Prospect of mining industry

1. In recent years, underground mining technology has developed rapidly at home and abroad, and many new mining technologies, new processes, new materials and new equipment have been applied in underground mines. Some domestic mines and a number of advanced mining technology and equipment have entered the ranks of the world's advanced level
according to the above statistics, caving mining is still the main method for underground mining of iron ore, while open stoping and filling mining are still the main methods for underground mining of non-ferrous and gold mines. In the past ten years, the filling mining method and filling technology of underground metal mines have developed rapidly, and the caving mining method and open stope mining method are constantly improved and innovated. Therefore, it promotes the rapid development of underground mining technology of metal mines in China, and makes the technology of some mines reach the international advanced level.

There is only one species of hairy crab, Chinese mitten crab. Bacheng is located in the east of Yangcheng Lake, adjacent to the East Lake of Yangcheng Lake. It is an authentic Yangcheng Lake hairy crab procing area. I eat crabs not only from the procing area, but also from Taihu Lake and Hongze Lake every year. If it's better than crab oil, crab roe and crab paste, other Lake crabs and pond crabs are not so bad, but Yangcheng Lake hairy crabs are really the only one with fresh and sweet taste. It's best to find some reliable local crabs farmers. However, I buy some Tang girl's crabs every year and raise them at home. I'm also close to Shanghai. During the crab season, I drive directly to their house to catch crabs in the purse seine, People who love to eat crabs can't get around Yangcheng Lake

in recent years, more and more Yangcheng Lake crabs have been belittled e to their interests. They all depend on their fame and general taste

responsibly speaking, I go to Jiangsu every year from July to see the crab market, to the Mid Autumn Festival gift certificates, to Lidong and snow gift bags, all of which are involved. The price of Yangcheng Lake crabs is two to three times higher than other Lake crabs

when you ask me if Yangcheng Lake hairy crabs have any brand premium, the answer is yes, and there are many

However, the answer is yes

if you want to taste Yangcheng Lake, you can only buy Yangcheng Lake

3. How can it be accurately calculated, but there are many examples in my side, but not including me, I am not rich, or woodlouse, but the people who contacted bitcoin early are all f rich. Now I have hoarded some bitcoins in Haobtc. I feel that the appreciation space is still very large. You can also buy some stores at a low price. Feel for yourself.

4. At present, under the premise of the bottleneck in the development of the coal instry, the employment prospect of mining engineering specialty has encountered some difficulties, but it is also an opportunity. Mining belongs to the basic instry and will still play an important role in the future. Graates majoring in mining engineering can be engaged in the design and transformation management of coal mines, iron ores, gold mines, gypsum mines and railways. They can also work in the proction and development, scientific research and teaching of six kinds of mining instries, including metallurgy, nonferrous metals, chemical instry, nuclear instry, non metals and coal, and water conservancy, railway, underground, engineering and environmental protection departments. Mining engineering is a major of Geology and mineral resources. It mainly studies and studies the theory and method of deposit mining, and develops new mining technology. In the world, the major of mining came into being earlier than before. During the instrial revolution in the west, it has a long history. China first established the major in China University of mining and technology in 1909

5. Yes, I checked in

6. You don't call it poor computing power, my friend. It should be called sloppy, right? In fact, everyone is the same. Give you a few methods, 1, first of all, we must concentrate on thinking, very seriously treat each problem, after finishing to test again. Of course, the calculation problem to do more time efficiency
draft is very important in calculus
2. Take draft seriously. I don't know how you draft it.
draft can't be too sloppy. A topic should be written step by step. Don't omit it at the beginning.
try to use "circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle, circle It's also helpful to cross out the data you don't want in time.
when the correct rate comes up, you can improve your speed and do more mental calculation.
3. For basic skills, you should practice oral calculation, simple addition, subtraction, multiplication and division, and remember some common numbers, For example, what is the square of each integer from 11 to 19? We remember it in primary school
in addition, we should improve our ability of vertical calculation, especially multiplication and division. Don't laugh. This is the basic skill

how to improve your computing ability

Liu Honghe created in February 2009

in the elementary school entrance examination and all kinds of examinations, calculation questions are involved every time, And the score rate of each calculation is surprisingly low. This phenomenon exists not only in primary school examinations, but also in junior and senior high school examinations. Is the title difficult, or is there another reason? How to avoid losing points in calculation it is urgent to improve students' calculation ability

