Mining in Daqing Oilfield

1. Because bitcoin is based on workload proof, it is related to computing power. To have computing power, we need to consume power, so its power consumption is very large. It is precisely because of such a large power consumption that the safe and stable operation of bitcoin system can be guaranteed. "“ According to the data of btc.com website, up to now, the computing power of the whole bitcoin network is about 51.65eh/s, which is equivalent to 1.84 million bitcoin S15 (28T computing power, 1596w power) mining machines in operation, and the daily power consumption is about 69.92 million kwh. Divided by the current proction of 1800 bitcoins per day, excluding other costs, each bitcoin consumes 38800 kwh of electricity
previously, graphics cards were sold out because of the strong purchase of gold miners. The algorithm design of bitcoin is more and more difficult to dig. Therefore, the investment to dig the same bitcoin now is many times higher than a few years ago. Since the "mining" incident in Daqing Oilfield was exposed, the local police have counted the number. The average electricity cost of the mining machine seized is close to 500000 yuan in one month, and if it steals electricity, it is equivalent to making 500000 yuan in vain.

2. In the undergraate specialty catalog, only "mining engineering" is related to mining, and petroleum engineering, mineral processing engineering and mineral resources engineering are also related to mining

1. Income from mining right price

Article 10 of the measures for the administration of mineral resources mining registration stipulates that "if an applicant applies for the mining right of the state funded exploration and has verified the mining origin, the applicant of the mining right shall, in addition to paying the fee for the use of the mining right in accordance with Article 9 of these measures, also pay the price of the mining right formed by the state funded exploration which has been assessed and confirmed..." The annual income of mining right price in Heilongjiang Province in recent seven years is between 172-210 million yuan, as shown in table 4-6

2. Income of mineral resources compensation fees. The compensation for mineral resources shall be calculated and levied according to a certain proportion of the sales revenue of mineral procts

From 2002 to 2008, the income of mineral resources compensation in Heilongjiang province increased year by year, from 556 million yuan in 2002 to 1 355 million yuan in 2008, an increase of 175 million yuan year on year compared with 2007. One of the important experiences to achieve this success is to establish the focus of tax collection and management and to achieve a breakthrough in strengthening service. Daqing Oilfield is a super large mining enterprise in China, and it is also the main source of mineral resources compensation fee in Heilongjiang Province. The income of mineral resources compensation fee accounts for more than 90% of the total income. The data in 2002 shows that it is 93.16%, as shown in table 4-7, 4-8 and 4-9. In the past, the mineral resources compensation fee was collected in a fixed way, which resulted in a certain gap between the amount to be collected and the amount actually collected. In the past, the quota levy was changed to specific levy, which basically realized the collection of accounts receivable. According to this mode, Heilongjiang provincial tax collection and management organs focus on coal and other mines, comprehensively promote and promote the implementation of the receivable target in the whole province, improve the collection amount, and make the mineral resources compensation fees to achieve the receivable

Table 4-8 the proportion of compensation income of main mineral resources in the total annual income in 2002 Units and indivials within the territory of the people's Republic of China that mine mineral procts or proce salt (hereinafter referred to as mining or procing taxable procts) as prescribed in these Regulations are taxpayers of resource tax (hereinafter referred to as taxpayers) and shall pay resource tax in accordance with these regulations. The taxable amount of resource tax shall be calculated according to the taxable quantity of taxable procts and the prescribed unit tax amount. Since 2004, the state has successively raised the coal resource tax standards of 23 provinces (autonomous regions and municipalities), and raised the resource tax standards of crude oil and natural gas nationwide. Among them, the crude oil resource tax of Daqing Oilfield has reached the highest standard stipulated in the regulations, that is, 30 yuan / ton, and the natural gas resource tax has reached 14 yuan / thousand cubic meters, only 1 yuan lower than the highest standard. The income of resource tax from 2002 to 2006 is shown in table 4-10
