Chapter 109 Small limestone mine


    More than 300 tons of steel.


    For Su Wu now, it is not something that can be obtained casually.


    At least a small high-temperature furnace must be smelted continuously for about ten days after starting 24 hours to produce more than 300 tons of steel.


    Just sending someone to the official shelter once can easily get it.


    There is no reason to refuse.


    The subsequent tasks of communicating with the other party were transferred to Chen Xin, who was accompanying her sister in the bedroom.


    Su Wu calculated that he should have nothing to do in the short term.


    Then I opened the log again and began to plan the next development focus.


    Currently in Su Wu''s hands.


    It has a mining cluster with excavators as the main force.


    After the cluster has built a road to the small limestone mine, it will also transfer to an open-pit mining team for collecting limestone mines there.


    And then, for cost and production space considerations.


    The relevant equipment for the production of cement will also be transported there. A miniature cement plant was formed on site.


    This is actually equivalent to opening a new base and production base directly there.


    And once everything involves production.


    Then energy is the most critical issue that cannot be avoided.


    Whether it is the operation of mining clusters or the production of cement itself, it requires a large amount of electricity, or even coal supply.


    Rely on just one electric transport vehicle.


    It is definitely not enough to maintain the uninterrupted operation of various equipment in the mine.


    "After the manufacturing is completed, the relevant equipment used for cement is produced."


    "Let''s build another electric transport vehicle, let''s make do with it first."


    For the early development of small limestone mines, it is enough to temporarily provide electricity with the thermal generators of the Lime Refuge.


    The distance is not too far anyway.


    There are two electric transport vehicles used alternately, and there is basically no problem of insufficient power.


    But in the later stage, the cement factory there was built.


    It would be a little troublesome if you make do with this.


    Su Wu needs to consider it.


    At that time, should we install two geothermal generators there or transport a thermal generator from Qingning Refuge.


    This is an option that makes him hesitate a little.


    From a security perspective.


    After all, the small limestone mine is a temporary simple stronghold mainly for mining open-pit ore.


    There are not many proven reserves.


    Once the ore is subsequently mined, it will basically no longer have any value.


    Therefore, at the beginning of construction.


    It is impossible to build it in a permanent, standard underground shelter.


    At most, one basement can be built, and a small ground bunker or a whistle tower.


    in this case.


    If you forcefully build a geothermal generator there.


    Because the cost of manufacturing and installation is huge.


    Not only does it take 10 survival points to manufacture a geothermal generator, when installed, pulling the extreme drilling machine over and laying a steam channel underground with nanomaterials, it also requires the material cost of nearly 2 survival points.


    Su Wu must face very heavy cost pressure and a long return cycle.


    In essence, this choice is a very invested gambling.


    If a thermal generator is used.


    The advantage is that the thermal generator itself is not too difficult to manufacture.


    Su Wu''s CNC machine tools and 3D printers can perfectly manufacture them.


    Once damaged, it will not be considered a damaging force for Su Wu.


    The thermal generator itself requires a lot of coal or diesel to generate electricity.


    Every day it runs, it consumes a large amount of limited fuel stock. Essentially, it is to exchange fuel for electricity.


    And fuel, or specifically coal.


    It was okay before.


    Now a cement production line is about to be built, and Su Wu then discovered that a large amount of coal is needed to be used during the cement production process.


    Even if there are more than 10,000 tons of thermal coal in the Lime Refuge.


    In the face of this level of demand, it is also likely that it is not enough.


    In Su Wu''s eyes, it would be quite luxurious and wasteful to regard coal as fuel for power generation.


    After hesitating for a while.


    After all, Su Wu could not resist the temptation to obtain free electricity income every day, so he chose to build two geothermal generators there.


    "Go a little bit."


    "As long as you survive the early stage, you will recover the cost. The subsequent ones will be considered pure profit."


    No mistakes, one song, one content, one in 6, one book, one bar, one reading!


    Once a geothermal generator is built, it will benefit permanently.


    Although it still needs to be questioned how long this permanence will last under the threat of natural disasters. But it''s still worth looking forward to.


    Even if it is indeed very expensive for Su Wu today.


    The 10-point survival points are comparable to a universal engineering robot.


    Su Wu has only built three engineering robots so far.


    And at the same time.


    Now that you have this choice.


    Then, more attention must be paid to the safety of small limestone mines.


    The geothermal generator will inevitably be installed in the basement under the small bunker.


    to ensure that it can withstand most conventional harsh environments.


    The bunkers must also be equipped with certain weapons to drive away some human robbers who may wander.


    Don''t look at the harsh external environment now.


    But as long as you wear protective clothing and drive a vehicle, you can still move outside.


    Then there will never be a lack of such a person.


    Then, an adequate warning and monitoring network must be set up near the mine.


    and reserve an emergency evacuation plan.


    Once an irresistible disaster may sweep over. Then try to disassemble the geothermal generator at the fastest speed and withdraw it to the ruins of the farmyard.


    "You can give up anything else."


    “But geothermal generators.”


    "If you can rescue it, try to save it."


    This is Su Wu’s expectation for the final emergency evacuation plan.


    The development route for small limestone mines was determined.


    Su Wu turned to look at the manufacturing list to be manufactured in the manufacturing center.


    In addition to the two transport vehicles currently being manufactured.


    Ranked second is a series of related equipment for the production of cement, followed by electric transport vehicles, remaining unmanufactured vehicles in the transportation cluster, and two geothermal generators at the sentry tower base.


    The task is full.


    It is enough to allow the manufacturing center to run at full capacity for three to five days.


    Su Wu thought about it.


    The manufacturing plan, which is ranked 4th, continue to move to the end.


    The number of geothermal generators manufactured was then increased from two to four.


    Anyway.


    Although the original ore type transport vehicle and two new transport vehicles have not reached the full capacity of the transportation cluster in terms of quantity.


    But it’s not that it can’t be used, at worst, you can go back and forth a few more trips.


    Once the geothermal generator is completed, it will bring continuous benefits in a long and steady stream of water.


    With the premise that you have made up your mind to build, of course, the faster you make the better.