firstly, it analyzes the causes of students' low computational ability. First, we don't pay attention to calculation, and we are lucky. Many students only ask for & quot; Yes;, Impractical & quot; Solution & quot;, It's even considered a waste of time. Senior examination & quot; History of blood and tears & quot; Tell us, in the exam, the question will be easy to read, but it just can't work out the correct answer. So & quot; Without understanding I think I will be right in the exam. I can't be lucky. Second, students; High conservation & quot; Talk without action. In the process of teaching, the teacher asked the students to carry out calculation training. Many students keep their eyes fixed on the formula and recite words in their mouth. They start to calculate like a computer program, and then report their opinions; Correct & quot; The answer to the question. Many students think & quot; Moving mouth & quot; Compared with & quot; Hands on & quot; Save time, but our calculation is not just the pursuit of speed, but the pursuit of speed under the condition of ensuring the accuracy. Thirdly, & quot; Saving time;, With the help of a calculator. A considerable number of students use calculators, mobile phones and other tools to improve & quot; Work efficiency;, But when the exam is not allowed to bring a calculator, then can only use their own untrained, already rusty head, the accuracy rate can be imagined

how to improve your computing power in a short time< First, abandon the original & quot; Bad habits;, Build good habits. 1、 We should pay attention to calculation, even simple calculation. I have to work out the correct answer to every question. Because 80% of the exam questions need us to calculate the correct answer, so a person's computing ability directly determines the test results. For simple problems, we pursue efficiency; For complex problems, we pursue accuracy. 2、 We should rece | & quot; Self control;, More hands, less mouth. To form a good habit of calculus can not only improve the accuracy of calculation in the examination, but also save our checking time if it is used properly. 3、 Throw away everything that rusts our brains; AIDS & quot;, If you practice your brain, you won't believe that the examination room won't let you take it; The brain

Second, learn to & quot; Calculation program & quot; And pay attention to the simple calculation in the process, many students see the calculation problem, come up dead calculation, until & quot; Count death & quot; until. In fact, facing a formula is like facing a strong man. If you want to knock down an opponent and work out the correct result, you need to find the weakness of the strong man, that is, find the characteristics of the formula, and then take different measures according to the characteristics. After adopting the correct method, we should pay attention to the timely use of simplified calculation methods in the process of operation, especially the basic simplified calculation methods, such as the distribution law of multiplication, the combination law, the rection on both sides of the equal sign and the rection on the numerator denominator, so as to avoid detours< Thirdly, pay attention to the calculation strategy. Generally, we divide calculation into oral calculation, manual calculation and estimation. For simple problems, such as the simple operation between two numbers, we can take oral calculation directly; For the slightly complex formula, we need to do manual calculation; For the following calculation with low accuracy, such as trying to find the range of an unknown number and the integral part of a number in number theory, we can use estimation, as long as we get the result required by the topic; No understanding & quot

fourthly, & quot; Short, flat and fast & quot; A new method of calculation -- evil complement calculation. Time proves that by doing a lot of calculation problems in a short time, students' calculation ability can be greatly improved. Recommend you to do & quot; I love math summer camp -- computing contest; Every year, 25 topics are very representative

finally, we can improve our computing ability by remembering more operation rules and common formulas. Recently, a book "super right brain 19" was found in Beijing Book Building × In fact, it is to let us remember some commonly used formulas and use them flexibly in calculation. Remember some common formulas, we can use the results directly in the exam, which will save more valuable exam time than recalculation. These commonly used formulas are not only used in calculation, but also play an unusual role in decomposing the quality factor and general division

as long as we form good habits, learn to calculate programs, pay attention to calculation strategies, and remember more operation rules and formulas in our brain, we will be able to be extremely brave in the examination room and get the good results we should get

I've been looking for all the above on the Internet for a long time. I hope it can help you and I hope it can be adopted.

7. The advantage of early mining is that it is very easy to improve the mining level
the difficulty is that the later it is, the more difficult it is to upgrade the mining level is mainly a waste of time. It is best for you to dig two numbers at the same time
if you want to dig kuisu, then you should dig it at 30
so that the cost of treatment is the lowest
if you want to dig level 7
then you can only upgrade to 50
generally speaking, it is OK

