How many more years can coal be used, and how many more years can coal be used on Earth?

China's proven coal reserves are only available for mining for 48 years.

It's no problem to use it for hundreds of years

The question of how many years coal can last is influenced by a number of factors. The amount of coal reserves is not clear, and in the mining industry, there is a term called digging and exploring. First of all, the plants of coal ** millions or even hundreds of millions of years ago were buried in the ground after complex geological movements, and the depth of burial varied, so how many years it can be mined depends on the production technology.

The impact of the current in the country, can reach the depth of mining (depth from the ground, the eastern region.

Generally close to 800 meters above the part of the kilometer, the development of the western region is lagging behind, at present there are many new mines, it can be said that the reserves are unknown) is generally about a kilometer, beyond this depth, the problem of temperature and ground pressure will be difficult to solve, plus ventilation, the cost of upgrading is very powerful. Of course, if coal is worth 2,000 yuan a ton, it may be a different matter. This brings us to the second question, cost, which goes without saying.

Based on the above analysis, combined with the current rate of consumption, there should be no problem in 100 years, but the U.S. and India have a high rate of open-pit coal recovery and open-pit mining in developed countries.

Severely restricted, and in recent years, the world's oil market has been on the verge of a serious crisis, so it is only a matter of time before alternative energy sources emerge. Personally, I estimate that there will be a major breakthrough in 30 years, so how long can coal be mined, the question is: When will there be enough or alternative energy?

At the current rate of global consumption, the earth's coal could be used by humans for about 250 years.

We all know that many of the earth's resources are non-renewable, but at least so far we have not felt the depletion of which resources have had a serious impact on our lives, but if we continue to squander like this, our children and grandchildren may not have a better life, even if it is new renewable energy sources such as nuclear energy and solar energy, in order to produce and obtain these energy sources, we also need a considerable amount of non-renewable resources, such as uranium, indium, rare earths, etc.

At present (2010 statistics), there are 1 trillion barrels of proven usable oil reserves on the earth, which can be used for 45-50 years; 120 trillion cubic meters of natural gas, which can be used for 50-60 years; 1 trillion tons of coal, which can be used for 200 220 years. The world's proven reserves of major metallic and non-metallic mineral resources are 145 billion tons. Among them, aluminum can guarantee about 222 years, copper 33 years, lead 18 years, mercury 43 years, nickel 51 years, zinc 20 years, iron ore 161 years.

For now, the remaining reserves of industrial metals are particularly scarce, and will soon face shortages in the next 20 to 30 years, and in terms of fossil fuels, we don't seem to have to worry too much about our children and grandchildren, but this is also based on maintaining the current production unchanged, if humans accelerate the grabbing of these resources, in the future, our children may have to go to outer space to open up living space.

Man is a product of nature, but human development takes place in the destruction of nature. The Earth was born about 4.5 billion years ago, and life on Earth occurred about 3.5 billion years ago. The emergence of human beings is only 3 million years old.

The only recorded civilization of mankind is 6,000 years old. In the long history of human development 300 years ago, human beings and nature were basically able to live in harmony.

However, in the 300 years since the Industrial Revolution, human plundering and destruction of nature has approached the limit of nature's support for human life. According to the current scale of exploitation, oil and gas can be consumed for a maximum of 50 years, and coal can be consumed for a maximum of 100 years; By 2020, most of the earth's mineral resources, including copper, aluminum, tin, zinc, gold, silver, etc., will be mined. Today, the environmental and ecological crisis is already on full display:

The hole in the Antarctic ozone layer is widening; The global climate is changing, and the greenhouse effect is causing the sea level to rise; Air pollution, marine and freshwater pollution, soil pollution, and chemical pollution caused by industrial production are quite serious; The forest coverage rate has been greatly reduced, and the desertification and desertification of land have become increasingly serious. Human disease rates are rising, species extinctions are accelerating, and so on. In short, the earth's resources are declining sharply, the ecological environment is deteriorating, and the conditions for redevelopment and sustainable development are constantly being lost in the rapid development of human beings centered on materials.

According to the research data released by Chinese and Russian scientists, the use of human resources may be more short-lived, and the depletion of your resources will come soon, according to today's coal reserves, it will probably be available for human use for less than 200 years, natural gas will be depleted in 57-65 years, and oil will be the worst, depleted around 2050, so look for a clean, safe, efficient, inexhaustible energy source for us to use, which will be possible to contact the problem of human resources.

