Integral chain mining

1. Many shopping malls will have a point mechanism, and it has become a very common marketing way for consumers to send points. The application of blockchain is derived from the integral system. Through the integral system of blockchain, we can 1. Build the credit enhancement process of integral issuance, which lays the foundation for circulation; 2. The margin cashed by the blockchain integral bank is the exchange endorsement; 3. From service-oriented to user-oriented, users can transfer and exchange independently, blockchain is responsible for matching, and points play a role in market decision
4; 5. Ecological incentive mechanism is introced. At present, the domestic blockchain integration system technology development has the strength of micro three cloud technology developers.

1 Division of mining units of ore deposits generally, ore deposits occupy a large area and have abundant reserves. In order to develop in a planned way, the ore deposits are often divided into several parts (mining units) from large to small according to the occurrence conditions of ore bodies, and are classified into corresponding mining enterprises (proction units) for mining

generally, the distribution range of ore deposits is called mining area, which is usually classified as a Mining Bureau (or company). All deposits in the same geological structure and of the same origin are called ore fields (coal mines are called coalfields). If the mine field is large in scale, it can be divided into several parts, each part is mined by a mine (pit mouth), which is called mine field (Figure 12-1). The boundary of mine field can be artificial boundary or natural boundary. During mining, the mine field must be divided into smaller parts. For inclined seam, the seam is usually divided into several long sections parallel to the strike according to a certain elevation along its inclined direction, which is called stage (or middle section), and the upper and lower interface is called horizontal, such as 0m level and - 50m level (Fig. 12-2). When the stage is small, the mining can be carried out at one time along the whole stage; If the stage area is large, it should be further divided into n mining areas, each mining area along the inclined layout of n mining faces, called section

Fig. 12-8 schematic diagram of roof failure zoning

(according to Beijing Academy of Coal Sciences, 1985)

a-irregular caving; B - rule falling; C-serious fracture; D-general cracking; E - tiny crack; F - caving zone; G-fracture zone; H-overall moving zone; I-fracture zone

1) caving zone: the area where the direct roof splits into pieces and collapses downward. It can be divided into irregular caving section and regular caving section. The rocks in this area are broken and expanded, accumulated and permeable, which can form a channel for the upper groundwater or surface water to pour downward, causing water inrush. Generally, this area is not allowed to develop into the upper strong aquifer or surface water

2) fracture zone: a large number of mining fractures with cut and separated layers appear above the caving zone. The zone can be divided into three sections: serious fracture section, general fracture section and micro fracture section. When the zone reaches the supply water source, the mine water inflow will increase sharply, even cause water inrush

3) overall movement zone of rock stratum: the zone is located above the fracture zone, which is generally characterized by the overall bending deformation or shear displacement of the stratum, or the overall bending and falling in the zone. Generally, there is no fracture and it does not form a water filling channel

3. Before I tell you the scope of application, I'll talk about the function of digital signature: digital signature uses the private key of digital certificate to encrypt the abstract of data, so as to ensure the integrity, authenticity and non repudiation of data

digital signature is the most reliable and key method to ensure the integrity, authenticity and non repudiation of data. Where it is needed, it can be applied
now the typical applications are: online banking, e-commerce, e-government, network communication, etc

4. The fire chain financial app is OK. There are a lot of news and information about the blockchain, and the updates are fast.

5. I'm not sure about other things, but I heard that IPFs, a magic calculation of fire and thunder, is pretty good.

6. Now many people are using Tencent micro vision, micro vision is a good application, many people play micro vision. You can show your beauty and figure here. Even if you don't have beauty or figure, it doesn't matter, because you have real-time make-up and slim legs. Of course, you can choose to only show your talent and see other people's works. It's very interesting,

method 4) check your time and time zone
Enter iPhone 6 "Settings"
- & gt“ General "– & gt
"date and time"
- & gt
turn off
"automatic setting". If the date and time are correct, turn on "automatic setting"< Method 5) reload iBooks
try to uninstall iBooks
, and then try to install iBooks again< Method 6) reset date and time

is solved

8. Oh, what a beautiful fountain! We are visiting Little India, surrounded by flowers and trees, mango trees, betel nut trees, bread trees and so on, as well as a variety of spice filled plants, is really full of spices and flowers of little India
Why do you call this little India? This is because it is full of the most representative buildings and features of India, and it is also the favorite place for the Indian people of Singapore. Every Sunday, they will eat and chat on the roadside, from morning to evening. The crowded cars can't drive in; In Singapore, Indian culture is very distinctive.
one of the things that impressed me most was going to have a cup of tea. When I came to that leisurely restaurant, we quickly picked a seat to sit down. I looked at my Indian uncle next to me, and I found it disgusting to eat with my hands; The uncle looked at our puzzled little face, laughed and said in nonstandard Chinese: it's delicious! I also found that Indians always stick out their tongue when they eat, put food on their tongue, and then stick it into their mouth to chew food. I think this should be the cultural tradition of India. For the first time, I saw with my own eyes the Indian hand grabbing rice mentioned in the morality book. It was really hand grabbing! Thinking about it, I saw everyone gathered together, and I also pushed over. I leaned out my head and saw that the Indian master was making tea. He had a moustache on his mouth, raised his head, and straightened his chest. He looked a little funny. He held the teapot in one hand and the big cup with tea in the other hand, and slowly poured the tea into the teapot. What's so strange about that? In the end, he didn't stop until he almost straightened his hands. He pulled it so long, but it didn't leak. He pulled the tea in his hand, just like it was connected with a cup. He was really skilled! And the Indian master is not afraid of scalding. He turns pancakes directly with his hands. I really admire him! I taste the tea, sweet with bitter, really delicious! Then why is it called La cha? I think it's probably because of the long relationship when I do it
we also went to many places, such as Indian churches, Indian temples and so on. It gave me a deep understanding of Indian culture and made me understand that we should also think from the perspective of others when we look at things, such as Indian hand grasping cakes, Indian barefoot entering temples, etc. We all feel dirty and disgusted because our cultural tradition is different from theirs, They also have a direct culture, their own way of life, so we can not make fun of others, despise others, to remember: the people of all countries in the world are equal!
