Coal Mining: Benefits, Types, and Uses

Solarglaze | August 16, 2019 | 0

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.

Why you need a hydraulic engineer for your…

Whether you are building a house or are constructing an office building, you should know that you will need more than an architect, a civil engineer, and a construction crew. You will also need a hydraulic engineer. They will help you with things like your hydraulic BIM documentation, to help survey your location in order to implement a proper flow of fluids, and to come up with plans for your structure’s plumbing and sewerage needs.

hydraulic BIM documentation

To further understand why you need a hydraulic engineer, you must first know what they actually do. Some of the terms surrounding their work are pretty technical, like hydraulic BIM documentation, symphonic drainage, and trade waste drainage, to mention a few. What do these mean and what exactly can a hydraulic engineer help you do?

What can a hydraulic engineer do?

To put things plainly, here are some of the things that a hydraulic engineer can do for you:

  • They tell you what your building needs in terms of plumbing and drainage.
  • They are the ones who will tell you if the plans and drawings for your structure’s system of pipes are correct or will need altering for optimum efficiency.
  • Also called a hydraulic consultant, these experts know what can affect the flow of water, what conditions need to be met for specific building designs, and how to address design flaws in your plans.

The technologies used by hydraulic engineers and companies that specialize in designing your plumbing for you include computer aided design (CAD) and building information modelling. With the help of hydraulic BIM documentation using computer aided design (CAD), you will be given a glimpse of how their plans for your building’s plumbing will work. These will give you 3-dimensional views of what will be done for your project when it comes to your plumbing, sewerage, and other piping needs.

With these 3-dimensional designs and walk-throughs, you can clearly see what flaws were present in your original plans and what solutions their hydraulic designer used to address such flaws. The use of CAD and BIM in the creation of plumbing designs for your building will help you to better understand what needs to be done. These include the dynamics involved in creating the right kind of plumbing for your building.

What to expect from a hydraulic consultant

Aside from the aforementioned tasks that a hydraulic engineer does, they also help determine if the plans for your plumbing won’t interfere with other systems. This can mean they will also design and construct plumbing plans from scratch to address problems your original plans had . They will be able to find clashes between systems with the help of BIM and CAD, which will enable them to come up with a better design for your structure’s plumbing and drainage.

If you are in need of such a company or specialist to help you with your hydraulic design and construction requirement, the one company you can trust with this is DMA Engineers. They have people who specialize in all aspects of engineering and these include electrical, fire safety, mechanical, and hydraulic.
