A doctor who travels through two eras

Pingshuo Antaibao open-pit coal mine, viewing platform.

Lin Sanqi looked at the huge pit in front of him with his mouth wide open. He could no longer find words to describe the shock in his heart.

Yin Lianyi also saw this geological wonder and exclaimed:
"Wow, this is too big! If this coal pit is filled with water, it will be like a big ocean. Look at the cars in the coal pit, they are just like small ants."

After saying that, he started taking pictures non-stop with his SLR digital camera.

Yuan Lei burst into laughter after hearing this:

"Xiao Yin, you are mistaken. These trucks are really huge. If you look closely, you will know that they are very, very large. The trucks alone weigh 100 tons. Getting on a truck is like climbing up to the second floor. They can load 300 tons of coal each time. They are currently the largest trucks in the world."

After hearing this, Lin Sanqi thought to himself, my goodness, the modified truck in his space can only carry 5 tons at most, and this truck can carry 300 tons at a time. If he gets one, it will be very beneficial to his smuggling activities.

But Lin Sanqi didn't care whether the truck was big or not. He was a little anxious:

"Brother Yuan, this is not right. Didn't you say this was an open-pit coal mine? Why is the coal being mined at the bottom of this huge pit? I think to transport the coal out, large trucks have to go around the pit wall in circles. This is too troublesome."

Yin Lianyi reminded, "It's not just the big trucks. Look, Sanqi, there's a small train circling over there and climbing up from the pit."

Lin Sanqi took a closer look and became even more worried. He thought that there would be no such giant trucks in 1960. How would the coal at the bottom of the pit be transported out?

The people around laughed again. Manager Ke from the production department of Pingshuo Coal Mine said with a smile:

"Xiao Lin, when we discovered the Antaibao open-pit coal mine more than 40 years ago, it was not what you see now. At that time, there was no huge coal pit, but just a piece of flat land in the valley.

When we were mining coal seams, we just used explosives to loosen and break the coal seams, and then large trucks could transport them directly, which was very convenient.

But this coal mine has been mined for 40 years. Over the past few decades, the surface coal seams have been mined out. We have no choice but to continue digging down layer by layer. As a result, the pit has become larger and deeper, and it has formed its current scale. "

It turned out to be the case.

When Lin Sanqi heard this, he blushed and thought to himself that he was really an amateur talking nonsense.

Yin Lianyi studied economics, so she is naturally more interested in data:
"Manager Ke, what is the annual output of our Antaibao open-pit coal mine?"

Lin Sanqi was also very interested in this data and pricked up his ears.

Manager Ke knew that the two young men came here by Coaster from the superior department and their identities were not simple, so he replied politely:
"Our current annual output is just over 2000 million tons, but we are actively investing in new equipment to continue expanding production capacity and eventually reach 3000 million tons per year."

Yuan Lei also spoke at this time:

"We came here to inspect the production of the Antaibao open-pit coal mine, and secondly to re-evaluate the reserves of the coal mine. We also need to check issues such as production safety and environmental pollution."

Lin Sanqi thought to himself, I am not a superior leader, and I am not interested in your bragging and official talk.

Yuan Lei and his colleagues had their own work to do, so they left first.

Lin Sanqi and Yin Lianyi, accompanied by a young secretary from the coal mine, were free to walk around and visit as they pleased.

Lin Sanqi saw with his own eyes the current situation of the coal mine and its annual output. The most urgent question to know now is where the coal mine is located, that is, the location must be remembered.

It will be convenient for me to travel back to the 1960s and look for it later.

Remember that the best way to locate a coal mine is with longitude and latitude. As long as you have this data, you will never make a mistake.

But if Lin Sanqi went back to 1960 and told his superiors that he knew where there were coal mines in the country and asked them to go and dig, people would probably think he was a psychopath.

Or, like the hybrid technology, the valuable information he submitted was put aside, and then a meeting was held to study and discuss it, but in the end it was left unresolved. So when Lin Sanqi traveled back to 1960, the best way was to lead people to dig and find coal to prove it to everyone.

