With the increase in manpower, the scale of the iron ore was almost detected in just three days.

Then they urgently borrowed a batch of equipment from the field exploration team to carry out detailed detection of underground iron ore.

Half a month later, a report about the discovery of iron ore in a coal mine outside Luoyang appeared on Wang Buxu's desk.

This is not a final report, but a summary of what has been detected so far.

Due to technical reasons, no more information can be detected in the short term.

And every time you probe down half a meter, you have to pay a huge price.

The reason is that the spliced ​​Luoyang shovel is not enough to support such intense work.

It doesn't matter if it's one meter, two meters, or three or five meters.

However, he had to pick up a length of 20 to 30 meters in one go, and he had to hit it with a sledgehammer to drill down. As the number of uses increased, the shovel handle irreversibly bent.

With this length, once bending occurs, the stress point at the bottom of the entire Luoyang shovel will change.

At this time, no matter how much force is exerted on the top, it will not have much effect on the bottom. Instead, the shovel handle will become more and more bent until it gets stuck inside, making it difficult to even take it out.

Therefore, the report that appeared in Wang Buxu's hands found that the deepest detection was only twenty meters.

And just at this point, the rest of the depths are generally between ten and fifteen meters.

Although it is not complete, this report can basically prove a fact.

In the coal mines on the outskirts of Luoyang, the associated mines of iron ore have basically been mined.

As for the size of the iron mine, the area that has been proven is six hundred paces long and more than nine hundred paces wide.

What's not sure is how deep it is.

But no matter how deep the depth is, the currently detected depth of fifteen meters is full of iron ore. This alone is enough for them to prepare for mining.

This matter is not a big deal to Wang Buxu.

He doesn't even need to go through and approve it, the Ministry of Industry will take care of it themselves.

Whether it should be mined or not is actually not a difficult question.

Iron ore is in the coal mine, so even if it is to mine coal, this iron must be mined.

The worst case scenario is to take it to Luoyang, where the iron ore will be smelted directly and then used in experiments by the Academy of Sciences.

What Wang Buxu needs is the right to know. I need to know this matter.

However, through this incident, Wang Buxu once again realized the Han Dynasty's backwardness and helplessness in exploration methods.

If it's too deep, you can't hit it, and if it's too shallow, it's useless.

Real exploration is to get to the bottom and clearly know how much reserves the mine has and whether it is worth mining.

The current technical means are not good enough. Even if some mines are detected, they do not have the strength to mine them.

Currently, the only ones that can be mined are those mines relatively close to the surface.

This is the so-called open pit mine, if the reserves cannot be proven, or sufficient mining value cannot be ensured.

No one is willing to bear the consequences of hasty mining.

What if they managed to break through numerous obstacles and finally find a mine located twenty meters underground, but in the end they could only reach a depth of twenty-five meters.

In the end, after all the hard work, the overburden was dug out, and the mining was over before the mining was done?

Therefore, in order to avoid such embarrassing situations from happening one after another.

The imperial court must speed up the upgrading of exploration equipment.

Just relying on a Luoyang shovel is not enough.

The Luoyang shovel can precisely guide and position mining operations.

Another function is to detect in advance whether there are underground rivers through the exploration of the Luoyang shovel during the operation, thereby avoiding the digging of underground rivers and the occurrence of water seepage accidents.

Although water seepage in open-pit mines is not terrible, it will not cause too much loss of life.

However, once water seepage occurs, it will still have a great impact on mining.

Therefore, if we just talk about exploration, the best way is to get an exploration vehicle.

The thick ones cannot be removed, and the thin ones cannot be manipulated.

Manpower has always been limited in the face of nature. Forced exploration would be too labor intensive and too difficult.

If machines are used to replace manpower, there will be no such problems.

Even spliced ​​probe tubes can be drilled because the machine can drive thicker tubes.

Thick means it is durable and can hit deeper places.

So, Wang Buxu waved his hand and approved the note directly.

"Give this to Wang Ji!" Wang Buxu casually handed the note to Secretary Lang.

The vehicle side is basically done, but some details still need to be adjusted.

In addition, the endurance is not enough and there are some problems with power output.

These need to be adjusted slowly.

Wang is not hungry and doesn't want to get started in a hazy manner. In the future, the streets will be full of broken down vehicles waiting for repairs.

Now that small drilling rigs have been made, it shouldn’t be a problem to make a slightly larger rotary drilling rig, right?

However, technology is like this. When you break through one technology, other technologies will soon follow.

These related technologies are basically derived based on the same principle, and only need to make some changes in details.

For example, a forklift and an excavator may look different, but in fact they have similar principles.

It's nothing more than one upward move and one downward move, changing the layout and refining the design, and it's basically done.

"Your Majesty, Zhang Shangshu of the Ministry of Revenue is asking for an audience outside the palace..." Another secretary came in cautiously to report.

Hearing that Zhang Cang was here again, Wang Buxian subconsciously scratched his head.

What he hates to see the most now is Zhang Cang.

I even felt like I wanted to kill him.

This is simply a dog-skin plaster. If you don't care about anything every day, he will have to bother you for a while.

And the purpose of coming every time is the same.

But, it’s not okay if I don’t see you.

Therefore, Wang Buxu had no choice but to wave his hand to let him in.

Zhang Cang walked in with cheerful steps and a serious and anxious face, holding a thick piece of information in his hand.

"Your Majesty, I think it is enough to place a maximum of 100,000 garrison troops within the Han Dynasty. You see, I have made a detailed planning plan..." Zhang Cang came up and placed the information in his hand in front of Wang Buxu.

Compared with just relying on a word before, this time the preparations were obviously more meticulous, and even the garrison plan was worked out.

"There are no enemies in the north. It is enough to deploy 100,000 cavalry to patrol the grassland. There is no problem with 100,000 people in the Western Region in the west. 150,000 people in the Nanjun military camp are also okay. Although 100,000 people in the Shujun military camp is a bit too much, but consider

Depending on the terrain and environment, it’s not unacceptable.”

"Then the remaining places are the real interior of the Han Dynasty. There are enough military protections around it, so there is no need to deploy heavy troops inside. We can deploy three to five thousand people according to the size of each county, and then in
Chapter completed!
