Mining frame

1. The difference between mining by Sifang computing power users and mining by mining machines purchased by indivials is as follows:
①. Early stage investment: Sifang computing power provides, which saves users this link. Indivial: purchase of mining machine, selection of mining machine model, preparation of power facilities, etc
2. Field equipment: provided by Sifang computing power, users can save this link. Indivial: rental site, mining machine support rack, noise elimination equipment, etc
3. Software assembly: provided by Sifang computing power, users do not need to master professional knowledge. Indivial: learn professional software assembly knowledge or hire a special person to operate
4. Maintenance: Sifang computing professional technical team, all-weather supervision and maintenance. Indivial: employ professionals to supervise and maintain all day long< (5) electricity and electricity charges: professional large chain mines and users do not need to pay electricity charges. Indivial: the power facilities in the residential area are unstable, the price is high, and the cost-benefit of mining is unbalanced< (6) risk taking: users obtain BTC net assets. Indivial: the equipment investment in the early stage is huge, which is easy to form heavy asset operation, and the income and investment in the later stage are likely to be unequal.

Mining needs high-end graphics card, mining equipment is the first to eliminate NV graphics card. Mining must be done with graphics cards. The overall structure of mining equipment and ordinary PC machine is different is the number of graphics cards. You can install four or eight through pic extension

after expansion, an expansion shelf needs to be made. To fix the graphics card and other equipment, we need to get some fans on the shelf to cool the graphics card

CPU is not very important. But not lower than i5< br />

4. Graphics card uses GPU for general purpose calculation. So it can stack hundreds of stream processors awesome. Each stream processor is like a small CPU. Although its ability to run complex programs is far from the power of CPU, it can not support many processors, so the actual performance, especially the single precision floating point performance, is much stronger than that of CPU. The actions in bitcoin can be regarded as the use of graphics card to do continuous general computing, and the computational complexity is relatively low and quite repetitive. The stream processor used by graphics card is just suitable for such an algorithm.

5. According to the proction function, underground mining equipment is divided into several parts, mainly including: 1. Fully mechanized mining face equipment (Shearer, scraper conveyor, transfer machine, crusher, belt tail, belt conveyor, pump station, power center, hydraulic support, transport vehicle, support handling tractor), 2. Main transport equipment (belt conveyor, screening crusher), 3. Main lifting equipment, Main ventilation equipment (fan), 4. Central substation equipment (mine flameproof transformer, power distribution device, integrated protection device), 5. Central water pump room equipment (water pump), 6. Tunneling equipment (roadheader)
all equipment are of specified models. The selection of equipment should not only take into account the economic and technical indicators, but also should not be conformed to the rules. In the process of use, unknown mining environment may appear, so the flexibility of equipment must not be ignored. These large equipment often cost millions of money!

6. Of course, it's accurate. The data comes from the chain. The blockchain can't be fake. Now there's a lot of data on gikee. It's said that there are more than 3000 projects, which are quite complete.

7. The so-called "mine" is virtual currency. There are many kinds of virtual currencies, among which bitcoin is the most famous. The concept of bitcoin was first proposed by Nakamoto in 2009. According to Nakamoto's idea, open source software was designed and released, and P2P network was built on it. Point to point transmission means a decentralized payment system. Unlike most currencies, bitcoin does not rely on a specific monetary institution to issue, it is based on a specific algorithm, through a large number of calculations. Bitcoin economy uses the distributed database composed of many nodes in the whole P2P network to confirm and record all transactions, and uses the design of cryptography to ensure the security of all aspects of money circulation

8. According to the classification, the ore block is divided into room and pillar. Mining room before mining pillar (Mining in two steps). The goaf formed by stoping room can be maintained by using the strength of pillar and rock itself. Therefore, the ore and surrounding rock are stable, which is the ideal condition for using this kind of mining method
the second type: filling mining method
two-step mining. When stoping the room, with the advance of the working face, graally fill the goaf with filling material to prevent the surrounding rock from falling, and manage the ground pressure by filling the goaf. Under indivial conditions, support and filling materials are used to maintain goaf and manage ground pressure
the third type: caving mining method
one-step mining, with the advance of the mining face, the surrounding rock collapses to fill the goaf at the same time, so as to achieve the purpose of management and control of ground pressure. Therefore, it is a necessary prerequisite for the application of this kind of mining method that the caving surrounding rock fills the goaf

open stope mining methods are divided into
comprehensive mining method
Room and pillar mining method
shrinkage mining method
sublevel room mining method
stage room mining method
filling mining method
single layer filling mining method
upward horizontal slicing and filling mining method
upward inclined slicing and filling mining method
downward slicing and filling mining method
separate mining and filling mining method
box support filling mining method
caving mining method is divided into:
single layer caving method
slicing caving method
sublevel caving method with sill pillar
sublevel caving method without sill pillar
stage caving method
hope you are satisfied and adopt...
