1. Server must have brush machine plug-in! There's a chance that the brush will brush out the ore!
2.
1. First of all, use stones or other blocks to place them as shown in the figure
3. Some of them have PVP mines, some of them are novice mines, and some of them can do tasks without PVP mines
4.
1. Stone PICK: as iron ore needs at least stone pick to dig (DIAMOND ORE needs iron pick), so more stone pick should be prepared when going down the mine. If there are only wooden pickaxes at the beginning, it is recommended to carry a workbench with you, so that you can synthesize stone pickaxes after digging round stones
Torch: torch is composed of coal mine and stick. In the beginning, no coal mining partner could get coal by burning logs in a furnace3. Food: players in peace mode don't take it. Players in difficult mode, if they don't want to be scared by zombies, Xiao and coolie who jump out every minute, bring some food. It's enough to bring some wheat in the early stage
4. Water: in case of magma excavation, it can be immediately watered out to ensure survival
Other: furnace, worktable, furnace can melt iron ingot and other ores, iron ingot can make pickaxe; The worktable can make us better survive in the underground, and even place a small home in the mineHow can a novice mine without getting lost:
1. First, dig a 2x2 square, with Steve (you) facing the torch
The next torches are all inserted on the left side (or on the right side), and then the main mine is excavated to dig out the three square blocks in front (that is, the three square blocks circled by yellow triangle in the figure)5. The butt joint of two steel plates with the same thickness is made of Q235-A steel. The known weld length is 100 mm and the plate thickness is 8 mm[ σˊ t] How much tensile force can the weld bear
by formula σ＝ F/L δ 1≤[ σˊ t] F = L δ 1[ σˊ t]
it is known that l = 100 mm = 10 cm δ 1 =8mm=0.8cm σˊ T = 167mpa = 1670kgf / cm2
then: F = 10 × zero point eight × 1670 = 13360kgf
A: the maximum tensile force of the weld is 13360kg.

A: the maximum tensile force of the weld is 13360kg.
6. STC microcontroller is to first click the button to download the program, and then power on the microcontroller system, in order to download the program
take a closer look at step 5.
take a closer look at step 5.
7. To make a house, it should be closed, the space should be larger, it should be black, and it can't put light things.
