Many people know that gold has a price, but jadeite has no price.

more than 90% of the jadeite in the world comes from Myanmar, a poor country.

the pieces of jadeite raw stones we saw in gambling city,

< P >

prevent others from digging in their own territory

therefore, the jadeite we see has been mined and transported to a safe place,

difficult mining and remote and complex transportation,

the value of jadeite must be very high,

therefore, people who complain that Jadeite is expensive should understand each other,

after all, it is hard won

3. Mining method description:

picking method
picking method is a common mining mode, which is labor-saving. On the surface, it's easy to find some cave entrances. Some of these entrances lead to small caves, while others are connected with complex cave systems. In order to mine the exposed ore in these caves, the picking method is undoubtedly the most direct method. It's actually easy to mine the top of the cave: prepare some dirt, sand, gravel, cobblestone or other easily removed blocks (at least 10 blocks), keep jumping in place and put them under your feet. After mining the ore at a high place, dismantle the base just built and come underground safely - this is very important, especially when the height is very high; Sometimes the base is made of ore instead of discarded blocks. I don't want to waste it. Although the picking method is very simple and labor-saving, its results are not necessarily fruitful. Therefore, there are the following systematic and more effective mining methods. Monsters are often born in caves, so they need to bring Swords (or bows) and food
vertical mining
safety precautions
the most important principle is: don't dig out standing space, because you don't know what's underneath - it may be magma or cave. Be careful of the magma - if you fall into the magma, you will not only die, but also burn things to ashes. So the 1x1 mine is very dangerous. It is suggested to take a bucket and a metal block with you for quick reaction. A block should be used to block the flowing magma to prevent it from flowing into the mine; Pouring water over flowing magma can turn it into cobblestone, and water can also be used to put out fires
mining method
ladder mining
ladder mining is a common mining technology. Using this method, you can quickly reach the bottom of the map and collect stones at the same time. In essence, it allows players to return to the entrance of the mine at any time when they are mining down
since players can only jump up one space at a time, the ladder height can only be one space at most< The most basic strategy is to dig a 45 degree line with the horizontal line ° Angle of the straight-line staircase, each forward one grid at the same time down one grid. To return to the ground, you just need to press the jump button all the way forward
when you have enough cobblestone or wood, you can build steps. Putting these steps in the tunnel can make your journey smoother, more convenient and faster, because you don't have to jump all the time. However, you need to dig an extra square on each step to make room for the steps Idiotic: make complaints about
spiral
spiral stairs may be a bit complicated because there are too many corners. But there are also advantages: it can ensure that the tunnel has been extended downward; Moreover, the gold content of this kind of tunnel is relatively high, which makes your excavation more purposeful. One design is to dig a 3x3 horizontal plane first, and then start digging along the edge of the 3x3 area. Dig one grid down each grid forward, so that there will be enough space when you go down the steps (so that your head will not be blocked). You can choose to leave the pillar in the middle; You can also remove it and put a ladder on the middle frame - but it's not necessary because of the function of spiral ladder
spiral (2x2)
1. Stand in the lower left corner of the 2x2 platform. Dig out the square under your feet. So you can jump up and make complaints about it.
2. Dig out the square in front of it and the square under it, and go down
3. Turn 90 ° When it's dark, put a torch in the wall
4. Repeat steps 2 and 3 until you are satisfied
mine
the so-called mine is a vertical tunnel leading to underground mineral deposits. 1x1 make complaints about the width of the mine. Mines with a width of 4x2 or more can be transformed into water ladders for vertical and rapid transportation
mine with width of 1x2
1. Select mine address
2. Dig out a square next to the one you are standing on
1) go on
2) dig out the square you are standing on and the square below it
3) place a ladder every two spaces
4) go back to step 2.1
3. Repeat the above steps until you need the depth. Then choose a horizontal mining method according to your needs
the mine with waterfall
with an independent descending mine, it's really fast to reach the bottom of the mine; You just jump into the water. The ladder is used to get up. This design needs to prepare 64 ladders and 2 buckets in advance, and then dig a mine with a width of 1x3. One side of the mine is a pool and the other is a ladder. You need to fill in the middle to prevent you from leaving the waterfall when you fall
see vertical mine shaft with water drop for details.
horizontal mining
safety precautions
horizontal mining is not as dangerous as vertical mining. But there are also some similar suggestions. Carry buckets and metal squares with you for quick reaction - a square to quickly block the flowing magma from flowing into the mine; Pouring water over flowing magma can turn it into cobblestone, and water can also be used to put out fires
mining method
branch type
if you want to find rare ore, this is a good way to save labor. Dig down to any depth (usually to the bedrock), and then dig to the outside. The shape is like a tree, with trunk and branches
1. Dig down with the ladder method to find the bedrock
2. Two spaces up, put a square under your feet
3. Dig a 3x3 space
4. Dig a 2x1 straight road, and dig 20 squares to both sides every 4 squares in the straight road
sometimes this method will miss some small-scale mineral resources, which are completely hidden in the branches you open up. But this method is faster, you can get more ore in a short time. If you want to achieve 100% coverage, start digging squares on both sides every 3 squares in the straight
as shown in the figure:
x = straight road (trunk)