As far as the coal is concerned, this should still be used for a few years, but this should be used more and less, because after all, it is equivalent to a non-renewable energy source, so at this time there should be a lot of damage, so it should still need attention.

It's hard to say. If you have it, dig it. If you don't, don't dig it! People. It may not be necessary. It's dispensable! So.

The formation of coal takes at least 1 year or more.

Coal is a kind of sedimentary rock with combustible properties that is accumulated in lakes, bays, shallow seas and other places by ancient plant remains, and transformed into complex biochemical and physicochemical processes. The chemical composition of coal is mainly carbon, hydrogen, oxygen, nitrogen, sulfur and other elements.

Spores, pollen, etc., which are made up of plant cells, can be found in the coal under the microscope, and plant fossils can also be found in the coal seam, all of which can prove that the coal was formed by the accumulation of plant remains. Scientists have found that there have been times when the climate was humid and plants flourished on the earth, such as the Carboniferous, Permian, and Jurassic periods (about 100 million years ago).

The process of formation of coal:

In the Paleozoic Era, 40 million to 50 million years ago, large forests grew on the earth, and with the movement of the earth's crust, a large number of trees were buried in the ground, these trees were isolated from the air for a long time, and under high temperature and high pressure, after a series of complex physical and chemical changes to form black combustible fossils.

Another important feature of coal is the creation of torches, which are indispensable for underground exploration, and while there are other permanent lighting** in the game, none are as easy to obtain and convenient as torches. (You can make 256 torches with a set of coal and 8 pieces of wood, and you'll find a lot of coal as you dig it.) ）

China's proven coal reserves can be maintained for more than 100 years.

China is a country with more coal and less oil, the proven coal reserves account for the world's coal reserves, the recoverable amount ranks second, the output ranks first in the world, the export volume is second only to Australia, China's coal 1000 meters shallow reserves of about 1 trillion tons, including proven recoverable reserves of 114.5 billion tons. Coal is a solid flammable mineral that was gradually formed by ancient plants buried in the ground and undergoing complex biochemical and physicochemical changes. Coal is known as black gold, industrial food, it is one of the main energy sources used in the human world since the eighteenth century, since the twenty-first century, although the value of coal is not as good as before, but after all, for a long time coal is still one of the indispensable energy of our human production and life, coal is also related to the stability of China's industry and even the development of the whole society in all aspects, and the safety of coal is also the most important part of China's energy security.

However, after the coal is stacked for too long, the coal will be weathered, resulting in the oxidation and hydrolysis of the coal molecules, which will reduce the carbon content of the coal and increase the oxygen content, and will also lead to an increase in moisture and a decrease in particle size, so as to make the calorific value of the coal.

It is lowered and is not easy to ignite.

Coal was widely used as a fuel for industrial production and was the Industrial Revolution from the end of the 18th century.

Started. With the steam engine.

The invention and use of coal, coal is widely used as a fuel for industrial production, bringing unprecedented huge productivity to the society, promoting the development of industry, followed by the development of coal, steel, chemical, mining, metallurgical and other industries. Coal has high calorific value, and the calorific value of standard coal is 7000 kcal. In addition, coal is abundant and widely distributed on the earth, and it is generally relatively easy to mine, so it is widely used as a fuel in various industrial productions.

<> coal was formed over hundreds of millions of years, in the entire geological epoch, during the Mesozoic era.

of the Stub and Cretaceous.

The coal-forming plants are mainly gymnosperms, and the main coal species are lignite and bituminous coal, so it seems that the formation of coal is hundreds of millions of years.

Under normal temperature and pressure on the surface, the plant remains accumulated in stagnant water bodies are transformed into peat or saprolite by peatization or saprolite. After peat or saprolite, it sinks to the depths of the underground due to the decline of the basin basement, and is transformed into lignite by diagenesis. When the temperature and pressure gradually increase, it is transformed into bituminous coal to anthracite through metamorphism. Peatification refers to the accumulation of higher plant remains in swamps through biochemical changes.

The process of transformation into peat. Sludge is the process by which the remains of lower organisms are transformed into sludge through biochemical changes in swamps. Saprolite is a silt-like substance rich in water and asphaltene. Glacial processes may contribute to the collection and preservation of coal-forming plant remains.
