Can an individual mine in ancient times
You can't dig in a day. It takes 2000 years
the global unified computing difficulty of bitcoin is 2621404453 (expected to change in two days). It takes more than 2000 years for a 2.5GHz CPU to work out a bitcoin
in order to make the graphics card fully loaded for a long time, the power consumption will be quite high, and the electricity bill will be higher and higher. Many professional mines at home and abroad are operated in areas with extremely low electricity charges, such as hydropower stations, while more users can only mine at home or in ordinary mines, so the electricity charges are not cheap. Even in a certain residential area in Yunnan, there was a case of crazy mining, which led to a large area trip of the residential area, and the transformer was burned

bitcoin network generates new bitcoin through "mining". In essence, the so-called "mining" is to use computers to solve a complex mathematical problem to ensure the consistency of bitcoin network distributed accounting system
bitcoin network will automatically adjust the difficulty of mathematical problems, so that the whole network can get a qualified answer about every 10 minutes. Then bitcoin network will generate a certain amount of bitcoin as block reward to reward the person who gets the answer
when bitcoin was born in 2009, block rewards were 50 bitcoins. Ten minutes after its birth, the first 50 bitcoins were generated, and the total amount of money at this time is 50. Then bitcoin grew at a rate of about 50 every 10 minutes. When the total amount reaches 10.5 million (50% of 21 million), the block reward will be halved to 25
when the total amount reaches 15.75 million (5.25 million new output, i.e. 50% of 1050), the block reward will be further halved to 12.5. The monetary system used to have no more than 10.5 million in four years, after which the total number will be permanently limited to about 21 million
the recognition of ore veins by the ancients was basically based on experience, and the recognition of surface mineralization marks or ore vein outcrop shape was the accumulation of long-term labor experience
for example, "pangjinshi" is regarded as the prospecting sign of gold ore in gold ore dressing, and "black road" on rocks is regarded as the sign of silver ore prospecting
for pangjinshi, there are many records in ancient books
the compendium of Materia Medica cites the collection of materia medica: "the collection of vessels says:" common people take gold, dig more than Zhang deep, to fenzi stone, the stone is a black coke, there is gold under the stone... "Fenzi stone is the companion stone<
Qu Dajun quoted Shi Xing Ji in his Guangdong new language: "when I g more than Zhang, I saw Leifu Fanzi stone, which is brown and black scorched at one end. It is a stone with gold, and there must be horseshoe gold. There is a crystal bed beside the gedansha, and a Fanzi stone beside the gold. "
in Ben Cao Yan Yi written by song Kou Zong Xun: "a lump of gold, that is, a cave mountain or a hundred feet, can be seen with gold and stone. The stone is brown, and one end is as black as fire. This can be seen with gold, and its gold is deep red and yellow."< According to Tiangong Kaiwu, "most of the gold comes from the southwest. When you take it from the cave mountain to more than ten feet, you can see the accompanying gold and stone, and you can see the gold. The stone is brown and black like fire."“ However, in the cave of the Yi ape in the south of the five ridges, the gold first came out like black iron, and then it was g deep under the black coke stone“ The method of drawing silver. There are black roads on every stone wall< In Tiangong Kaiwu: "where is the silver seedling in the earth. There may be yellow gravel, or there may be a tangled shape in the cracks between the rocks in the soil, which means that it is not far away to go to the mine. "“ Where silver is made, the reefs are made. To the broken, such as sand, its surface sub ya, such as branch shaped, said riveting, its outer ring Stone said ore (surrounding rock). The large ore is like a fight, and the small one is like a fist. It is a useless waste. Its reef sand shape is like coal, the bottom is lined with stone but not very black, and its height is several
in addition, there are some indicative plants in the place where the gold vein is located, such as a wild Allium macrostemon growing near the gold mine in historical records
Youyang Zazu: "there are alligators on the mountain and gold under it."< According to the Geng Xin jade book, the root of the mountain looks like a green vine, purple and golden
it can be seen that the ancients have accumulated certain experience for the external performance of ore veins through years of prospecting and exploration. However, in order to truly determine the existence of ore veins, it is necessary to test mining and testing to further verify whether the experience is accurate. The Ming Dynasty Lulong's Shuyuan Zaji records: "the mine of hardware was born between mountains and rivers. In the place of origin, only the vein is hidden in the hard rock, which is as tiny as a hair. Those who have knowledge of the mineral resources can get it, chisel it and cook it. "
the so-called "gouge cooking test" is to verify experience through experimental means<
as for the mining method, for placer gold and the like, the panning method is mostly used. In "Tiangong Kaiwu · hardware", it is said that "water gold... Is extracted from the river, panning for gold."<
in addition to scouring for hair, chute method is also used. According to song Zhuyu's Pingzhou Ke Tan, "Liangchuan metallurgy, taking sand along the stream and scouring with wooden plates, has little and laborious results. Deng, laijinkeng households stop using big wood, sawing it, leaving blade marks. When you throw sand on it, you will be flooded with water. When you remove the sand, you can easily get it in the golden saw pattern. "<
the gold chute is also known as "gold Liuzi" and "gold bed". The chute method was widely used in the Qing Dynasty
all of the above are gold mining methods for placer gold. For deep buried gold, mining is necessary< In Ben Cao Yan Yi, song Kou Zong Xun said, "a lump of gold is a cave mountain or a hundred feet..."
"Tiangong Kaiwu · hardware": "most gold comes from the southwest, and the one who takes the cave mountain is more than ten feet..."
all gold and silver mines are mined by rock drilling, and the cave mountain breaks into the underground. Now some ancient mine sites have proved that the ancient mining method in China has been very mature. In the Tang and Song Dynasties, the room column method was used to support the mine with wooden columns
excerpt from the fish reading club, for reference only, I hope I can help you and answer your doubts.
lumberjack was called "woodcutter" in ancient times. It is said that Gou Jian, the king of Yue, made people go to the mountains to cut wood, but they did not return for a long time. He was called "Muke Yin", so later generations called the lumberjack Muke.