straight bar
this method can effectively discover mineral deposits, because it allows you to see all the ores around a certain depth of the tunnel. This method requires excavation on both sides of a 2-grid-thick wall
1. Dig a 7x10x3 room. Keep your steps in the middle of a wall with a length of 10 and an ideal width of 2
2. Starting from the corner, keep level with the wall, dig a 20 grid long tunnel, and insert a torch every 5 grids
3. Dig another 20 grid long tunnel two grids away from the tunnel just g
4. Repeat until you reach the other side of the room

using straight strip mining correctly, you can see all the blocks in a large area, so the ore yield is very high. Two grid wide steps can also improve the yield, because you can see the ore on both sides of the steps. The ideal length of the tunnel is also 20

↑ an example of straight strip mining
Kaogu style
archaeological style is very similar to straight strip mining, which is also to take away all the mineral resources in a certain area. Affirmative, the straight line make complaints about the cube or rectangular tunnel. As far as I know, a cube is a special cuboid...], and it continues to dig down along both sides of the steps“ The name of "Kao Gu Shi" comes from the archaeological sites in the real world. Archaeological mining has to stop when it reaches a huge cave (it doesn't mean it has to stop, but this situation makes it difficult to continue). The excavators have to give up archaeological mining and turn to another project. At the end of the world, the excavation can only stop< The specific implementation methods of archaeological mining are as follows:
1. Determine the construction scale (there is no standard for the scale). However, it is suggested that the scale should be larger, because the taper effect of mineral deposits requires a larger area.)
2. Start digging until the depth of the whole area is 1, and keep a square as a step
3. Continue to dig, deepen the depth by one space, and keep another square as a step. Repeat the steps until the red stone is excavated; Of course, you can stop at any time if you want<

6. There are two types of jadeite deposits in Myanmar: primary deposits and secondary deposits. The primary jadeite deposit in northern Myanmar occurs in serpentinized peridotite. The serpentinized peridotite pluton is 18 km long from north to South and 6.4 km wide from east to west. It is close to the contact zone between the pluton and ultrahigh pressure and high pressure metamorphic rock series, such as glaucophane schist. It extends along a certain direction in the form of dikes or dikes and tilts underground at a certain angle. The primary jadeite deposit is relatively hard because it has been buried under the surface for a long time and has not been eroded and migrated by external geological forces, so it is difficult to mine

the jadeite primary deposits in Myanmar are mainly distributed in three areas, namely, the West and north of leidachang area and longkenchang area. The secondary deposits are mainly secondary placer deposits, which can be divided into two types: the alluvial flat deposits along the wulongjiang river bed and the highland gravel deposits far away from the river bed. The jadeite placers are mainly distributed on both sides of the main channel of the wulongjiang River, and most developed in pagangchang area (locally known as Shuishi), with high quality jadeite

Burma's Jadeite ore is mainly concentrated in the Myitkyina area of northern Burma. The Burma jade ore deposit is divided into 8 large areas according to its geographical location and administrative divisions. This so-called field area is only a division of administrative management, not a division of the genetic types of jadeite jade. Houjiang District, Leida District, Nanqi Xiaochang district. Each field area is further divided into many small "factory Entrances"

Chinese people have loved jade for 8000 years. Confucius, the most holy and forerunner of Chinese people, endowed jade with the beauty of human nature, and almost made a gentle stone the highest realm of life. During the Warring States period, King Zhao of Qin was willing to exchange 15 cities for a piece of jade, which is enough to make people puzzled. Of course, jade in this period mainly refers to nephrite represented by white jade. In the Qing Dynasty, when the crystal clear green stone (Jadeite) from Myanmar entered the palace, a green fashion suddenly rose, and it was out of control“ Jadeite "because it is as clear as spring water, and because of its channeling and moistening, it soon won the favor of the royal nobility, and won the reputation of" emperor jade "“ "Jadeite" is a kind of accumulated national emotion and aesthetic orientation, which is also called "jadeite" when people are full of love for it

