Used since the 1880s, coal has been an important staple in human civilisation. It’s been used in the cement and steel industries, as well as in the energy sector to generate electricity. The market for coal has been a lucrative one. And this is the reason coal mining companies, such as Kestrel Coal, have seen significant and sustainable growth in the past years.

But why is coal mining really a lucrative business?

 

Coal Mining: In a Nutshell

 

Mining coal can easily be considered a lucrative business for a lot of reasons. For starters, coal is extracted from the ground in different methods for specific purposes. Specifically, there are coal generation methods for power generation, construction, and manufacturing purposes. This explains why mining companies, such as Kestrel, also explores export markets for their products, aside from their local partners.

 

Uses and Benefits of Using Coal

 

Coal can be used for various purposes. And it is a component of many of the products we use today.

 

For one, thermal coal is used to generate power. Metallurgical coal, also known as coking coal, is best for steel production. It is also used to produce specialised products. Specifically, activated carbon is present in the air and water purification in kidney dialysis machines. Because it is lightweight and strong, it is also used in tennis rackets and mountain bikes. Coal in silicon metal is used to make resins, cosmetics, toothpastes, lubricants, and water repellents. Ammonia gas from coke ovens is used to produce nitric acid, ammonia salts, and other agricultural products.

 

Coal by-products are also ingredients of many household essential, such as dyes, plastics, soap, nylon, solvents, and rayon.

 

Coal Extraction Methods

 

Coal is extracted from the ground in different ways depending on its uses. But over the years, miners and coal experts, such as Kestrel Coal, use two basic extraction methods – Surface Mining and Underground Mining.

 

  • Surface Mining – Also called open cast coal mining, this method is used if the coal seams are just on the surface. There are different techniques in doing surface mining. First is strip mining, which is the process of removing dirt directly on top of each coal seam. Another technique is mountaintop removal mining wherein experts remove the mountaintops to access coal seams and putting the overburden in the nearby valley fills.
  • Underground Mining – If the coal seams are buried too deep, it’s time for expert miners, such as Kestrel Coal, to follow underground mining practices. This practice is used in 60% of the world’s coal producers. This method requires a lot of safety measures because of the need to deploy miners in man-made caves underground to recover coal.

 

In the past, coal extraction requires manual labor, putting a lot of lives at risk. However, today’s technological advancements have made this process a lot faster, more efficient, and safer. Today, hydraulic machines are now used to dig the earth and find coal seams.

 

Coal mining might be a complicated topic for many people. But learning about this lucrative industry is one of the ways you can do to appreciate its uses and presence in our products. Through this industry, the world has witnessed a lot of companies, such as Kestrel, thrive and attain sustainability in business.
