Shanxi mining treatment

1. Large state-owned mines range from 3000 to 6000, with complete insurance, and indivial black holes will cost you life, let alone money
Datong has the most coal mines.

2. In Shanxi,
is not a big mine. There are more than 30 million tons of coal mines in Pingshuo and Luliang< The profit mainly depends on the cost. Generally speaking, the comprehensive cost of coal mining in private coal mines is relatively low. The profit is relatively high. The cost per ton of coal is about 200 yuan. If the coal type or quality is good, the raw coal can also be sold at a high price. The quality of clean coal after washing is better. The price is also higher
simply calculate, if raw coal can buy 400 yuan per ton, the profit will be 200 yuan per ton. 500000 tons, just one billion
if you wash jiadandan zheganfei and surpass Jianggong, the price of clean coal will be higher and the profit will be higher
private
more than 5 million tons is very powerful

3. In fact, it's a bit impossible. There are many people who make more money, but there are only one or two in China's billion, not to mention the large number of people like Shanxi. In Taiyuan, there are many rich people, but there are many poor people - and there are many poor people. You know, the GDP of Taiyuan, the capital of Shanxi Province, is not as good as Nanchang, which is very poor, because there are too many poor people!

4. Learn mining. I'm a senior, and I want to go to Shanxi now

5. Mining needs a lot of qualification proceres. It's very troublesome. People can't afford to be prosecuted.
if you want to dig, it's better to find a mine to pick up. However, if you find all the technical ones, you can pick them up~

6. Theoretically speaking, 100 households is no problem. The actual operation depends on your requirements for network speed. There is also the problem of computer room. Sometimes one person may use the card. You say that you want to share it with several households. It's not good to help you refer to the downlink

7. It's better to go to Shanmei than to go to coking coal,,

8. 100m optical fiber can be used by several computers. The answer is different according to different application scenarios. Let's talk about it in different situations<

100m symmetrical optical fiber for uplink and downlink
100m symmetrical optical fiber for uplink and downlink, which mainly appears on the special lines of medium and large enterprises. According to the application scenario, it's just a simple web application. 300 computers are OK. This one used to use Telecom to do village in city broadband. If there is watching video in the middle, it depends on the definition of the video. On the computer, 8-10 megabytes of bandwidth can be used to watch HD format smoothly. On the mobile phone, I don't have a 6 megabyte card to watch HD. I will watch the number of people watching video at the same time according to the number of computers I bring. If there are external server applications, data transmission more, will also occupy a lot of bandwidth. Generally speaking, it's no problem to bring more than 50 units under proper management<

100MB uplink and downlink asymmetric optical fiber
this kind of dial-up optical fiber is usually used for home broadband or small and micro businesses. The downlink is 100MB, the uplink is the smallest 2MB, the largest 20MB, and it may be about 8MB in general. Without consuming a lot of uplink bandwidth, this is not different from the above symmetrical optical fiber. But in the application of transmitting files, sending large attachment e-mail, P2P download, online video and so on, which will proce a large amount of uplink bandwidth, it will seriously affect the network, a serious machine download will use up the uplink, and the whole network is basically paralyzed. For each IP reasonable limit uplink and downlink bandwidth, good management, 8 megabytes uplink, with 30 computers is OK.

9. 100m optical fiber can ensure that 100 devices can access the Internet at the same time
1. 100 MB optical fiber refers to the optical fiber network traffic can reach up to 100 Mbit / S (stand-alone test). Bit is byte, one byte is 8-bit binary code (composed of 0 and 1), 1m = 1024 bytes, that is: 100M = 100x1024x8 = 819200bit

2. Optical broadband is to convert the data to be transmitted from electrical signal to optical signal for communication. The two ends of the optical fiber are respectively equipped with "light cat" for signal conversion
3. Optical fiber is one of the most ideal transmission media in broadband network, which is characterized by large transmission capacity, good transmission quality, small loss, long relay distance and so on. Optical fiber transmission uses wavelength division multiplexing, that is to say, the data of multiple users in the cell can be used as a high-speed signal by PON technology, and then molated to different wavelengths.
4. The difference between optical fiber broadband and ADSL access mode is that ADSL is the transmission of electrical signal, and optical fiber broadband is the transmission of optical signal.

10. The current important strategic direction of jinwowo is to study the blockchain technology and implement it to the commercial application level to help more small and medium-sized enterprises make good use of the advantages of big data and create a truly interconnected and shared "value Internet"
jinwowo will use blockchain technology to fully record big data sources and improve storage. Because of the distributed accounting mode of blockchain technology and its full history, it can break through the monopoly of instry giants on big data, and greatly improve the quality of data and the scope of collection.
