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.
Mining means that users download software from personal computers and then run specific algorithms to get corresponding bitcoin after communicating with remote servers
bitcoin is a kind of network virtual currency. Internet users can use bitcoin to buy some virtual goods, such as clothes, hats and equipment in online games. Internet users can also use bitcoin to buy real goods
bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware, and the miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by the miners, so the competition for mining is very fierce
bitcoin mining started with low-cost hardware such as CPU or GPU, but with the popularity of bitcoin, the mining process has changed greatly. Nowadays, the mining activities are transferred to the field programmable gate array, and the hash speed can be achieved through optimization. The mining efficiency of this mode is very high
{rrrrrrr}
extended materials:
the founder of bitcoin:
on November 1, 2008, a person who called himself Satoshi Nakamoto posted a research statement on a secret cryptography review group, stating his new idea of e-money - bitcoin came out and the first transaction of bitcoin was completed
bitcoin has got rid of the constraints of third-party organizations with the help of Internet, which Nakamoto calls "regional chain". Users are willing to dedicate the computing power of CPU and run a special software to be a "digger", which will form a network to maintain the "regional chain". In the process, they also generate new money
trading is also extended on this network. The computer running this software can solve the problem of irreversible code, which contains several trading data
the first "miner" to deal with the problem will be rewarded with 50 bitcoin, and the relevant trading area will join the chain. As the number of "miners" increases, the difficulty of each puzzle also increases, which keeps the proctivity of bitcoin in each trading area at about 10 minutes
in 2009, Nakamoto designed a digital currency, namely bitcoin. The booming bitcoin market has gone up and down, and the identity of its founder "Nakamoto" has always been a mystery. Rumors about "the father of bitcoin" involve from the US National Security Agency to financial experts, and also give bitcoin a mysterious aura
Bitcoin mining is a process of using computer hardware to calculate transaction confirmation and improve security. Bitcoin is a reward for miners to calculate and confirm
bitcoin also has a hype mode. Similar to bitcoin, there are also flow ores. Flow ores also have ways of trading and speculation, but the mining principle of flow ores is different from bitcoin. Flow ores mainly collect the idle bandwidth of miners and give them rewards
in fact, the blockchain technology adopted by bitcoin is more valuable than itself. This is a new way of information storage. The data is stored in all devices connected to the network. When new devices join, the information will be updated automatically, and all devices have the right to read the information
to understand the significance of bitcoin from the perspective of currency, we need to understand the currency itself first, and then compare it with the characteristics of bitcoin. After comparison, I think that bitcoin is a very high-quality currency, but some people don't think it is. They mainly question the formation mechanism of bitcoin and the lack of national credit as guarantee. They think its foundation is relatively weak
at present, there are quite a lot of arguments about bitcoin in academic circles. For example, if the total amount of bitcoin is certain, then whether it will cause deflation or inflation has different views. I think it's deflation, and the value of bitcoin will be higher and higher
at present, bitcoin still means a little bit of a safe haven currency. When the news of brexit came out, the transaction price of bitcoin rose by 20% - 30% to about 4500 yuan / piece
the biggest difference between bitcoin and other virtual currencies is that the total amount of bitcoin is very limited and it has a strong scarcity. 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 21 million
the concept of bitcoin was first proposed by Nakamoto in 2009. Bitcoin, also known as bitcoin, is an open source software designed and released according to the idea of Nakamoto Tsung, and a P2P network built on it. Unlike most currencies, bitcoin does not rely on a specific central issuing institution. It uses distributed databases throughout the P2P network nodes to record currency transactions, and uses cryptography design to ensure the security of all aspects of currency circulation
because there are too many mines, you can't remember them at all
the key is to let you do it yourself
generally there are mines in the surrounding area of the map, and there are no mines in the middle of the map
as long as you see where there are mines, you will remember that point, that is the refresh point, If you don't go there next time, it can only be said that you have been poached by others and haven't been refreshed yet.
of course,
if you don't run around several mines, it's suggested that you don't run according to the rules and run without rules, so that you won't be afraid that someone in front of you has poached the mine. If you want to be a miner, you can only take your time. In fact, you only need to dig a few times to know the point
