Coal is a combustible brown-black or black-brown sedimentary rock and usually occurs in rock formations consisting of many layers or layers of minerals, also known as mine veins.
Coal is a form of fossil fuel.
The main component of coal is carbon, along with a wide variety of elements, mainly hydrogen, sulfur, oxygen, and nitrogen. Coal is a form of fossil fuel.
Coal was formed by compacted remains of plants that lived in swamps 250-350 million years ago. This was in the Carboniferous period, when primitive animals first appeared on land. Coal formed from the remains of ferns and other primitive animals, covered with mud and buried as a new form of rock. Over millions of years, this material turned into coal.
Today, the same process takes place in peat bogs, where traces of low-lying shrubbery form peat. When peat dries, it burns like coal. In some parts of the world, chlorophyll (brown coal) is mined. The hardest and purer form of coal called anthracite contains very few impurities.
There are several types of coal today, which is a question that receives the attention of the majority of Vietnamese people, especially those who have learned about coal. As noted, at present, coal is used a lot, including 3 main types : peat, bran coal and lump coal. However, each category has different divisions:
In general, there are many different types of coal on the market today. Depending on the intended use, users have appropriate options. Depending on the information about the types of coal, the user can answer the question what is coal.

When learning about coal, it will be remiss if you ignore the use of coal. There are many people who know that coal is an important fuel. However, not everyone knows much about the benefits of this product. So what is coal, what are the uses of coal, let’s read it below:
It is undeniable that coal is an energy used a lot in production and life. Coal can be used as fuel for a number of industries as follows: thermal power industry, metallurgical industry, food technology.
With the strong development of science and technology, coal is also used a lot to create new compounds. Among them are some outstanding new compounds such as plastics, artificial fibers. In addition, coal is also used as electrodes for civil electrical equipment serving human life.
Coal tar is an active substance that has the property of absorbing toxins. In addition, they also have a great effect in keeping gases, vapors, and solutes in solution on the surface. With these features, coal is considered an important fuel in making water filter materials. In addition, they also support the whitening process of cane sugar or make gas masks used in toxic industries.

Pencil is a very familiar learning tool in human life. However, not everyone knows that pencils are made from coal. The process of making pencils from coal is simulated in detail below:
Undeniably, coal effectively supports economic development. However, that is not the only use. Coal is also used in art, especially in painting. The lead-colored fine art paintings created and displayed to players are mainly made of coal.
People often use coal powder (mainly coal powder created from incomplete combustion of coal) to create color. Specifically, the colors for cosmetic products such as eyeshadow, mascara, lipstick, eyeliner, etc.
Besides the above applications, coal also has a number of other applications such as fuel and fuel for people’s daily lives. It can be said that coal has a very important effect in life.
The application of coal in human life is very diverse. However, besides the positive uses, coal also brings many negative effects. So what is coal, why does coal bring harm? Let’s take a look at some information about the negative effects of coal right below:
Coal is produced and used coal with a large amount of water. That is the reason why the product affects the water used by humans. Water is an indispensable thing during coal mining, cleaning and storage. In addition, the energy production process will also affect the surrounding water.

Many people wonder what coal is, why does it pollute the air? In the simplest terms, coal is a fossil fuel composed mainly of carbon molecules. During the formation process, harmful gases such as carbon dioxide, hydrolytic compounds, sulfur dioxide compounds or nitrogen oxides will enter the air. These compounds do not decompose causing air pollution.
The process of mining, producing and using coal not only affects the environment and ecosystems, but also directly affects human health. For example, when people use coal for heating, the toxic gas CO will be released in the process. This toxic gas will enter the user’s body and pose a danger to human health.
In addition, the use of cosmetic products extracted from coal often has many side effects. They can easily lead to phenomena such as dermatitis, clogged pores, … Especially more severe can cause skin, lung and liver cancer, …
