My world quarry mining method
Second, select iron pick for mining
thirdly, we should choose the stepped mine
Fourth, the vertical downward mine can also be selected.
in the game, ore is a very important resource, so how to mine rock in my world is very important, so you must have a good understanding of the strategy of mining rock skills. First of all, we need to find a cave in the open air to start exploration, so as to make our exploration path move forward as far as possible, Even if very shallow caves can provide very rich coal and iron ore, there will be gold ore and other mineral deposits in the more prosperous Prefecture. If we don't find an easy cave intersection, it's OK to mine in the shaft or canyon. Of course, we can also create an intersection leading to the underground world and dig a vertical shaft at a convenient location, And then start to dig horizontally at a suitable height
when mining, we should also do some protection effects. For example, the tunnel collapse system is one of the ways to protect our mine. The reason is very simple. In fact, the miners press a button to retract the sticky piston on the wall, and then pull out the torches on the wall, so that these torches can support the sand or gravel above and prevent it from falling, When the sticky piston retracts, the torch will no longer attach to the wall, and then disappear. In this way, the sand or gravel will fall and block the tunnel. The tunnel that can be used to block the mine network will be attacked, and it can still be blocked. In addition, it can also be used to capture the attacking creatures in the isolation area to prevent them from wandering around the mine, Sneak on us while we're digging.
Let me talk about my experience (with Wiki):

in minecraft's world, mining is a frequent visitor for players. But don't just dig. Here are some great tips
< / blockquote >for example, this picture can tell you the distribution (height) of minerals in the world. It is suggested that the building owner first dig 29 iron ores and burn them into iron ingots (to make an iron pick, an iron sword and a set of iron armor), and then go to the 16th floor to find diamonds (it is suggested to dig on the 11th floor, because it is the magmatic layer)
(from wiki)
in addition, Don't forget to bring food (more is better, but don't occupy too much backpack space, 3 spaces is enough)
don't forget to bring wood, which is very useful (you can make a torch when you dig coal), and light up all the roads you walk with a torch (to prevent brush monsters)

choose one of the many open-air caves and start exploring, Try to move your exploration path down as much as possible. Even shallow caves can provide abundant reserves of coal and iron ore, and there are other deposits such as gold ore in deeper layers. The advantage of cave exploration is that it doesn't need to dig a lot of stones, but on the other hand, there are many monsters in the cave, and the terrain is dangerous. Whether it is water or lava, it will cause certain obstacles

if you don't find an easy access cave entrance, but find a shaft or Canyon, mining there is also a good choice. You can use a bucket to artificially create a waterfall so that you can swim to the bottom (or up) of the canyon, and then you can explore the caves deep in the canyon in the way described above. Watch out for falling monsters! Climbers are a particular headache. Even if it doesn't bring you death, it may make you live worse than death, and it may destroy the minerals you want to dig. You can use skilful jumps to light up cliffs, or to reach tunnels that look tall
-
of course, you can also make your own entrance to the underground world: dig a vertical shaft in a convenient location (such as the basement of a room), and then start digging horizontally at a suitable height. Usually, this method wastes more tools (because all the channels need to be g by themselves), but with proper lighting, you can hardly see monsters. You may have g a natural cave (in fact, the probability is very high!), At this time, you can refer to the previous skills for cave exploration. There are many different opinions about the optimal mining strategy, but at the beginning of mining, the safest method should be mining 1 × 3 shaft with staircase in the middle to avoid falling. No matter how you arrange your mine, please ensure a certain amount of light to prevent monsters. Of course, when the resources in the cave are exhausted, you can go back to your mine to continue mining

if the building owner thinks it is too troublesome to dig an artificial mine, then the natural mine is a good choice (disadvantages: 1. It's very easy to get lost, so it's necessary to take marks such as sand; 2; 2. There are many monsters, don't try easily without good equipment)

the "rated power" on the air conditioning proct name plate refers to the theoretical value of the power consumption of the air conditioner under the working conditions specified in the national standard, such as the theoretical value of the power consumption of the air conditioner under the refrigeration mode when the outdoor ambient temperature is 35 ℃, the indoor dry bulb temperature is 27 ℃ and the wet bulb temperature is 19 ℃
note that this is only a theoretical value, and the actual power consumption will be greater than this value
in addition, the maximum input power also refers to the theoretical value of the maximum power consumption within the working range specified in the standard
these theoretical values are of little practical significance to users, but provide a platform for procts to compare their quality
the actual power consumption of air conditioning can not be based on this.
The formula is t = 9549 * P / n
P is the rated (output) power of the motor, the unit is kW
denominator is the rated speed, and the unit is R / min
P and N can be found directly from the motor nameplate. Because P n is the rated value of the motor, t is the rated torque of the motor
the power consumed by the motor itself can be calculated by P = I * I * r, which is actually the loss of internal resistance of the motor after passing the current
The external power of motor can not be calculated by simple proct of voltage and current. Generally speaking, motor power is proportional to speed and torque, that is to say, the greater the proct of torque and speed, the greater the output power of motor. The formula is expressed asMotor power = torque * speed * pi / 30
pi is 3.1415926
Extended data:
DC motor has the characteristics of fast response, large starting torque, and providing rated torque from zero speed to rated speed. However, the advantages of DC motor are also its disadvantages. In order to proce constant torque under rated load, the armature magnetic field and rotor magnetic field must be maintained at 90 ℃ °， This is done with carbon brushes and commutators
AC motor has no carbon brush and commutator, so it is maintenance free, robust and widely used. However, in order to achieve the same performance as DC motor, complex control technology is needed. Nowadays, with the rapid development of semiconctor, the switching frequency of power mole is much faster, which improves the performance of drive motor
In addition, in household appliances, such as fans, refrigerators, washing machines, range hoods, vacuum cleaners and so on, their working power is single-phase AC motor. The structure of this kind of motor is simple, so some common faults can be repaired in spare timewhen the motor is powered on, it will not start, the motor speed is slow and weak, the motor shell is charged, the temperature rise of the motor is increased, the motor running noise is large, and the body is overheated
value selection: refer to the relevant technical specifications for line design for specific values, which are different according to the specifications of conctors
in general, it is not required to carry out the breaking force test on the finished stranded wire ring conctor manufacturing, so the breaking force is generally equal to the calculated or rated breaking force
for example, the breaking force of JL1 / g3a-1250 / 70 large section conctor can be calculated as 294.23kn without the support of test data.
