Chen Fengzhi was also a child from a poor family when he was young.

It was probably when he was in his teens that things got better at home.

At that time, Chen Fengzhi was hiding in Tibet with his grandparents and mother all day long, and he stayed in hiding for two or three years.

Chen Fengzhi was still young at that time, and he still didn't quite understand why they were hiding like this.

I always thought I was escaping from the war.

It wasn't until he grew up that Chen Fengzhi understood why they had to hide back then.

His father rebelled against Great Qin, how could they, his immediate family members, not hide?

Before the rebellion is successful, of course, you have to hide as far as you can.

At that time, the families of these people were basically in the same situation.

It was not until the establishment of the Han Dynasty that these people saw the light of day again.

After the Han Dynasty destroyed the Qin Dynasty, these people's worries were completely gone.

In a sudden change, they changed from rebels to entrepreneurs and conquered the country.

One by one, they have transformed from poor common people into the new rich of the Han Dynasty.

Of course, Chen Fengzhi doesn't want to show off this now.

His family tradition and rules do not allow him to show off these things.

If not, wouldn't people here know that Chen Fengzhi is Chen Tieshan's son?

And he is also the eldest son, the future successor of Marquis Guangwu?

"Li Huai, can you tell me about your prospecting?" Chen Fengzhi had a drink with Li Huai and then started to ask.

"Really talking about prospecting?" Li Huai was a little confused. What happened to this rich man?

Why don’t you enjoy all the good things and come to learn about prospecting?

Although prospecting sounds very high-end, it is actually a hard job.

I was exhausted every day, not only to the point of death, but also very nervous.

There are also times when detection is inaccurate. Sometimes it is obvious that digging a hole will prove that there is a mine behind it, but when digging deeper, it is discovered that there is no mine at all.

And sometimes it’s impossible for people not to believe in metaphysics. Li Huai once encountered a strange thing.

"Of course I have to say it, otherwise what would I do here? Although my family is quite rich and I have some status, I don't want to sit back and rest in vain. I don't know how to be an official, and I can't learn enough to study. All I can do is prospecting.

Well, if it doesn't work this time, my father will probably leave me alone." Chen Fengzhi said with a sad face.

Although he spoke firmly, Chen Fengzhi knew very well in his heart.

He also knows his current situation and his father's helplessness.

He also wanted to work hard, but he always found the wrong direction, and his efforts had no results.

I have to say, this is an embarrassing thing.

"Okay, let's talk about it, but there are still a lot of prospecting things, and I may not be able to finish them all in a short while." Li Huai said.

"It's okay. I'm going to stay here for a while anyway. As long as you're not bothered, I'll come here to treat you to dinner every day, and you'll be responsible for telling me these things." Chen Fengzhi smiled and nodded. He is not short of money.

, you can afford to come here every day, and the most important thing is, as long as you can learn something.

"Okay, then let me first talk about how we do prospecting now." Li Huai nodded and began to organize his thoughts.

Chen Fengzhi also began to prepare seriously.

Li Huai's performance that year was not very good, and he was basically at the bottom of his class.

Being able to get admitted to Luoyang Academy was entirely due to my major.

Basically no one applies for the geological exploration major. After all, it is an unpopular major and the prospects are not good.

Although you can get an official position, who wants to work in the mine every day?

Or just go to the wilderness?

It's the same years of hard work, and it's the same Luoyang Academy. Why can some people sit in the temple, but they can only run around in the wilderness?

And the future prospects are not as good as those people?

Therefore, unpopular majors exist in any era.

Li Huai's grades were not good and he didn't want to repeat his studies. After all, his family couldn't afford the expense.

So I followed the teacher's advice and applied for an unpopular major, maybe I might have a chance to get in.

So, Li Huai really passed the exam.

After four years of hard study, I became black. After graduation, I passed the imperial examination and successfully entered the Ministry of Industry.

Then he was assigned to a coal mine outside Luoyang to conduct basic detection.

"The first step in prospecting is to be serious and attentive. Many things are hidden in the dark. If you are not careful enough, you may miss a lot of important information."

"The most important thing next is to learn to look at soil and remember what various types of soil look like."

"The excavated backfill soil is different from the unexcavated soil layer. Judging from the appearance, the backfill soil is looser and slightly lighter in color."

"The soil layer that has not been dug is hard and dense. In addition to observing it with the eyes, when drilling holes, experienced masters can basically know it in their minds when they hit it with a shovel."

"The unexcavated soil layers have different depths and different colors. Things like coal mines are easier to identify. You can see them at a glance when you take them out. Unless you don't know coal.

"

"But it is not without exception. The first step is detection. After detecting that there is a mine below, it is a further step of detection."

"First, we need to continue drilling down at this location and drill a deeper hole to find out how deep the mine goes."

"We once made a joke in the exploration field. Because we had no experience, we just used the Luoyang shovel and quickly detected the coal mine about ten meters underground. We briefly explored the range and found that the area was quite large, so we

Start organizing mining."

“As a result, we worked hard to dig a large pit of ten meters. After mining to a depth of less than half a meter, there was no coal left. In other words, the coal seam in this area was less than half a meter. In order to mine these, it was necessary to cover the coal seam.

The top ten meters of soil will be dug up."

"Even if all the mined coal is sold at a high price, it won't be enough to pay for the digging."

"After this time, when doing detection later, we will first explore the depth to determine whether the mine is worth mining."

"In addition to these, there is still water underground. We can judge the underground water level by digging out coal. Although there is coal in some places and the depth is suitable, the groundwater is too rich. This kind of mine cannot be mined by force.

If we dig it out, we finally clean it up, but when we wake up the next morning, it’s full of water again.”

All in all, the current exploration can be summarized as finding it first, then looking at the scope, and then determining whether it can be mined.

According to the current technical level, underground mining is unrealistic and we don't have the capability, so we can only do open-pit mining.

Therefore, we can only choose those mines that are closer to the surface for mining.
