Chapter 1692 has been tempered for a thousand years

"Whew-"

Throughout the mountain, the sound of air drills and drilling boreholes was heard incessantly. Pen? Interesting? Pavilion wWw. ｂiquge。 infoA professional engineer is holding a wind drill driven by gasoline explosive power, drilling holes in the rock.

After all the designated blast holes were drilled, the sappers in charge of drilling quickly evacuated the hill with the wind drill rig.

Subsequently, the blasters began to bury explosives in the holes.

When everything was ready, everyone evacuated from the mountain, and as the on-site engineers counted down the seconds, the entire mountain suddenly heard the sound of a landslide and tsunami.

"Boom-"

The ground trembled violently, and the entire mountain seemed to collapse, and huge dust and smoke rose to the sky.

Half an hour later, the smoke slowly cleared, and as the whole mountain revealed its true face, there was a loud cheer from up and down the mountain.

"Out of the coal—"

I don't know who shouted, and the long voices in the mountains and forests reverberated back and forth, and everyone had a bright smile on their faces.

An Yi watched the entire process of opening the mountain with a telescope at the bottom of the mountain, and was proud of the sapper team that had such excellent blasting skills.

After the blasting was completed, the hill that had withered and yellowed after the trees were removed suddenly turned black as the surface soil layer was blasted, and the whole mountain had become a coal mountain after the rock and soil were peeled off.

On the road leading to the coal mountain, bulldozers and excavators drove to the top of the mountain, and trucks lined up in long queues, waiting neatly to load coal.

The bulldozer pushes the blasted coal together, and the excavator's huge grab arm reaches out to the coal pile, and after closing it, it takes a large amount of coal, turns the grab arm, and puts it on top of the truck at the head, and the grab arm is wide open, and the black coal falls into the car. After a few grabbings, a four-ton truck was filled and slowly drove down the mountain.

The whole process is smooth, and the speed of coal production is far faster than people imagine.

Professor Wang Zijun, a geological expert of the Syrian Research Institute and the chief engineer in charge of the blasting, introduced to An Yi with a smile:

"Chairman, this is really a treasure of feng shui, who would have thought that in the Tom River valley in southeastern Western Siberia, between the Kuznetsk Mountains and the Salaire Mountains, there would be such a large coal field? With it, not only will there be no need to worry about coal in Central Asia, Mongolia and the Far East in the future, but if there is an outlet to the sea in the south, the coal of the whole of South China can be satisfied. ”

I have long heard Hu Jialin and Huang Zhi introduce that dozens of mountains near and far are such big coal mountains, An Yi is figuring out how many reserves there are, and when he heard Wang Zijun say this, he asked curiously: "Professor Wang, how big is this coalfield, and how considerable are the reserves?" ”

Wang Zijun's face was excited: "This coalfield is trending from northwest to southeast, with a length of about 300 kilometers, a width of about 100 kilometers, and an area of about 26,700 square kilometers.

"This coal area is characterized by thick coal seams and excellent coal quality, and the geological reserves of coal have reached more than 600 billion tons at a depth of only 1,800 meters, of which the proven reserves of coking coal are as high as more than 33 billion tons.

"The coal quality of this coalfield is excellent, the sulfur content is less than 1 percent, and there are many coal seams, a total of 120 overlapping layers, and most of the coal is shallow in the mine, which is very suitable for large-scale open-pit mining, and the production cost is very low. According to our calculations, the cost is only half of the Donbas coalfield in the Soviet Union, and one-third of the Pechora coalfield, which is more than our Liupanshui coal mine. ”

Seeing An Yi's stunned look, Hu Jialin smiled heartily, pulled him aside, and said in a low voice:

"Xiao Yi, now you understand why I don't agree with you to set up a nuclear base in Central Asia, right? Discovered in the early eighteenth century, mined in the sixties of the last century, and produced 1.3 million tons of coal a year before the October Revolution, and began to be developed on a large scale during the first five-year plan of the Soviet Union, most of which was supplied to the western regions of the Soviet Union. On the basis of the coal field, a number of industrial systems such as metallurgy, machinery, electric power, chemistry, and building materials have been developed, forming a comprehensive heavy industry base, and this time we have completely taken over from the Japanese army.

"This area of the railway line crisscrossed, along the two banks of the Tom River, there are more than 60 small and medium-sized industrial and mining towns, all major towns have machinery manufacturing and metal processing industry, focusing on the production of heavy machinery. As long as we occupy this area steadily, there is too much energy to be used up, and if we add a nuclear base by our side, we won't even be able to sleep safely, it's just a toss! By the way, Xiao Yi, after I explained to you last time, has the new site of the nuclear base been chosen? ”

An Yi nodded: "It has been determined, at present, the Gulf of Siam has become the inland sea of our South China, and the security has been effectively guaranteed, and the nuclear base is ready to be built in Dara, north of Kampong Son Bay, where it is a plain dam surrounded by mountains, surrounded by primeval jungle, and a large river at the southern foot of the Cardamom Mountains flows through Deira and connects with Kampong Son Bay, and if the river is cleaned up a little, a 500-ton steamer can sail directly from the sea to Deira, which is 25 kilometers inland."

"At the same time as the construction of a large nuclear base, high-energy-consuming electromagnetic, electronic, metallurgical and other research laboratories will also be built in the surrounding area of the base, the entire construction period is expected to be three to four years, in between, nuclear research will not be interrupted, the research base in Laizhou will use large-scale computers to analyze and calculate nuclear fission, collate and collect data, and relevant researchers will conduct subcritical test explosion tests to gain experience in manufacturing nuclear weapons."