the color of jadeite can be divided into primary colors: white, green, purple, black and dark green; And secondary color: yellow, red, etc. Before the 1990s, jadeite was mainly collected and worn by the Chinese in Hong Kong, Taiwan and Singapore. However, the national cultural heritage led to the return of the rich Chinese's love for jadeite. After the reform and opening up, China's pursuit of jewelry has gone through different stages, such as gold, ruby, sapphire and diamond, and now it has turned into jadeite. One of the most important reasons is the "return of jade culture". At the end of 2003, a string of jadeite beads with a price of 1.08 million yuan appeared at the jadeite exhibition jointly held by two jewelry companies, wanruixiang and taiyuanfeng in Beijing Yansha shopping mall, which attracted the attention of all walks of life in Beijing. In fact, such a price is not high for jadeite procts. The world's most expensive jadeite pearl chain appeared in the auction of jadeite jewelry by Christie's in Hong Kong in the autumn of 1997. A string of 27 pure emerald green pearls with a diameter of 1.52 cm to 1.59 cm was formed. A 10 carat diamond clasp is attached to the bead chain. The price of this beautiful jade bead chain is estimated at more than HK $40 million, but at the time of final auction, the transaction price reached HK $72.62 million (the jade bead chain is taken from a 50 kg Burmese jade stone). More than 30 years ago, when a jeweler in Southeast Asia bought this stone, he didn't think it was precious. He planned to sell it, but no one wanted to buy it. Later, the jeweler cut the jade. In the center of the jade was a piece of green jade weighing about 1 kg. So the jeweler made this unique bead chain named "double color". According to statistics, in China, the price of high-quality jadeite has increased 1000 times in the past 50 years< Although jadeite is beautiful, its exploitation is very difficult. There are more than 400 registered jade mining companies in pagan and other areas, but only about 50 are officially mining. Among them, Myanmar Hongbang company, Wenna company, Changlong company, lucky star company and other companies are relatively large. The mining scale is calculated based on the number of excavators, with more than 100 excavators at the most and only one at the least, each with a tonnage of more than 25 tons
the jadeite Placer in the gravel layer of highland is a hill composed of stone, soil and jadeite. Workers first use explosives to loosen the hard place, then use strange hands to excavate and lift it up, and slowly fall to one side. There are several experienced workers in the mping place to select the jadeite jade, and each one has 3-4 people at hand. The selected soil is transported to another place for a second selection, and then the waste soil is transported out and mped. So we dig down layer by layer until the whole mountain is finished. It was thought that jade would be found in every excavation of the strange hand, but it was not. According to the miners, there are very few Jadeites, and it's common that the strange hand can't find them in a few days. What's more, jadeite can only be mined in the dry season, and the dry season is less than half a year. The selected jadeite jade is transported to the place designated by the miner, and is illuminated by experienced people with light. Then, according to the appearance of jadeite jade and other characteristics, whether jadeite jade is useful or not is determined. In this way, part of the jadeite is eliminated. The rest of the jadeite is marked by experienced people, and the workers cut the jadeite according to the line. It is understood that 70% of the sawn jadeite has no economic value, and the jadeite with economic value is less than 30% of the jadeite mined, so it is more difficult to find high-quality jadeite. Some people describe that it is more difficult to find high-quality jadeite than to win the sports lottery

it is not only difficult to find jadeite jade, but also the mining cost is very high. It is understood that there is a jade mining company, there are about 80 strange hands (15% of which need maintenance), about 60-70 can be started every day (the annual useful jadeite mining capacity is about 1500 tons). It takes as much as 5 billion kyat (about 50 million yuan) to spend on explosives, oil, labor and other daily expenses every year. In addition, the mountain road from the mining area to the city is very rugged, and it is impossible to pass in the rainy season, which increases the cost of jade mining. In addition, jadeite is highly scarce, and jadeite is a rare non renewable mineral. At present, jadeite of jewelry grade in the world is only proced in pagan and other areas of Myanmar. With the use of modern mining machinery, jadeite is over exploited, and is facing the danger of depletion, especially high-grade jadeite, which is more and more difficult to find. This makes the price of jadeite procts, especially high-quality jadeite procts, higher and higher. In ancient times, jadeite was only the object of appreciation for the dignitaries and the symbol of status. After entering the 1990s, jadeite began to be active in the field of folk collection. In recent 10 years, the average price of jadeite has increased several times, and some treasures have increased dozens of times. Jadeite art has been listed as one of the important auction items in international and domestic auction. At 1997 Christie's autumn jadeite jewelry auction in Hong Kong, a string of 27 pure emerald beads with a 10 carat diamond clasp sold for HK $72.62 million. At Christie's autumn auction in Hong Kong in 1999, an oval egg faced emerald ring was sold for HK $18.5 million. In the art market in 2004, an emerald carving of shuangfenger, erlongxizhu and niusanzu in the Qianlong period was sold at a high price of 3.85 million yuan at Hanhai autumn auction in Beijing. At an auction in Chongyuan, Shanghai, a string of rare jadeite beads of Laokeng glass germplasm was sold for 1.43 million yuan

