He picked up a core, looked carefully, turned around and asked, "What's going on with these cores?"

"How do we know? Maybe the drilling technology that was drilled more than ten years ago failed to meet the standards and was treated with waste holes." A technician replied in a stiff tone.

"This makes sense."

Xu Xin nodded, threw down the core, and continued to move forward in a straight line along the exploration line.

If you want to find the direction of the exploration line, you must always stare at the instructions of the compass, look at the other side, and often have no way to pay attention to your feet. You fell into the ditch twice in a row, making the three people following you laugh so happily.

When he fell into the ditch for the third time, Xu Xin's arm almost broke because his arm hit the hard stone.

I turned over and got up and saw that the pile of stones under me were not ordinary stones at all, but a pile of rock cores that were randomly discarded!

The way to discard this pile of cores is even more casual than the cores I encountered before, and I am too lazy to bury them.

"What's going on with these cores?" Xu Xin looked up and asked the technician who was laughing standing on the small ditch.

"This...maybe it's a useless hole."

"Okay, let's keep moving forward."

Xu Xin climbed out of the ditches, crossed mountains and ridges, and continued to move forward.

I found another core discarded point behind.

Combined with the automatically generated sectional diagram of the system, he figured it out.

All of these abandoned drilled cores have no ore.

When we arrived at the place where we saw the mine, we built large and beautiful sealing signs with cement at the drilling location.

Moreover, these are mineral holes, and the distance between drilling and drilling is not large.

There is also a reason for drilling arrangement, sometimes the distance is five or six hundred meters, and sometimes the distance is two hundred meters.

So casual?

In the report, the reason why the drilling distances are so different is actually an explanation of the situation.

The elevation changes in some places, and the hillside is steep, so it is not suitable for drilling, so the hole is moved.

No wonder the expert group failed to pass the acceptance.

There are too many drilling holes to be moved, right?

In fact, it is not just a hole that is moved at all, but a histogram of holes that are not visible is not drilled, and presented to the data results.

This is simply a matter of trying to cover up the truth and secretly visiting Chen Cang!

Naked mineral search and fraud!

After Xu Xin walked down, he saw the shocking means of these survey work.

Because the stratigraphic analysis horizon depth is set at 400 meters, the energy point consumption increases exponentially compared to the 200 meters depth.

He only has 60 energy balance and travels through the entire mining area for about four kilometers.

A sectional view is automatically drawn in the horizon.

On the sectional view, the ore layer is not continuous, but is irregular circles, large or small, deep or shallow, scattered everywhere.

This is a typical lenticular ore body.

The energy has been completely exhausted.

They are at the other end of the mining area far away from the command center.

Xu Xin called Qian Pangqing and sent a car over, and had to wait for a while.

He sat on the side of the road, and his skin was exposed with spikes, and his clothes and hair were covered with dense Xanthium fruits.

Judging from the current situation, they can completely overturn all their understanding of this mine.

The mining plan they designed based on the information from twelve years ago is all shit!

If the current plan is invested in the cost, mining the mine.

There is only a waste of hundreds of millions of cash, but at least it is definitely impossible to recover the cost from the mine.

It was too late to find something was wrong after large-scale mining.

Xu Xin took out his cell phone and called his father.

"You run back to the city by yourself, don't say hello, do you have the face to call me?" Xu Hengqiang's voice suppressed his anger.

Xu Xin didn't want to explain, so he said directly: "I found some problems in the Yantugou bauxite mine."

"What are you doing there? I'm so full?"

"I'll tell you two problems I found. I really don't understand. I hope you can give me some reference."

"Tell me, look."

"First point, the Yantugou bauxite deposit is not a sedimentary deposit, but a lenticular deposit..."

"You don't need to say this, I guessed it more than ten years ago!

Our Heijin Province has rich bauxite reserves and is one of the best in the country. Bauxite is mainly distributed in the central region, especially in our Xingfu City. There are many medium-sized bauxite deposits and small deposits, all of which are lens-shaped deposits.

It can be said arbitrarily that large sedimentary bauxite deposits are almost impossible in this land of Xingfu City.

It is mainly determined by the mineralization conditions, and I can't explain it clearly for a while. I will have a good chat with you when I have time."

Xu Xin listened to this and received teachings.

This is a rule summarized by decades of experience.

Xu Xin continued: "I walked along an exploration line and found that at least three drilling cores were abandoned. No ore layers were found in these abandoned cores. There is a rule that the cores of the ore are well preserved, and all the cores of the ore are abandoned."

"I haven't seen it at the Yantugou Bauxite Mine, so the specific situation is not clear.

Only the information of the ore holes is retained, but all the ore holes are destroyed, which creates the illusion of continuous ore layers, thus drawing the conclusion of the sedimentary ore deposit. That's what it is."

"Yes, I can't figure out how the project was accepted later?"

"The acceptance expert group has changed all the people before they pass the acceptance. No one knows what happened at the beginning, and we can't care about those problems."

"The mines here have entered the mining operation stage, and they are mined according to the scale of large mines, with huge investment!"

"When digging down, it was found that the deposit was discontinuous. What was dug out was not bauxite, but valuable soil and stones. I could only admit compensation. This kind of thing is not common in the mineral industry."

"Dad, you're so cruel to say that. Qian Pangqing is my classmate's father after all, so I want to help.

Not to mention any help, it is also good to remind you and stop losses in time.

Do you think there is any good solution?”

"This issue is very complicated. It depends on the ore-seeking situation of underground lens-shaped bauxite deposits and whether the enrichment level is suitable for industrial mining.

The mining area is relatively large, and the lenticular ore bodies are distributed scattered. It is very difficult to safely understand the distribution and scale of the ore body.

As the surveyor, if you encounter this situation, just report to Party A truthfully. It is not suitable to continue the survey."

"What if I have to verify it?" Xu Xin asked hurriedly.

"According to geological methods, the drilling and the grid density is reduced, and a hole is spaced between 50 meters and 100 meters, which can definitely make the scattered ore bodies clearly touch.

Of course, the total number of drilling holes in this method is probably close to 100,000 meters, and the investment is over 100 million.

After truly understanding the ore body situation, adding mining costs and taxes may not necessarily make a profit."

The truth is indeed the case.

Xu Xin scratched his head and smiled and said, "Is there any simple and easy way?"

"Physical Exploration, isn't this what you major in college?"

"Uh, yes, but I only learned basic theories. Dad, tell me directly, if it was your decision, which method would you use?"

"Current geophysical surveying is nothing more than heavy magneto-electric shock. Earthquake exploration has developed rapidly in recent years and has made great progress in deep exploration. However, in terms of finding solid ore, the earthquake method seems to be inappropriate.

Magnetic ore exploration should not be suitable there. The bottom plate of the bauxite layer should have a layer of iron ore, which has a great impact on the determination of the bauxite body.

Electrical measurement is very suitable. Measuring the resistivity difference between lithologies can roughly enclose the size and position of the ore body. However, this method is very costly and time-consuming. This method is the most mature in technology.

If you want to save money and time, use relative gravity to measure it. A measurement point only takes a few minutes. However, this method has a huge error.

Generally speaking, in addition to earthquake measurements, the other three measurements are greatly affected by various factors, and the measurement error is also very large. The explanations are diverse and can only be used as reference."

"Okay, I get it."

"Learn more and read more, think about everything in your mind, how can you improve?" Xu Hengqiang did not forget to teach a lesson.
