Doomsday I Have a Super Survival System

　　 Of course An Kai didn't know what happened in the underground facility in the river bank area. He is now having a headache for one thing.

　　 That is which kind of mineral should be chosen for one's mine, as its mining object.

　　 Mine can automatically find all the veins within a radius of 100 kilometers and display them on the console. If it is an existing vein, the mining is the simplest and the output is also very large. But if you want to mine the minerals that are not available here, the difficulty will be greatly increased. According to the scattered reserves in the earth, the difficulty of mining and the output are also different. Fortunately, if there are no mineral veins in the local area, then the mining mode is the out-of-the-air collection mode mentioned before. Although the output is indeed very low, it is better than none.

　　 In local terms, the largest output of ore is actually aluminum ore.

　　Aluminum is a metal used in the aerospace industry with a large amount, and the construction and automobile industries also use a lot, but in the system, the demand for aluminum is not very large, and of course it is not useless.

　　 As far as Ankai can be manufactured or constructed through the system, the metal such as aluminum has several uses.

　　First of all, aluminum has a low density, so it is relatively soft, but it can be made into various aluminum alloys, such as duralumin, super-duralumin, rust-proof aluminum, cast aluminum, etc. These aluminum alloys are widely used in manufacturing industries such as airplanes, automobiles, trains, and ships. In addition, space rockets, space shuttles, and satellites also use large amounts of aluminum and its aluminum alloys. In the system vehicles, there are aircraft, cars, and ships. As for the aerospace field, he doesn't know if there will be any in the future, but only the former, the importance of aluminum is enough.

Secondly, the conductivity of aluminum is second only to silver, copper and gold. Although its conductivity is only 2/3 of copper, its density is only 1/3 of copper. Therefore, the quality of aluminum wire is only copper wire for the same amount of electricity. Half of it. The oxide film on the aluminum surface not only has the ability to resist corrosion, but also has a certain degree of insulation. Therefore, the electrical system of the shelter also has a demand for aluminum. .

　　 Again, aluminum is a good conductor of heat, and it is a good choice to make kitchenware.

　　 In addition, aluminum has good ductility and can be made into aluminum foil, which can be used for food processing and packaging.

　　The surface of aluminum has a dense oxide protective film, which is not easy to be corroded, so it can also be used to manufacture chemical reactors, medical equipment, refrigeration equipment, etc., all of which are within the manufacturing range of the system.

　　Aluminum powder has a silver-white luster and can be used to make coatings. It can be applied to ironware to protect the iron ride from corrosion and be beautiful.

　　 In addition, aluminum burning in oxygen can emit a lot of heat and dazzling light, and can be used to make explosive mixtures, such as ammonium aluminum explosives, combustion mixtures, and lighting mixtures. It is a frequent visitor to the preparation of system weapons.

　　 Finally, aluminum has sound-absorbing properties and good acoustics, so aluminum is also used in the ceilings of broadcast rooms and modern large-scale buildings. When the temperature of aluminum is low, its strength increases without brittleness, so it is an ideal material for low-temperature equipment, such as cold storage, freezer, etc.

　　 In short, the role of aluminum is very large. It cannot be said that it is indispensable to Ankai's shelter, but it is better than nothing.

　　 is just the amount of this thing, which is definitely not as good as iron and copper, so if there are these two minerals, he will be very happy.

　　 It's a pity that apart from aluminum, there are no other patches of mineral veins within a hundred kilometers of this land under my feet, which makes people very depressing.

　　 From this perspective, the address of the shelter he chose is really average.

　　 But there is no way, who told him to not put down the mine earlier.

　　Although this place is not too good from a mineral point of view, other than that, this shelter is quite good.

　　 First of all, in terms of distance, the straight line from the city to the river bank is only more than ten kilometers, which can be said to be very close. It can be said that it is very convenient to collect materials or supplies.

　　Secondly, this place is a small canyon, the terrain is sunken, there is water resources not much deep underground, to ensure that they will not lack water to drink here.

　　 The third point is that the main entrance of the sanctuary is in the shade of the mountain, and the location of the nuclear explosion is just on the other side. The mountain becomes the best barrier to stop the shock wave of the nuclear explosion.

　　 In short, no matter from which point of view, the location of the shelter is actually very good. There are not enough minerals, so we can only use stupid methods.

　　 In consideration of the reality that the number of various equipment in the shelter is not enough, and the resources are not rich enough, Ankai is not willing to waste resources in vain, so the mining direction of the mine can only choose aluminum ore.

　　 After making a selection, press the mining switch.

　　 In the next second, a drill bit penetrated the ground and entered the ground.

　　 Like the drill bit of the water purifier, the drill bit of the mine drilling rig also has monitoring equipment, and Ankai can determine the position of the drill bit through the screen.

The drill bit first descended in a straight line. After descending for about a few hundred meters, it paused for a while, and then moved laterally~www.wuxiahere.com~ bypassing the underground river, and then moved forward about a kilometer, then paused again. , And then slanted hundreds of meters in the countryside, and finally stopped slowly.

　　 Immediately afterwards, the drill bit rotated on the spot while continuously expanding. Deep in the ground, it first created a circular space with a radius of about one meter.

　　 Then, like a worm, a smaller drill bit emerged from the fixed drill bit. As soon as the drill came out, it pierced directly somewhere, and began to spin frantically at a higher speed.

Where 　　 passed, the surrounding rocks were shattered one after another, and then caught by a device similar to a conveyor belt and a vacuum cleaner, and finally sent back to the shelter far and wide.

　　 This process lasted a total of about half an hour, and then the gold mining rig next to An Kai opened a hole, and blocks of aluminum ore were spit out by the machine.

　　 There is a box below, which is responsible for storing these ore. After collecting a box, it can be transported away immediately, and then the new box can be placed here.

The subsequent smelting is very simple. Electric furnaces and fire furnaces are also acceptable. In short, compared with open-air operations or manual well drilling, this kind of fully automatic drilling is extremely efficient. Leave it alone. A large amount of ore can be collected in a day, too much to use up.

Of course, An Kai couldn’t really just leave the machine on like this. After staying next to the drilling machine for more than an hour, he got more than four boxes of ore. Considering his limited amount, he immediately put the machine on. Shut it down. For the time being, these are enough, and we'll talk about it later when we need it.

　　 And he needs to build more drilling machines. After all, the amount of aluminum is not that big, he needs more iron and copper.
