Types of mining
1. The number of cryptocurrencies of mining type is limited. For example, the total amount of bitcoin is only 21 million (only about 4 million), and the total amount of Leyte is only 84 million (only about 20 million)
2. The difficulty of mining cryptocurrency is increased and the reward is halved. Mining is becoming more and more difficult, and the reward for digging money is also halved. For example, bitcoin design is to halve the mining reward every four years, and lightcoin mining reward will be halved soon
3. Mining costs are getting higher and higher. Mining needs to buy Mining machinery and electricity, low-cost electricity is difficult to find
for information about cryptocurrency, you can pay more attention to coin e-commerce to learn about it
if you are enchanted, you can enchant your gloves. Mining skill + 5
if both are, I don't know if it is + 10
there is a rule in the place of mining
multiply the current monster level by 5. That's your mining points
for example, if the monster in thorn Valley is level 38, then 38 * 5 = 190. That is to say, you can dig almost this point. Or earlier
if you go to Outland at level 60, 60 * 5 = 300, you can go to Outland after you reach 300 mining skill points
this is probably the rule. If you open the big map and click on each map, you should see the monster level of the map. Do it yourself.
1. Different properties: open pit mining, also known as open pit mining, is the process of removing the covering on the ore body to obtain the required minerals and extracting useful minerals from the open surface stope. Underground mining refers to the process of extracting ore from the ore block of underground deposit
The open-pit mining operation mainly includes perforation, blasting, mining and loading, transportation and mping. According to the continuity of operation, it can be divided into discontinuous, continuous and semi continuous. Underground mining is realized by four steps: deposit development, ore block preparation, cutting and stoping The main technologies of open-pit mining are as follows: see open-pit mining boundary; Slope stability of open pit mine; Mining technology; Mining proceres; Open pit mine development; Dry drainage; Mine environmental protection, mine land reuse; Open pit proction scheling. There are many kinds of underground mining methods. Based on the ground pressure management method, the commonly used underground mining methods are divided into three categories: natural support mining method, artificial support mining method and caving mining method
extended data :
characteristics
mines that convert open pit mining to underground mining are usually steeply inclined deposits with deep ore body extension, low overburden and medium thick or large thickness, In the early stage, open-pit mining was generally used, but when the open-pit mining continued to deepen, these mines graally transited from open-pit mining to underground mining, and finally turned to underground mining
Therefore, when designing the transition from open-pit to underground mining, it is necessary to make a unified and comprehensive plan for the mining in the previous and future stages The development system in the later stage of open-pit mining should not only consider the utilization of underground roadways, but also make full use of the relevant engineering and facilities of open-pit mining to make the smooth transition from open-pit mining to underground mining and keep the mine output and economic benefits stablelike other fine gold mines, the chance of procing sapphire in rich fine gold mines is about 5%
if the grade is stone / coal mine stone, any pick can be used
if the grade is lapis lazuli / iron ore, other than wood pick and gold pick can be used
if the level is diamond / RUBY / emerald, iron pick and diamond pick can be used
if the level is obsidian, you can use diamond manuscript
the level display can help you dig out the pickaxes needed for the block, so as to avoid wasting the pickaxes in vain.
