The Industrial RevolutionEarth-shaking changes have taken place in human life. The production of various machines makes us no longer rely on the forces of nature, but we also know that energy will not appear out of thin air, nor will it disappear in vain, but will transform its own form of expression. This is the law of conservation of energy. So the legendary "perpetual motion machine" does not exist, and our machinery also needs to consume energy to run.
And so,EnergyIt is more and more important to human beings. People even start wars in order to compete for energy. To this day, our cities still run on a variety of energy sources, and people are always looking for alternatives to the energy sources that exist in the world and the energy they use today.
If you want to talk about the most important energy in the world now, then no.OilIt's nothing. Black crude oil is like liquid gold, the blood of modern cities. Oil can make fuel, chemical raw materials, we usually useDetergents, cosmetics, pharmaceuticalsThere is also a trace of oil, and it can be said that all aspects are affected by oil extract.
In fact, in addition to oil, human beings are also using other energy sources to maintain the operation of this modern society, includingCoal. Coal and oil are the same.Ancient organic forms of non-renewable energyAnd coal has been used longer than oil.
The role of coal and the history of mining
Coal is a combustible mineral mainly formed by ancient plants in the formation of deposits,It was known a long time ago, but because the demand for fuel was not so great in the pre-industrial era, people did not mine it in large quantities.
China was one of the first countries to recognize the role of coal in the early Warring States period.ShanhaijingSince then, there has been a small amount of mining in various open-pit coal mines, but it has not been able to form a scale. Due to the backwardness of our country in the industrial revolution, we began to use modern technology to mine our coal mines after learning western industrial technology in the late Qing Dynasty.
Coal mines are divided into many kinds, and there are various qualities according to the age of coal formation. Generally speakingThe longer the coal mine is formed, the less impurities in the coal formed and the more fully it burns.And those coal mines that are not pure enough will also produce more pollutants after burning.
Therefore, after mining, coal will go through the refining process of "coal washing" to reduce the pollution caused by coal combustion. According to the depth of coal burial, it is also dividedunderground coal mines and open-pit coal minesAmong them, the mining of open-pit coal mines does not need to be driven too deep into the ground, and can be mined directly by digging the surface.
opencast coal mine in china
China is a vast, mineral-rich country, in which the reserves of coal is quite rich. Around the world.40%The coal mine is shown to the world through open-pit mining, and there are many open-pit coal mines in China.
Compared to underground coal mines, opencast coal mines requireLower technology, lower cost, and more economic benefits. China's more famous open-pit coal mines are mainlyHuolinhe Coal Mine, Yuanbaoshan Coal Mine and Heidaigou Coal Mine in Inner Mongolia, and Antaibao Coal Mine in ShanxiWait. Some of these coal mines have been mined for a long time, even up to a hundred years.
Among the many open-pit mines,Fushun West Open-pit Coal MineIt is an open-pit coal mine with a long history and huge output. It started mining in 1914 and stopped mining in 2019. There are a total105 yearshistory of mining.
Moreover, the mining history of Fushun West Open-pit Coal Mine is also the history of blood and tears and struggle of China's modern industrial development. We can see the struggle and struggle of this ancient country over the past century, our indomitable struggle, and our determination to develop and grow.
This coal mine once belonged to us and was taken away. It once made great contributions to the motherland and became the enemy's "arsenal". Let's take a look at the past and present of this open-pit coal mine.
History of Fushun West Open-pit Coal Mine
Fushun West Open-pit Coal Mine is located in Fushun City, Liaoning Province.One of the largest open-pit coal mines in Northeast China with abundant coal reserves. In the Guangxu period of the late Qing Dynasty, the initial mining of coal began here, but it was later occupied by the Japanese invaders and became an important source of fuel for the Japanese invaders.
According to statistics, during the occupation of the Fushun West Open-pit Coal Mine, the Japanese invaders took a total of close0.2 billion tonsThe clean coal is really shocking. In fact, not only the Fushun West Open-pit Coal Mine was plundered, but other coal mines in Northeast China and more strategic resources were occupied by the Japanese aggressors, suchForest, iron oreWait.
