Mingyue of the Great Song Dynasty http://www./0_1/Chapter 57: The 800-meter mining is confirmed, and the discovery of agate with a diameter of 0.7 meters! (List of books!)

The next day, Qin Ru started mining directly from a depth of 500 meters.

With yesterday's accumulation.

At the end of one day, thirty tons of raw ore were mined.

But what made Qin Ru helpless was.

Today's mining still cannot improve the purity, and the proportion of agate is pitifully low.

It can be said that 29.6 tons of ore of thirty tons are all ordinary rocks.

Another big loss!

Late at night, Qin Ru stood on the deck.

Looking at the sea outside.

Silenced.

There is absolutely nothing wrong with the location.

This is indeed an agate vein.

However, how do we mine low-purity agate ore?

Qin Ru was silent.

"Is it because the world is different?" Qin Ru hesitated.

The news about this agate mine was obtained from Zhu Chenfan's memory.

Qin Ru closed his eyes and recalled Zhu Chenfan's record of this ore vein.

After a while, Qin Ru found the problem.

Zhu Chenfan saw this mine vein from the news.

Because the news broadcast the mine vein, a pure agate ore with a diameter of five meters was found.

Then it made international headlines.

After that, I went on several consecutive times and even found more than ten meters of pure raw ore.

Zhu Chenfan was curious at that time and then checked it online.

So?

So, without Zhu Chenfan knowing it before, how long did Canglan Mineral Company mine it? I don’t know at all?

No wonder, the agate raw ore mined by oneself is not only pitifully low in proportion, but also has very low purity.

It has reached the level of selling pounds.

"Is it a deeper place?" Qin Ru was silent.

If your guess is correct.

Then, the agate ore on the surface is not high-purity, and it may only be possible that high-purity agate ore will be available on the deeper seabed.

The next day.

Qin Ru walked into the command center.

"Stop, I announce new mining work!"

"Today, the Blue Fish Group doesn't have to go down. Ocean Group and Canglan Group. Today's goal is a depth of 800 meters. There is no need to work in the pipeline group. The length of the pipeline brought is only 600 meters. Notify the equipment group to install a storage box for Canglan No. 2 and Canglan No. 3!"

"Boss, we want to mine eight hundred meters?"

Zhang Daoyu was stunned.

Qin Ru nodded, "The purity of mined is pitifully low. If you continue to mine like this, you can only go back crying. It's better to go deeper!"

"Boss, but the pressure resistance of the ocean robot..."

Qin Ru waved his hand and said, "Job!"

Others saw that Qin Ru insisted like this.

It's hard to say anything.

I can only start working.

Canglan No. 2 and Canglan No. 3 began to install a storage box.

The transportation work is carried out by the two of them.

Having the experience of the previous two times.

Today's marine robots do not need steel cables to maintain.

Put it down directly.

Going towards today's goal, we will move forward at a depth of 800 meters.

More than 500 meters, it is already under the deep sea area.

Not to mention eight hundred meters.

The luminance of the strong light searchlight here is very low.

Fortunately, Canglan 2 and Canglan 3 are equipped with more than ten strong-light searchlights.

It can be seen clearly by barely.

"Boss, the signal is a bit unstable!" When it was diving to 700 meters.

The signal begins to become unstable.

Qin Ru frowned and said, "Driven signal enhancer, target, three hundred meters!"

"yes!"

Four devices were dropped from the ship.

It goes down to a depth of three hundred meters.

Then expand.

As a signal transit.

Strengthen signal transmission of blue unmanned submarines and marine robots.

Not only light at the bottom of the sea is a problem of no light.

More importantly, the issue of signal transmission.

This is why many submarines are difficult to detect when sailing in waters ranging from 600 to 900 meters deep.

Because the signals emitted by the submarine themselves will be disturbed by the situation at the bottom of the sea.

The signal detected from top to bottom will also be cancelled.

Especially when it is snorkeling in the deep sea of ​​more than one thousand meters, like the typhoon level.

Even if the noise itself is high, the submarine signal will be distorted, resulting in the American nuclear submarines that are six or seven hundred meters short of detecting the typhoon-class below.

This happened during the Cold War.

In the Atlantic Ocean, an American nuclear submarine collided with a British nuclear submarine, and below the two of them, there was a Soviet nuclear submarine.

This caused all three nuclear submarines to be damaged, especially the one in the United States, which was directly silent and all the people on the submarine died.

Under the deep sea, signal transmission will weaken.

If the main sonar is not activated, avoid it.

It is hard to know that there will be a submarine in front, back and above and below.

To this end, Qin Ru created a signal enhancer.

In theory, a signal enhancer can increase signal transmission by 500 meters.

However, as the water depth is deep, the signal transmission will also become weaker.

If signal transmission is provided below 800 meters and 1,000 meters, it is very barely necessary.

When one thousand meters provides signals for one thousand, one hundred meters, it is almost an interruption.

There are four signal enhancers.

The signals of marine robots and blue unmanned submarines have stabilized.

After the signal is stable, the picture becomes much clearer.

: "There is a platform there, past!" Qin Ru pointed to an area on the picture.

Canglan No. 2, who received the order, began to drive over.

This is a platform about thirty meters.

And below is the dark deep sea.