8. Is to dig coal, sunset instry! No future! Test mining engineering professional look! A lot of people on the Internet are talking nonsense! What mining major has high employment rate, high salary, taking family members, working as mine manager... High employment rate: can it not? Who will do most of the work in three years. The class one year later than us was the worst. More than a dozen people came to our bureau. After less than three years, they sacrificed three of them, which was also bad luck. Two of them were vice leaders of the coal mining team. Now this class has withdrawn except one
2 the salary is high, and I have worked to the section level. Except for welfare and hardware, I got more than 80000, but one day in the valley, most of the coal mines were in the mountains, which was boring. Generally speaking, it's the most difficult period to start with a technician. It's not as good as a worker. As long as you need to write something about ty, technology, business and so on, even if it's the work of a technician in Party building, and you have to go down the well to follow the shift at the same time. More than 25 people go down the well a month. Just like ordinary workers, many of them can't stand it. They all run in this period. Generally, more than 5000 people will go down the well a month! But it's a crime you didn't expect when you were in school. It's not only hard work, but also rough management in the coal mine. After all, most of the coal mines are co workers, which can't be managed by ordinary literati. Those who graated from school may not be able to eat in the coal mine. After all, it's not high-tech. Leaders, like bandit leaders, treat their subordinates rudely and scold them casually! Don't think about it if you want dignity. It's the same when I became a section level. Every morning I held an early morning adjustment meeting. It was just a meeting for mine leaders to scold slaves. I couldn't bear to leave
3 with family members, who do you take. Coal mines are all in the ravine, who would like to come with you, who would like to leave their youth there. It's hard work, overtime every day, high safety pressure and harsh environment. I have been on ty for a long time since I became a technician. I'm on ty for my own shift and for the leaders above. I don't even think about it ring holidays. It's like wearing dirty work clothes every day, staying in the underground without the sun, and going home 2 or 3 times a week (my home is in a small town 30 kilometers away from the coal mine), Some of my classmates are in a more remote mine and only go back once a month! What's the picture! I often ask myself why I didn't learn a craft at the beginning, even a hairdresser or a chef! Now we can only deal with black coal, coal miners and migrant workers every day! But besides, I'm lucky. I've got a good daughter-in-law! It's much better than those who are single now and don't want to find a colleague from their hometown! Some of the people who are looking for their daughter-in-law in rural areas are arranged to go to the miner's lamp room, bathhouse and canteen (leaders can directly go to the authorities). It doesn't matter about the work of dry cleaning coal factory. The coal st is big and dirty, which is not what you can think of. Whose daughter-in-law is willing to do the work
4 you don't have to go to the mine. If you study mining, you can't go there. The employment area is too narrow. If you study mechanical and electrical engineering and geological surveying, you can change your profession. Where are you going. Design Institute? The problem is that they don't want so many people! You can't get along well in the coal mine. Do you want to go to the design institute! If I could, I would have gone already! Who's going down the well
5 when the mine manager, dream! There are several mine managers and deputy mine managers in a mine! In a word, the curtain behind the coal mine network is darker than coal! It doesn't matter if you can do it any more, then you're only tired to death! If you work hard, you won't even be advanced
6 it's impossible to be a billionaire. If you want to be a billionaire, the children of senior officials all over China have come to mining. Your father is the mayor. If not the county magistrate, it's possible. But if you have such a father, you will never be allowed to work in a coal mine
7 higher ecation is popular in coal mines. Not necessarily, some of my colleagues have graate students from the year before last, but they don't have any business! It doesn't matter. The immediate supervisor gives him endless work now, and he doesn't say it's good, so he is deliberately punished. In private, this guy won't come. Qinggao, there's no high technology in the coal mine. It's more than enough to have a college student. You see what my workers do. It's different to have an alt college
8 mining is not popular. Take the sword to the side and win by surprise! It's a mistake! Why is it cold? Nobody does it, so it's cold! The country has not considered this instry well, this instry is the most inferior instry, you want to be famous in this instry, silly dream! I'm sorry to say that I'm a coal miner when I go out! And in order to show a little dignity in front of others, the students working in the coal mine and others are all pretending to be big money, pretending to be generous and boasting. Why? There's only a little self-esteem left
9 the safety of large state-owned coal mines. It's better than a small coal mine! Advanced coal mining enterprises in China and even in the world reported on TV! Not the same, there are accidents, and can be seen on TV are big, sporadic on too much! Coal mine has a safety index called "million ton mortality". Do you know what it is? Casualties per million tons of coal. It shows that it is difficult for coal mines to survive
10. Neither can metal mines. Five of my classmates are working in metal mines. They are also very hard! For coal mines, there is no gas disaster and coal st explosion! Mining areas are deep in the mountains! Four of them haven't found their daughter-in-law now! And I heard that the metal mine has radiation! Bad for people! I bought all the houses in the city, but I come back to live for one or two months every year! However, the work is not as hard as coal mine, the treatment is better than coal mine
the coal mine is hard!

9. Come here to ask about this... It's time for you to hire a lawyer! You can sue the employer who hired you... You are a victim as well as a victim... You can ask him to accompany you for loss