This occupation lasted for 40 years, and the brutal Japanese oppression here made the near250000 Chinese laborLost his life. It was not until we finally defeated the Japanese invaders in 14 years of bloody battles and drove them out of China, that the Fushun West Open-pit Coal Mine was returned to China. But after that, our country is still not completely at peace, so the productivity here has not recovered.
It was not until the founding of New China that we had the opportunity to concentrate on construction, so the Fushun West Open-pit Coal Mine began to be valued again and became an important coal producing area in New China, and the mining volume reached1 billion tonsIt has made an indelible contribution to the recovery and development of China's industry."Sea of Coal".
According to the calculation, the thickness of coal seam in Fushun West Open-pit Coal Mine isBetween 20-150 mThe average thickness of55.5 m, yes.One of the thickest open-pit coal mines in the world.
After a hundred years of mining, a huge funnel-shaped pit has been formed here, like an inverted volcano, which is a concrete symbol of the Chinese people's conquest of nature and hard work. Therefore, Fushun is also called"China Coal Capital", and Fushun West Open-pit Coal Mine has also become"Asia's first open-pit coal mine".
Present Situation of Fushun West Open-pit Coal Mine
However, coal mine is a non renewable resource after all. Even the coal mine with huge reserves like Fushun West Open-pit Coal Mine will be exhausted one day. Therefore, we need to actively seek transformation and not make the local economy too dependent on coal mine.
In fact, since the 1980 s, people have begun to seek the transformation of Fushun Coal Mine, because we have already seenThe resources of Fushun West Open-pit Coal Mine are on the verge of exhaustion. After decades of exploration, we finally found the future development direction of Fushun West Open-pit Coal Mine:The construction of China's industrial history museum, let more people understand that period of history.
The history of Fushun West Open-pit Coal Mine is actually China'sA microcosm of the history of modern industrial developmentIt is also a process for the Chinese people to build a stronger country. From the end of that difficult feudal era, to the modern era of bullying and aggression, to the final establishment of New China, and the difficult development of modern industrial countries, we have paid too much blood and tears.
Therefore, while we enjoy the modern happy life, we should not forget the past struggles of our ancestors. If it were not for their sacrifices, it would be impossible to have today's China. If you have the opportunity, please be sure to visit Fushun West Open-pit Coal Mine and feel the greatness of human civilization.
The future of coal
Although the vast majority of vehicles now do not need to use coal as fuel,thermal power generationWe still have an important place in all the ways of generating electricity in the world, and we have not yet achieved a complete energy transition. Thermal power generation will not only consume a large amount of non-renewable energy, but also bring air pollution, which will bring great harm to the overall environment of the earth.
Ingreenhouse effectMore and more serious today, we have to carry out the energy transition in time. At present, China is actively developing in a variety of clean energy, suchWater energy, wind energy, solar energyAnd so on, these energy sources are renewable energy sources that will be "continuously" produced on the earth.
However, it is foreseeable that we will not be able to completely abandon the mining and use of coal in a short period of time, because the technology for the use of clean energy is not mature enough,We cannot completely replace traditional energy sources.. China's energy demand is very huge, we still have many construction projects to complete, and the people's living standards need to be further improved.
However, according to the current development speed of our country, I believe that we will soon be able to walk in the forefront of the world. Without continuing to mine our country's coal mines, we can better protect our country's environment and protect our country's unexploited resources.
Conclusion
Although human beings have developed civilization for thousands of years, it is only in modern times that we have exploited the earth's resources in large quantities. But it was during these centuries that,The total amount of resources that humans have mined on the planet has reached unimaginable levels in the past..
If this continues with the development of science and technology, the speed of mining resources will be faster in the future, and these energy sources will be completely exhausted in a very short period of time, which is not a good result for human beings who have not yet fully found alternative energy sources.
Moreover, our earth's overall climate has a strong tendency to warm under the influence of human influence, before more serious consequences appear."Timely Stop Loss".
The earth is the only home of human beings at present, and it is an indispensable part of our survival. Human beings who have left the earth's environment will lose everything they have, and the earth's anger will destroy everything.
Even if human beings do not intervene in nature, the natural environment is constantly changing. We are not fully prepared, let alone "accelerate" with our own behavior. Fortunately, today's human beings have understood the impact of their actions on the earth, and will take action in the future to make our home develop in a better direction.