"Test explosion!?"

Hu Jialin was taken aback: "So, the kind of big killing weapon you said has been made by the laboratory?" ”

"Nope!"

An Yi smiled and categorically denied: "Where is it so fast, the so-called subcritical test explosion is a test explosion that will not have a nuclear explosion." To put it simply, it is to remove the uranium or plutonium core of a trial-made nuclear bomb and replace it with a steel block of the same shape for a test explosion. In other words, it is a test explosion to test the effect of a nuclear trigger unit composed of a swarm of explosives.

"When the number of critical test explosions reaches a certain level, the relevant data collection is sufficient, and there is no need for actual nuclear tests, as long as the subcritical test explosion is carried out, the design of the nuclear bomb can be slowly improved. The essence of the subcritical test explosion is only the detonation of explosives, which is the same as the test explosion of artillery shells and bombs, so there are only tens or hundreds of kilograms of explosives exploding, so they cannot be detected, or it cannot be distinguished from ordinary bomb test explosions.

"In fact, the implosion compression device is the most difficult step in the design of the mass killer. One of the difficulties is how to detonate the explosives at the same time or at a predetermined time, and the error accuracy must reach a few tenths of a microsecond; The second is how to determine the shape of the explosive block so that the energy can be evenly squeezed into the expected blast center according to demand. These two conditions will determine whether the mass killing weapon can be effectively detonated, whether it can fully utilize the nuclear reaction substance, and whether it can fully exert its power.

"The point is that this key technology has nothing to do with nuclear materials, and can be carried out even without ptonium or uranium cores, so it can be divided into another group and carried out at the same time as the refining of nuclear materials, so as to shorten the development time of the overall program. On the other hand, if the detonation time can be precisely controlled, you can make a large killer weapon with adjustable power, such as adjusting the detonation time of some of the explosive blocks, which can change the final compression ratio and compression shape, thereby reducing the explosion power. ”

Hu Jialin was dumbfounded when he heard this, An Yi smiled and shook his head: "These introductions are very jerky and difficult to understand, right?" I also forcibly memorized it after listening to the explanations of those nuclear physics experts. However, these knowledge are somewhat close to the explosion theory of our sappers, and the more you understand and think about it, you can slowly digest it.

"Beard, let me give you an example, the theoretical power limit of a big killer weapon is affected by the nuclear charge and the original design, and cannot be increased, but it can be reduced. Therefore, you can take a 10,000-ton big killer weapon, by precisely adjusting the detonation time of each explosive block and reducing its power, you can form a multi-level choice of 10,000 tons, 8,000 tons, 5,000 tons, 3,000 tons, and 1,000 tons, which will have a great tactical use at some point. ”

"Is it fruitful?"

Hu Jialin asked with interest.

An Yi smiled: "If there are no results, I won't tell you." At the same time as the establishment of the Institute of Nuclear Physics, the subcritical explosion test team was established, and more than 100 engineers and military experts were transferred from the Syrian Ordnance Research Institute, and more than a dozen mathematicians and physicists who were responsible for assisting in the calculation of focused surfaces and the study of detonation physics. Their task at that time was to use lathes to process and manufacture a large number of various shapes of steel, copper, tungsten and other metals of different hardness, mainly spherical or oval, and then design, manufacture and combine into explosive blocks of various shapes and properties, focus the explosive energy, and carry out implosion compression tests on these steel balls.

The first hurdle that the team had to overcome was to design a shape and configuration of explosives that could compress a specified volume of steel balls to the smallest amount of explosives. In addition, they needed to design a variety of surfaces and focusing methods to enhance the effect. After more than a year of hard work, especially in the second quarter of this year, after the power of the Laizhou experimental base was fully guaranteed, this group of people had to carry out an average of two to three test explosion compression tests per week, and more than 100 critical test explosions have been carried out so far.

"Now, all of the people in this group are masters at designing and arranging explosives, and they claim to be able to blow up steel balls of any shape and size you specify. Of course, the experiment will continue to be carried out, and new technical experts will be trained to accumulate more experience. In the future, we have this group of experts who specialize in playing with explosives and implosion, even if highly enriched uranium and plutonium are not developed in a short time, the general design of the relevant core trigger unit can be completed in advance and keep improving. ”

Hu Jialin was dazzled and pointed to the sappers in camouflage who were inspecting the explosion point on the coal mountain: "It is estimated that compared with the officers and soldiers who bombed the mountain, the people in that group are masters who play explosives, and our soldiers can only be regarded as beginners." ”

"There is a specialization in the art industry, and you don't need such a high blasting skill to open the mountain, just enough for it!"

An Yi introduced in a low voice: "The first group of explosives experts, we have assigned a part to assist the Ordnance Research Institute in designing some special forms of ammunition, such as bazookas and rockets that are bundled with explosives jets, anti-tank grenades for combat vehicles, and some special shaped bombs, as well as cluster armor-piercing warheads for several heavy torpedoes. They were also responsible for the development of various high-powered explosives and blunt explosives for nuclear bomb triggers.

"With this group of well-trained implosion experts, coupled with a series of test explosion experiments and data collection, we are very confident that in the next five years, the volume and weight of tactical mass destruction weapons will be greatly reduced to the extreme, so that our future missiles and even artillery can launch nuclear warheads, and we will be invincible at that time."

Hu Jialin nodded with satisfaction, and just wanted to say something, when he suddenly saw Shen Fengdao walking quickly, and said with a smile: "Seeing that the madman is in a hurry, there must be something urgent!" ”
