The strangest mine The mine mouth is built on a coastal cliff, and the cost is cut by 70 percent of the mine
In this world, there are many abandoned mines that have been converted into tourist destinations, such as Yellowstone National Park, which is rich in large quantities of black yaoshi, which was used by ancient Indians to make arrows, and in China, there is a mine in Beijing, and there is a coal mine in Tangshan. However, we would like to speak of this mining area, which is included in the first mineral resources of UNESCO because of its unique history and peculiar architectural style.
Sardinia, located in the western part of the Italian peninsula, on the French island of Corsica, is the second largest island in the Mediterranean, with an area of 24,000 square kilometers and a population of about 1.62 million people. At the beginning of the eighteenth century, Sardinia was already famous in Europe and the United States, and in 1805, Napoleon led the French to occupy Italy, and appointed his son Beauharne as his deputy to manage Italy, and he once told him that Sardinia would become a "land of nobility" without destroying its history and culture.
To this day, the Italians still give Sardinia the privilege of almost autonomy, and the people of the island enjoy the same privileges as the Italians, and no monuments can be destroyed, which has amazed many tourists and literati, and called Sardinia "the island of art" and "the capital of sailing".
In fact, Sardinia not only has a pleasant climate, but it is also the birthplace of copper and silver mining in Europe, according to the "Aegean Industry", Sardinia had primitive metallurgical processes as early as 2800 BC, which were introduced to the interior of Europe through Roman merchant ships.
After the First World War, the rapid development of industry in European countries, the demand for minerals also increased, Sardinia because of coal, copper, silver, lead and other rich mineral resources, became the best choice, Germany bought a lead and zinc mine in Sardinia, but due to traffic problems, the production efficiency has not been improved, until a talented engineer arrived.
The Germans, who had miscalculated both the mineral deposits and the water level in the Mediterranean, set the entrance to the mine halfway up the mountain, and then transported the mine by train to a port more than 700 kilometers away and then to Germany. However, with the increase in mining, the height of the tunnel was also reduced from one hundred and fifty meters to more than twenty meters, which made mining more difficult, and the hastily built port to save trouble was not a safe place, and even in good times, it would take more than a week to fill a new ship, which made manpower more difficult, and finally had to be given to Belgium at a lower rate.
After Belgium took over, it became a "hot potato", not only low profits, but also time-consuming and labor-intensive, and very dangerous, so they hired the Italian Vecelli, let him carry out a transformation, Vercelli is a famous Italian "architect", he followed his father to the Mediterranean Sea to fish since he was a child, so he knows the terrain here very well.
It took more than a year for Vecelli to come up with the bold idea of carving a new passage into the rock face, then parking the cargo ship near the hole and transporting the ore to the dock with a robotic arm, which not only saved a lot of manpower and material resources, but also greatly improved the safety of the ship. This ingenious design, even a hundred years later, was praised by mining experts in Europe and the United States as a "strange and ingenious design".
In 1924, Sardinia saw the emergence of Europe's first automated mining transport system, initially driven by human power (later improved steam engines), which could transport minerals from the mine to ships, saving 70% of production costs. At that time, the daughter of Vercelli had just been born, so people changed her name to "Port of Flavia".
At that time, most of the mining companies in Europe were still in a state of manual handling, only a few companies had "high-end" semi-automatic transportation technology, and there were not many automated vehicles such as Sardinia and the port of Flavia, and for a time, the world's most exotic mining field attracted the attention of many competitors.
The Port of Flavia is undoubtedly a groundbreaking initiative in promoting industrial development, which is why it was included in the first list of global mineral resources by UNESCO. At its peak, about 550 tons of iron ore could be mined in a day, and the Germans had to turn to Belgium for cheap minerals, and the latter had earned it back in less than two years. So, before the Second World War, Germany expelled Belgium and occupied the port of Flavia again, while Italy acquiesced to this.
Because this mine was used to make instruments, and it was also the lead necessary for making cannonballs, so when the German-Italian island of Sardinia was bombed by the coalition forces, the Germans immediately camouflaged the port of Flavia, allowing the coalition troops to discover this place, but they did not discover this place until Italy surrendered and the Germans retreated, according to the guide's description, when de Gaulle received news from the port of Flavia, he ordered to check whether mining could be carried out, but the next day, the coalition forces mistakenly triggered the conveyor belt, which took dozens of tons of minerals all"Poured" into the Mediterranean.
It wasn't until the 90s, when the port of Flavia was closed due to the depletion of its resources and became a World Heritage Site, that two mining areas were opened to visitors, allowing them to experience first-hand what was once known as the "mystery of mining technology" and at the same time to experience the entire mining process.
In 2018, a diving team discovered a piece of silver at the bottom of the Flavia cave, and Italian geographers rushed there, where they found a large amount of gold, which may have been estimated to be more than 10,000 tons. Strangely, there were signs of mining in those areas, but all the entrances were sealed off until early 2020, when a German geographer stumbled upon a World War II mining record, and the Germans had long noticed that there were a lot of untapped deposits underground, and out of hostility, they decided to keep the secret and seal off the tunnel.
Sardinia's decision to temporarily suspend its visit to the port of Flavia, after careful surveys, also confirms some rumors about the Germans, who left some "secrets**" in caves during their retreat, and others say that they found some Roman statues and ancient books. As for whether it is true or not, it will only be known after the official announcement of Sardinia.
