12. What are the main factors affecting blasting work and blasting quality in open pit mines
the quality is not only related to the properties of ore and rock, geological structure, the performance of explosive, but also related to the blasting method, initiation method, hole layout and parameters
13. Common blasting methods, initiation methods and their respective characteristics in open pit mines
chamber blasting method: a large amount of blasting, concentrated explosives, a large amount of ore and rock, no need for large-scale perforation equipment. But after blasting, the size of ore and rock is uneven, the content of unqualified rock is large, the amount of secondary blasting is high, and the working conditions are poor
shallow hole blasting method: the construction machinery is simple, easy to operate and flexible to use, which can ensure the blasting quality
exposed blasting method: the explosive is directly placed on the surface of the blasted object, and the unit explosive consumption is 3-7 times higher than other blasting methods. But it's easy to operate, and it doesn't need drilling and other preparatory work, so the construction is fast and labor-saving. Generally, the safe distance should be more than 400m
deep hole blasting method: deep hole blasting can provide enough blasting ore and rock for large mining and loading machinery; High mechanization of perforation, fast construction and low labor intensity; It can obtain better crushing effect and ideal explosion size; The unit drug consumption is low; The safety is high. But the preparation work is complex, energy consumption is large, and the piercing equipment is bulky, which requires a flat working plate
spark initiation: simple operation, no need of instrument inspection. But the quality of fuse is not easy to check, and the safety is poor
detonating with detonating cord: high safety, simple network connection, easy to master, and easy to handle misfire, but it is impossible to check the detonating cord when filling the blast hole, so the construction should be careful

4. Double mining generally refers to "picking medicine" + "mining". Every main city has a professional trainer. You can go to Dalaran city to study directly at 80, ask the guards, and the map will mark you with a small red flag, which is the corresponding trainer
mining is usually done on the map of glacier crown for daily tasks and mining. The mineral is the satiron mine
herbs are collected in the socala basin. There are many kinds of herbs in mantufei bar, covering all kinds of herbs in WLK
National Service WLK, mining and medicine collecting, do not follow any route, they are randomly refreshed, and there are too many refresh points. If you follow the so-called route, someone else may just finish mining in front of you. There is no need to specially pick anything valuable for mining and medicine picking of Grade 80. Basically, you can pick what you see on a certain map. There are few centralized categories for you to pick
the most valuable grasses are ningshenhua, yinyecao and digencao, which are also called Earth grasses, because few people provide them
the most valuable mines are copper mine and bronze mine for the same reason
however, the earth can't fly because of the single specific efficiency, the double mining has no efficiency at all, and the refresh time has not been adjusted, which is very slow
the level 80 map can fly. It's cool to ride 310% of the speed big birds to grab mines and grass, and the efficiency is much higher
at Grade 80, there are special minerals and grasses, Titan iron ore and snow lotus, which can be met but not sought. It is impossible to specially mine them
to sell goods, you usually find those who have received goods for a long time on the trading channel, set the price, and sell them to the other party by paid mail. The price is a little lower than that of the auction house. Because the auction house has to collect taxes, the price is relatively high
that's basically it. Remember to adopt me~

6. Contract trading refers to the trading of a specified quantity of goods at a specific price by both parties through a trading contract in the exchange and at a specific time and place in the future. Contract trading is developed on the basis of spot forward contract trading, which is a new trading mode of trading standardized contract in the exchange
the difference between contract transaction and spot transaction is that spot transaction is the real transaction of goods; The contract transaction is a standardized contract transaction with a certain commodity (such as cotton, soybean, oil) or financial assets (such as stocks, bonds, etc.) as the subject matter. With the emergence of digital assets such as bitcoin, digital asset derivatives with digital currency as the subject matter graally appear in the field of digital assets. The ultimate goal of contract trading is to find the real price, rather than the transfer of commodity ownership. We can avoid the uncertainty risk caused by the change of spot price through trading contracts. In addition, we can make profits through arbitrage or speculation on contracts, To ensure leverage and stable market behavior. Currency security does not charge any fees in the process of fund rate transfer, which is a direct fund transfer between the long and short sides
what is marked price
as the main reason for compulsory position closing (forced closing) is the unrealized profit and loss of position, and the maximum leverage ratio of perpetual contract can reach 20 times, it is very important to accurately calculate the profit and loss of position in order to avoid unnecessary forced closing
the intrinsic value of a contract is the core foundation of a perpetual contract. The price index is obtained by referring to the weighted average of the prices in the major trading markets, and the price index is the main component of the marked price
the price index refers to the price of a basket of major spot trading markets and the weighted average of the trading volume. The reference trading markets include: bitfinex, binance, Huobi, okex, bittrex, hitbtc
assuming that we temporarily set the price index as the spot price, we use it to calculate the marked price (used to calculate the floating profit and loss of each trading pair). The actual profit and loss of the account shall be subject to the market price at the time of closing