however, by analyzing the trend of jadeite market in recent years, it can be seen that domestic collectors pay more attention to jadeite works of art with a long history, while the market of contemporary jadeite jewelry is not very ideal. For example, in the autumn auction last year, China Jiade launched 59 pieces of jadeite jewelry, but only 3 of them were successfully sold, and the auction results were not ideal. However, instry insiders believe that at present, most consumer groups are not in the habit of buying high-end jadeite at auction houses, and professional collectors tend to focus on old jadeite works. Judging from the number of visitors to the auction preview, people's attention to modern jadeite is still increasing, and the market of modern jadeite still needs to be further cultivated

in fact, the value of jadeite is not necessarily judged according to the age. To collect jadeite, we should choose pure natural procts and pay attention to "species", that is, the texture and structure of jadeite. The more delicate the texture is, the more crystal clear the jade is“ "Color" refers to the color, uniform color, color, thick, green for the top grade“ "Water head" refers to transparency, and the luster is crystal clear and transparent, which is the top grade. The so-called "glass type" is the jade with high transparency<

in the 2004 China Jiade autumn auction, the first hammer was a jade Maitreya Buddha Pendant in 18K platinum inlaid with green and fine texture, with diamond inlaid, for 30000 yuan; The second is a jade bracelet with fine texture, good transparency, a little violet color between emerald color and colorless color. The falling hammer price is 40000 yuan; The last deal was a bead chain composed of 35 violet jade beads with pure color and glass luster, with a drop hammer price of 60000 yuan

experts generally divide jadeite into three categories: A, B and C. A-type jadeite is pure natural proct, while B-type jadeite is turbid and opaque e to the impurities in raw materials. Some jadeite merchants use strong acid to soak and corrode B jadeite, remove impurities, and then use high pressure to pour high molecular polymer such as epoxy resin into the tiny cracks caused by strong acid corrosion, so as to fill and consolidate the cracks. The rability of jadeite treated in this way is poor. C-type jadeite is a kind of jadeite that has been dyed. The luster of this kind of jadeite is not bright. If you look at it carefully under the light, the color does not naturally exist in the interior of jadeite crystal, but is filled in the cracks of minerals, showing a network distribution. In addition, there is a kind of B + C goods, which goes through a variety of processing. Among these types of jadeite, only A-type jadeite has value preservation

at present, most Jadeites we see in antique markets and department stores are low-grade Jadeites, with retail prices ranging from several hundred to several thousand yuan. Low grade jadeite has a certain ornamental, decorative value, and a certain value-added space, but the real collection value is high-grade jadeite. In Myanmar, the price of high-grade jadeite is soaring e to the depletion of jade resources for procing high-grade jadeite. In the 1960s, a piece of superior "Laokeng glass" jadeite could be bought for more than 100 Hong Kong dollars. Now it costs tens of thousands of yuan. For super jadeite, the price is even more amazing

Tibetans suggest that in the investment of jadeite collection, those with abundant funds should choose classic complete sets of jewelry or art ornaments as the first choice, and the funds required range from several hundred thousand yuan to more than one million yuan; Small and medium investment

7. Generally, the construction can only be started in the dry season from November to May of the next year

8. The mining time of jadeite raw stone is from September of lunar calendar to April of next year. The rest are in rainy season, with stagnant water in pits and caves. The climate is hot and it is very difficult to live and dig. The best season for jadeite mining is dry season, which is less than half a year

the jadeite proction areas in Myanmar are mostly concentrated in undeveloped mountainous areas. In the deep mountains, there is often no sunshine for a day, and only the path of jade pickers looms in the vast forest. In the primeval forests and high mountains, there are few people and jackals, so many people never come back. Every summer thunderstorm weather, billowing turbid current pour out, the water continuously smoke, smoke to 3 feet high and gather together, people sitting in the boat, can't see five fingers. In addition, the original tools, short dry season, lack of materials, jade mining is extremely difficult

for example, a high ground gravel layer emerald placer is to be mined, because the flood plain sedimentary emerald placer has been basically mined out, and the miner has no ore to mine except for the high ground gravel layer emerald placer which is very difficult to mine

the jadeite Placer in the gravel layer of highland is a hill composed of stone, soil and jadeite jade. Workers first use explosives to loosen the hard place, then use excavator bucket to lift the earth and stone, and then slowly fall to one side. Experienced jade pickers wait at the place where the earth is mped. As soon as the earth falls down, they go up to pick up the jadeite and jade. There are three or four people at the side of each excavator. The selected soil will not be abandoned, but will be transported to a place not far away for a second selection, and the waste soil will not be transported out until it is clean. So we dig down layer by layer until the whole mountain is finished.