But in 1960 there were no satellites and no GPS signals, so we could only use tools such as clinometers and rangefinders to measure at multiple control points, and then calculate the longitude and latitude.

The accuracy of ground surveying is limited by the precision of the surveying tools and the skills of the operators, and is very prone to errors.

A small calculation error, even a few digits after the decimal point, may cause the location to shift directly from Shuozhou to neighboring Inner Mongolia. That would be a huge mistake.

So Lin Sanqi needs to know the original information of the Antaibao open-pit coal mine.

So after taking a lot of photos of the hills around the coal mine with his camera, he asked his secretary:
"Secretary Wu, do you know if there are any scenic spots or historical sites around our coal mine?"

In 1960, even though the historical sites and monuments were not protected, no one destroyed them, so the easiest way to find the coal mine was to locate a certain monument.

Secretary Wu was obviously a local, so he was quite familiar with the surrounding situation. He pointed to several mountains in the east and said:

"Speaking of scenic spots and historical sites, the most famous one here is the Jingde Temple on Liyang Mountain. It has a history of more than a thousand years and is still very popular."

Lin Sanqi was confused: "Wow, an ancient temple with a history of more than a thousand years? From the Tang Dynasty? It's rare, what's the origin of this temple?"

Secretary Wu introduced it with great interest:
"Hey, speaking of this Jingde Temple, it was actually the ancestral temple of Yuchi Jingde's family. He was born here. You know Yuchi Jingde, right? He was the hero of the Lingyan Pavilion of Emperor Taizong of Tang Dynasty, and later became the folk door god."

Lin Sanqi and Yin Lianyi nodded repeatedly, "I know."

"Jingde Temple is one of the few remaining Tang Dynasty buildings in China. Because it is located in the deep mountains and old forests, it has escaped the wars and disasters for more than a thousand years and has been successfully preserved to this day. Classmate Lin, Classmate Yin, do you want to visit it?"

Lin Sanqi nodded again and again: "Then I'll trouble Secretary Wu."

Secretary Wu was actually quite puzzled. He thought, you guys agreed to write a paper on coal, so why didn't you look up information or visit the coal museum first when you got there, but instead went to visit some dilapidated temple first?
I guess these are some young man and young lady from a certain family who have come out of Beijing to have fun.

Secretaries are all very good at dealing with people. They won't ask questions that they shouldn't ask. They just need to do a good job of providing service and reception.

The car drove on the winding mountain road for half a day and finally arrived at the "Jingde Temple" on the top of the mountain.

Jingde Temple is not large and is relatively well preserved. There is not a single tourist inside. Well, who would come to such a desolate place with inconvenient transportation?
No wonder it has been well preserved for more than a thousand years. Even the little soldiers who hated old things the most back then did not come. They probably couldn't climb the mountain.

Lin Sanqi took out his cell phone and started taking pictures non-stop, from the mountain gate all the way inside the temple.

Then I stood on the base of the ancient temple and took pictures of the surrounding mountains, especially the huge Antaibao coal mine at the foot of the mountain.

As long as he found the Jingde Temple in 1960, Lin Sanqi would have enough confidence to find the largest open-pit coal mine in the country.

After bidding farewell to Yuan Lei and his group who were going to continue their investigation, Lin Sanqi, after achieving his goal, took Yin Lianyi to travel to Datong next door.

Datong is a city changed by Mayor Geng. Leaders with vision and pattern can change a city or even a country. This is why the leader must be chosen well.

Of course, Lin Sanqi and Yin Lianyi spent most of their time in the hotel, and didn’t even go to the Yungang Grottoes…

After returning to Huadu, Yin Lianyi and three other young ladies from the Finance Department re-formatted and printed the information brought from the State Administration of Coal Geology.

All the data that could reveal modern information, such as dates and exploration units, were deleted, leaving only the data and parameters of coal mines across the country, and then they began to print them out one by one.

A coal mine was bound into a book of materials, and the final summary could fill up half a container. Even the printer was about to smoke. (End of this chapter)
