that Jinghua is the leader in steel production status.

These two circumstances determine one thing: the Ha Tinh Iron Mine can be developed, but it needs to provide coal from the Ampang Xuanfu Division that has been privately "allocated" to the Huang family.

It must be a dream to expect Huang Zhiting and her family to find a way to dig coal by themselves. Gao Pragmatic must let Jinghua participate, and he must take the lead—of course, it is not good to lead in profit, but he must lead in production.

So after talking with Huang Zhiting, he sent someone to deliver a letter to Gao Xiaozhuang, asking him to prepare to send someone to "aid Vietnam".

The main reason for passing through Ho Hua Mansion was for the iron mines, but when he arrived in Hue, Gao Yushi did not stay much. While telling Gao Yu and others to quickly recruit the Annan army under Ruan Huang's department in Hue, he continued to go south with his family guards. Going to Da Nang in his mind.

Hue is not far from Da Nang, only about 100 miles away, and arrived at this bay in less than three days.

This place is really just a small fishing village now, with a huge bay, with a radius of tens of miles, and a population of less than a thousand households, which is not as large as the family guards brought by Gao Yushi.

The Jinghua Fleet also sent some ships to Da Nang under the assignment of high pragmatism to investigate the conditions of the harbor.

But Gao Jing, Boss Hu, and Boss Li also raised a question to Gao Yushi: the commercial port is easy to build, but where is the market?
The location of Da Nang has already entered Guangnan. It is the southernmost Xuanfu Division in Annan. Well, Annan was originally the land of the Nanman, but this place is actually the Nanman of the Nanman. It just sounds like there is no business opportunity.

The first priority of a business opportunity is someone. Why is there no one talking about business opportunities?But what this place lacks is people!
However, they can think of this, how can Gao Yushi not think of it?Although a large part of the reason why he built Da Nang was to build a bridgehead out of Nanyang, he didn't intend to make a loss-making business—at least in the long run, he couldn't lose money.

Therefore, Gao Wushi said to them very calmly but in a spirited manner: "Don't worry about this matter, there will be a population soon, because in Guangnan... there are at least two large gold mines."

"Big gold mine?" Gao Jing and the three of them opened their eyes wide open.

Boss Hu hurriedly asked, "How big is the gold mine? How did you know about it?"

Of course, Gao Wushi couldn't say that Liu Xin told him, so he could only continue to play tricks and said, "How do you know? I'm supposed to be observant, don't you know?"

Oh...there is such a legend, after all, there is no one in the world who can match the foresight of high-level ore prospecting.

Boss Hu and Boss Li got excited, rubbing their hands together and asked in unison: "I see, how much gold can these two big gold mines have?"

Gao Yushi said indifferently: "One of them has at least 400 million taels of gold reserves."

"Hiss—" the two of them, oh no, Gao Jing was added, and the three gasped suddenly.

"Four... four hundred... ten thousand taels?" Boss Li trembled as he spoke, as if he was wobbling.

"400 million taels...is it just one of them?" Boss Hu's situation is not much better than that of Boss Li, like a pair of brothers in distress.

Gao Wushi smiled and said, "Yes, one of them."

He is really not joking. This is a gold mine that Liu Xin specially explained, which is the Pengmiao gold mine in later generations. Its reserves are estimated to be 200 tons, which is 400 million taels. Uncertain 500 million taels is also possible.

400 taels of silver has already made countless people rob their heads, so what is the concept of 400 taels of gold?
Not to mention anything else, as long as Gao Wushi releases the news, even Daming does not know how many gold diggers will come to him—humanity's desire for gold has almost never diminished!And there is no distinction between Chinese and foreign.

At this moment, Boss Hu and Boss Li even wanted to change their careers and come here to seek gold.

It's a pity that Gao Wushi immediately extinguished their hopes, because Gao Wushi said: "However, Guangnan is so big, with a radius of hundreds of miles, but the approximate location of these two gold mines is only known..."

The golden flames in the eyes of the two bosses had just risen before being extinguished.

That's right, so what if there are gold mines, this is not tens of miles in radius, but the Nanban area with a radius of hundreds of miles. Only the high presses know the location of the two big gold mines, so what's the use of us?

Can you find it?Can you dig it?Are you lucky?

"Then, how do you plan to develop these two major gold mines?"

Gao Wushi smiled, and said: "The two bosses are smart people, and they really know a little bit-let's put it this way, one of the mines, I, Jinghua, wants it myself; and the other mine, Jinghua doesn't want it, it is specially used to attract gold diggers. customers. And then... This plan will open a flight, divided into multiple routes, to transport these gold diggers from Daming China continuously. If you two are interested, you can also participate in this matter and spread the news widely. for dissemination."

Oh...so that's what happened.
