Mining scale

1. 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

2. Alien mining is the pioneer of large-scale mining. With bitcoin's recovery to a high of $9000, mining technology has returned to people's vision. People who have experienced the ups and downs of the currency value in 2017 are more inclined to the concept that speculation is not as good as Tun coin, and Tun coin is not as good as mining. On the whole, the author thinks that mining can be divided into three times. In the era of 1.0, which is also the era of indivial soldiers, bitcoin can be mined mainly through the background operation of computers, but that's from 2009 to 2011. In the era of 2.0, the emergence of professional mining machines has brought the computing power competition into a period of rapid development. In 2016, the emergence of a number of high computing power mining machines triggered a struggle among various mining areas. Owning high computing power mining machines means mastering the future of bitcoin. Up to now, China's computing power has reached more than 70% of the global share. Then the next stage will be the 3.0 era of high computing power regular army. As bitcoin and other virtual currencies enter the regulatory period, the system surrounding proction will follow. Therefore, enterprises with high computing power, professional services and operation qualifications have become the new choice of miners.

3. Personal understanding: the mining design is based on the mining license. The annual proction scale and inflection point coordinates indicated in the mining license are determined by the Bureau of land and resources, and after the previous multi-party argumentation, the design institute has no right to change. The development system can only be arranged according to the annual proction scale within the designated mining area. Some transport roads need to be arranged outside the boundary, and the permission of the land and resources department should also be obtained.

4. Regardless of the complexity, the proction (mining) scale refers to the amount of stonework that can be mined

5. The proction scale on the mining license refers to the annual amount of ore mined by the mining enterprise
these ore volumes are divided into 111, 111b... 333, etc. according to the reserve level

6. 300000 tons / year, which is generally expressed in this way. This is for underground mines, and for open-pit mines, it can also be expressed in cubic meters

7. Limited

8. Generally, the mining license of metal mine is the amount of ore, and the mining license of non-metal mine is the amount of mineral

9. Generally according to the scale of mining license, if it is a design institute. Now the safety supervision is in charge of this, and the mines that can't reach the scale need to be integrated or shut down

10. An annual output of 150000 cubic meters
