Three days later.

Wu Gang saw the mass spectrometry test report fed back by the exploration team, and finally figured out what was going on underground in Area 7.

Magnetite components were detected in the cores of three of the drill sites, and this was not pure magnetite, but magnetite containing titanium vanadium.

Molybdenum and rhenium have also been found.

He was not new to geology and mining, so he quickly reported the matter to headquarters.

The discovery of iron ore is secondary, and the associated titanium, vanadium, molybdenum, and rhenium associated with iron ore is an important discovery in this exploration.

It was less than two days.

Hundreds of professional geological exploration and mining professionals secretly appeared in the seventh area of the Longerang Mountain Space Base.

Weng Xuehai, a mineralogist who led the team, after on-site exploration, set 12 drill points again according to the surrounding terrain and mountain trends.

Wu Gang is very concerned about this exploration: "Dr. Weng, what do you think is the potential of this mining area, and will it affect the construction of the space base?" ”

"Preliminarily, the three mineral drill sites, the reservoirs are between 450 ~ 570 meters, the thickness of the ore layer is about 60 ~ 70 meters, the area is about 500,000 square meters, and the iron ore in this area alone is about 150 million tons."

"So much?"

"It's just that the grade is a little lower, and the grade of the sample at three points is only about 34%, which is barely an ordinary iron ore! And the burial location is too deep. Weng Xuehai said helplessly.

Another mining engineer, Ba Kang, shook his head with a smile: "Dr. Weng, you don't have to worry about this, the company has the technology to solve the mining and beneficiation problems in ultra-deep formations." ”

Weng Xuehai also seemed to have heard some inside information: "Is it the biological erosion technology and fluid boiling extraction technology that you experimented with a while ago?" ”

"Yes." Bacon nodded.

He is the engineer who led the test of the technology.

Weng Xuehai glanced at the topographic map: "If you want to use your new technology, then you must use inclined wells, with the surrounding terrain, it is estimated that the flat land here is a little insufficient." ”

Hearing this, Wu Gang already knew the other party's subtext.

That is to let the space base adjust the plan as soon as possible, after all, iron ore can not be mined, but those rare metals must be mined.

He said directly to the two of them: "I will adjust the layout of the base as soon as possible to make enough space for mining." ”

But Ba Kang on the side shook his head: "Chief Wu Base, don't adjust it for the time being, you do other work first, we need to explore the general distribution area of the ore layer, so that you don't have to adjust it when you get it." ”

The main reason why he stopped Wu Gang was because the new mining technology had a drawback, that is, it was easy to form large cavities in the ground, which then led to the collapse of the ground.

This requires that there should be no buildings within a kilometer or two above and around the mine to avoid being affected.

At the same time, this is why new mining technologies can only use inclined shafts instead of vertical shafts.

This is to avoid the mining site being built directly above the ore layer.

Wu Gang frowned: "Engineer Bakang, will this kind of large-scale mining affect the launch site?" ”

Bakang looked at the map: "Judging from the current trend of ore veins, only a part of the seven areas has ore veins, and near the launch site, no ore layers have been found, and the straight-line distance between the two places is more than 3.6 kilometers, so the problem is not big, and the scale can be controlled when the time comes." ”

This is one of the advantages of modern mining technologies.

Traditional underground mining technology requires not only the excavation of the mine tunnel, but also the exhaust ventilation and drainage, especially the ultra-deep ore veins, which must be very well placed.

Mining drainage can cause a serious problem, which is that the level of surrounding groundwater will be affected.

In severe cases, it may even cause the surrounding ground to subside.

The new mining technology does not require miners to go down, but through biological erosion of the formation, turning the formation into fine particulate matter, and then injecting water and air to turn the formation into a slurry fluid, and then using a sludge pumping equipment to pump the sludge from the formation.

During this pumping process, water is injected into the mining formation on the other side to maintain the water level balance of the formation.

Of course, there is another disadvantage to this type of mining.

That is, in the karst landform, it is necessary to pay attention to underground rivers and karst caves to avoid the inability of genetically modified bacteria to accurately corrode the mining formation.

However, in ultra-deep veins, the strata are basically relatively dense rock layers due to the weight of the years, and the underground leakage problem is not too serious.

In particular, the newly discovered vanadium titanomagnetite of Longerang Mountain this time has quite dense underground strata.

Homo sapiens developed ultra-deep mining technology, but it is also caused by the environment.

If Homo sapiens had an open-pit iron ore mine like Australia, who would mine ultra-deep veins, and it is not that there are no too prominent metal mines in the four control areas at present.

Therefore, the only way to do this is to use bio-accumulation techniques to extract some of the resources needed from the ocean.

On the other hand, it is necessary to dig deeper into the local mineral potential.

At present, for non-precious metals and rare metals around the world, in fact, only open-pit mines and shallow ores are mined.

Especially in areas outside of China, ore veins below 500 meters underground are usually not mined, mainly because the mining cost is too high and there is no economic cost-effectiveness.

And in Southeast Asia, not to mention 500 meters, even below 100 meters underground is rare.

Honsavady's mining technology can only mine the most superficial bonanza throughout Southeast Asia.

Therefore, the mining of deep mines has become another means for Homo sapiens to achieve resource self-sufficiency.

Don't look at the fact that no large ore has been found in the surface and shallow layers, but as long as you dig down, there must be many deep veins and ultra-deep veins that have not been discovered by humans.

And even if the technology is strong enough, there are a lot of rare metals and gold and the like, in the mantle and core.

The premise is that it can be mined.

The resources of the mantle and the core of the earth, Homo sapiens do not dare to think about it for the time being, but the strata between the surface and 10,000 meters underground, Homo sapiens are very thoughtful.

At least with the new mining technology, there is no big problem in mining veins two or three kilometers underground, and the mining cost is not too high.

There are two main problems restricting the promotion of new mining technologies.

One is the issue of confidentiality.

The other is exploration, after all, the cost of drilling a formation composition analysis well will increase with the increase of drilling depth.

There is no way to solve the first problem for the time being, after all, if Homo sapiens does not reach the top for a day, these technologies must be kept secret.

But the second problem has recently been resolved.

The key to solving this problem is still in bioerosion technology.

The specific operation is also very simple, directly use a very slender super-hard thimble, through the explosive fire, directly insert into the formation, form a slender channel, and then inject a certain amount of erosion bacteria into the microchannel.

This technology can drill very large diameter wells, even ultra-deep wells, with this technology can easily dig to a depth of two or three thousand meters, and the cost is very low.

On the side of the space base, the technology has not yet had time to be updated, and the geological and mineral exploration team has now used this new technology.

In addition, this technology can also be used with the green umbrella system, which does not require the import of large-scale drilling equipment, and can open ultra-deep wells and super-large wells.

After all, large-scale drilling equipment has a certain technical content, large-scale import is not cost-effective, and it is easy to be analyzed by the outside world in large-scale mining or oil extraction.
