Pictures after manual mining

Mining is the use of bitcoin mining machine, which is used to earn bitcoin

one of the ways to get bitcoin is that users download software from personal computer and then run specific algorithm to get corresponding bitcoin after communicating with remote server

bitcoin is a kind of virtual currency. Bitcoin mining system is the process of carrying out mathematical operation for bitcoin network through computer hardware. Miners who provide services can get a reward, because the network reward is calculated according to the tasks completed by miners, so the competition for mining is very fierce

mining is actually a competition of performance and equipment. The mining machine composed of many graphics cards, even if it's only hd6770, can surpass the single graphics card of most users

and this is not the most terrible. Some mining machines are made up of more such graphics card arrays. When dozens or even hundreds of graphics cards come together, the graphics card itself costs money. Considering the hardware price and other costs, there is a considerable expenditure in mining

bitcoin mining process:

1. To find the ore pool

to start mining, there must be a ore pool with convenient operation and stable output. Its function is to subdivide the data packets for each terminal, and pay the corresponding amount of bitcoin according to the proportion of the data packets calculated by the terminal through precise algorithm

2. Download bitcoin miner (software)

in fact, there are many kinds of this miner, you can go to the official website to download

3. Setting mining software is a green software. After installation, we can set the language first to facilitate further setting. Next, you need to set the server, user name, password, equipment and so on. Generally, the server chooses a better network from BTC guide series, and the user name and password are set by ourselves before

4, bitcoin mining start

when we confirm that all settings are correct, click the "start mining" button to start bitcoin mining, and then the graphics card will soon enter the full speed running state, the temperature and fan speed will increase, you can monitor the state through gpu-z or graphics card driver

6. This is the standard diagram of the comprehensive mining method for the layout of transportation drift in the vein.
the small piece you refer to in the thick line is the funnel. If you look over the mining design manual, the funnel also belongs to the bottom pillar. The irregular point pillar in the center of the ore block is generally estimated by the rock drillers because they think the ore is poor there
this drawing is a plan. For the standard drawing of mining method of gently inclined orebody, generally only plan and section drawings are made.
except for gently inclined orebody, the rest are generally in front view, top view and bottom view Side view of this sequence
------------------------------------------------------------------ --
in addition, the map you sent is accurate within the vein, OK, close your eyes, according to the design of the middle section of 40m or 50m, drive a roadway along the vein at a certain height, which is the 1-transport roadway on the map, Then dig a way up the mountain at a certain position. For example, it's on the leftmost side of your map. Then, parallel to the transportation roadway, the bottom pulling roadway is g 6-8m up the mountain. Well, two working faces are formed. Mining continues at the end of the mountain, and the bottom pulling roadway breaks through. Right, mining is ahead of mining! Then, ah, sequential mining, it's what you see in the picture

however, this picture is used in the past and used in artificial mining. Nobody uses it anymore. Why can't the proction capacity go up
OK, let's look at the picture,
1. The electric harrow nest is on one side of the transportation roadway, the harrow bucket is on the other side of the transportation roadway, and the steel rope crosses the transportation roadway, which will definitely affect other operations in the roadway
2. The comprehensive method is applicable to the ore body with dip angle less than 30. If it is arranged as shown in the figure, the height difference between the floor height of the transportation roadway and the funnel mouth is relatively small, and it can barely install a wooden funnel to load ore into the car. However, looking at the things in the figure, I think that the transportation roadway is running on a two wheeled wooden frame car, which manually takes the stpan to load ore
3. The efficiency is extremely low when the funnel spacing is 8m and the ore is loaded at multiple points
4. In general, the height of the middle section of a metal mine is more than 40m. If it is 40m, then two rooms on the map can be arranged on one middle section. I don't believe you can try it in CAD^_^< br />_________________________________________________________________
in addition, this is the picture in the old book. If it's your textbook, I despise your teachers. I'm irresponsible and teach students what I learned half a century ago<

for the sake of my hard work in typing so many words, let's have a look
in addition, if you have problems in this area, you can post to me in the mining engineering post bar. I read the post every day
good luck!!!

7. If you go to the map without people, there will be more minerals and more loving stones

8. How to say that? If your husband's job changes, if it's a company transfer, then it should be a rise in position and salary. Congratulations. If your husband doesn't want to do it and resigns, you should be open to it. If he resigns, it means he must have an idea in his heart. Whether the idea is active or passive, it means he has made up his mind. If you think it's not good for your husband to change his job, you will show it more or less, which will affect your relationship, So, no matter what, when the husband has his own idea, he should learn to accept it and comfort it. Only in this way can the family and the couple be more harmonious. After all, a job is far behind the family and the relationship between them.

9. In principle, the amount of money is agreed by the parties, but the guarantee law also limits the maximum amount, that is, it cannot exceed 20% of the amount of the subject matter of the main contract. According to the judicial interpretation, if the amount of deposit agreed by the parties exceeds 20% of the subject matter of the main contract, the people's court will not support the excess.
