My world mining speed increases

1. Use a good pick, preferably a diamond pick. Then enchant efficiency 5, if there is a command box can also do efficiency 100.

2. Every 21 layers, dig a 4x4 concave surface on the right or left side of the mine, and then make a wall every other layer, and then make a 4x4x4 workstation, which is necessary in the workstation; 1x2 door, fence door, half brick X3 (one is used as a foot pad, two are used as windows to make sure your bow and arrow can fly out, and close range weapons can hurt the enemy and block the enemy's position), torch x1, bed (not for sleeping, but for rebirth point, but only for server), box (as many as possible, you know), workbench X1 (this is your own small fortress, The main purpose is to have a safe place to make manuscripts, store weapons and articles when you are in urgent need of refuge or when you run out of manuscripts; It can also be equipped with brewing table, enchantment table (one is used to make potion, one is used to improve efficiency and attack power, etc.) anvil (repair ~ you know).

3. At the beginning, I searched for mine holes by myself, vertical excavation method, rotary excavation method and fish bone excavation method. In terms of tools, the gold pick is the fastest,

4. Hello:

the question is ambiguous... If you only emphasize speed, of course, the better the manuscript, the faster the digging speed. However, there is a little cold knowledge, that is, although the rability of the gold manuscript is very low, it is a little faster than the diamond pick in digging many squares
if you want the overall mining effect, fishbone mining is recommended, that is, extending a branch road every two grids on a main line (height self-determined), so that you can search all minerals in a block without dead angle

if it helps you, please take it!

5. Without that potion, you can only enchant the pickaxe with efficiency and the urgency of using beacon.

7. The traditional high-efficiency mining method requires the branch roadways to be close together to expose all the blocks as much as possible, so as to mine all the veins. Therefore, we first assume that the distance between the two roadways is 1, that is, only one block is separated between the two roadways
there is no doubt that the first excavated branch roadway has a very high efficiency (in fact, it is the highest possible efficiency). However, the efficiency of the second lane will be very low, because most of the veins it encounters have been mined out in the first lane. The efficiency of the back branch is similar to that of the second branch. On the whole, the design of branch roadway spacing of 1 is extremely inefficient
now let's assume that the distance between the branch roadways is 2. Many people use this scheme because it can expose all the squares in a layer. However, under this scheme, the first two branch roadways will still pass through several identical veins, so it is also very inefficient
we can think that this mining scheme is not the most efficient as long as the first two branch roadways may still pass through the same vein. It can be seen that the most efficient scheme is to make the distance between the branch roadways large enough, so that it is impossible for two adjacent branch roadways to pass through the same vein.

8. If you don't use mod, you can use fishbone method. I'll give you the method link https://minecraft-zh.gamepedia.com/%E6%95%99%E7%A8%8B/%E9%92%BB%E7%9F%B3
little by little, I hope it will help you

9. Single machine: dig stairs, expand horizontal mining range
server: vertically down, looking for canyons (the canyons are rich in minerals and exposed on the surface)

10. What your friends say is true

four hours a day can earn a little card money, but if you equip with garbage, no one will sell you.
mines are also divided into low-level and high-level, and high-level mines need high skill level, which needs to be practiced slowly

finally... Point card trading is risky. After mining for several days, I was cheated ~ ~ ha ha ~ ~ tragedy
