Mining Foundation

1. Because indivial mining is difficult to meet the demand, the global computing power is increasing, and it is difficult for a single device or a small amount of computing power to dig bitcoin again. It is also a combination of a large number of mining machines to form a mine pool. The computing power of the mine pool is very powerful, and it can also ensure that virtual currency can be g more quickly. So how can the mine pool dig? Let's have a look
how to mine a mine pool
the location of a mine pool is also very particular. It's not that a mine pool can be built anywhere, but it needs early-stage capital investment. A mine pool is to combine a single mining machine together. Because of the collection of many miners' computing power, the computing power of the mine pool accounts for a large proportion, and the probability of digging bitcoin is higher. The mine pool will distribute rewards according to the contribution value of each equipment
there are many mines all over the world, and the scale of each mine varies from big to small. Generally, small mines no longer have great advantages. Large mines have many miners for mining. For each miner, he can join any mine or join multiple mines at the same time, The first task of the mine pool is to distribute the income to the miners
(1) PPLNs method
this method gathers the shares g by all miners together. Whenever a certain amount of shares is accumulated (generally 30 million shares), the mine pool will allocate the profits of the previous stage to the miners according to the proportion of contribution
in this way, the income of miners depends entirely on the time needed to dig 30 million shares in the mine pool. If you are lucky, you can dig them in a short time, then the income of miners will be more, otherwise it will be less. In return, the pool charges a 3% tax
(2) PPS mode
for users, the income of this mode is relatively stable
the profit mainly depends on the miner's mining speed. As long as the mining speed is stable, the corresponding profit can be obtained, and the profit is real-time, that is, the mine pool will pay the profit for the miner while the miner is running
obviously, every time a block is calculated, the mine pool has paid for all the miners. If the block fails in the subsequent confirmation link, all the losses will be paid by the pool operator. Therefore, this method reces the risk of the miners, but transfers the risk to the pool operator
therefore, usually the ore pool can charge a handling fee to make up for the possible losses caused by these risks. In this mode, the tax of the ore pool is 7.5%
the above is about how to mine. The difficulty of mining has greatly increased, but the mining army is expanding. If the basic equipment does not meet the standard, it will be difficult to gain in the mining instry, because the value of the virtual currency may not be equal to the price of an equipment, and many miners are not just digging bitcoin, Instead, we choose other virtual currencies to mine.

5. There is no division between geological survey and mining. General geology, surveying and petrology are the basis. The rest should be divided into mineral resources and mining methods

6. Hello, first of all to your province's personnel network to see, there are clear methods. Generally, you should first check whether you are qualified for registration, and then register online. After successful online registration, you will arrange on-site audit for a period of time

7. I am a mining and geotechnical engineering major in Central South University, and my major course is mining economy; Open pit mining; Controlled blasting and demolition blasting; Development trend of mining engineering discipline; Use of large software for mining and underground engineering; Introction to pressure supply and discharge; Introction to mining; Mine ventilation and safety; Underground mining of metal deposits; Soil mechanics and foundation; Filling theory and technology; Slope engineering; Roadway and tunnel engineering
the postgraate entrance examination requires professional courses, mathematics and politics. The engineer is generally allowed to take the examination three years after graation. Otherwise, it depends on your working time and experience in the mine. You will be qualified as an engineer without taking the examination, but intermediate and senior engineers need to take the national examination

8. Brother, you are in the water bar...
it's no use drinking water here, thank you. In addition, you will report if you are drinking water again...
if you are really asking a question, please describe your question clearly. Thank you
please adopt or delete the problem. Thank you. If you understand the wrong question, you can ask me from the wheat block or ask me

9. The design manual of coal mine is more professional; Coal mining, coal mining and other books as understanding should be enough. In addition, I think if you really work in coal mines, I suggest you learn more about mining, and the development space is much larger than geology.
