The History of Mining

Mining has long been a part of human civilization. Going back as far as 3,000 BCE, humans have been adept at exploiting the resources of the earth for their benefit. From the Bronze age through the Roman Empire, and across hundreds of cultures, taking resources from the ground became not only a way of life, but something that was essential for societies to grow and stay ahead of their competition. While the tools and methods of extraction have changed vastly over the millennia, the purpose of mining has remained the same.

In the Bronze age, humans had already started panning for gold and other precious metals. This was done by placing large amounts of sediment in a pan and sifting it through repeated cycles of adding water and shaking the pan until only the gold was left. This level of mining was done extensively in Ancient Egypt and Mesopotamia, and these civilizations used the precious metals to create jewelry, artwork, and to have great wealth.

By the time of the Roman Empire, a more advanced type of mining was developed. Using tunnels and digging deep below the surface of the earth, they extracted large amounts of copper, iron, and other minerals to create tools and weapons. While this form of mining was not without danger, it allowed the Romans to create large, sophisticated cities and infrastructure.

With the development of technology and the discovery of new types of minerals, humans were able to expand their reach even further when it comes to extracting resources. With gold being found on almost every continent in the world, it is easy to understand how the 16th century saw a massive influx of gold, starting with Columbus’ discovery of the New World. As steam engines and dynamite became increasingly used to dig deeper, more efficient mines could be created, allowing for an even bigger scale of resource extraction. By the 19th century, coal and other minerals were also being heavily mined, creating great wealth for those that had access to this resource.

Today, mining is still essential to many aspects of our lives. Whether it is coal to power our factories, gold to make jewelry and electronics, or oil to fuel our cars, we are all dependent on the resource extraction industry. Modern day mining is more efficient, safer, and less tedious than ever before, and while it has evolved since the days of Ancient Egypt, the purpose and end product remain the same.

Coal is a fossil fuel extracted from the ground. It is a complex mixture of organic compounds of carbon, hydrogen, oxygen, nitrogen, and other elements. Coal has been used for centuries for heating and cooking, but it has become more and more important as the main energy source powering industrial processes since the Industrial Revolution.

It is estimated that the total amount of coal reserves worldwide will last for another 150 years. While some of the use of coal is reasonably efficient, much of it is still wasteful and harmful to the environment; the burning of coal releases large amounts of carbon dioxide, as well as other pollutants, into the atmosphere.

Not all types of coal are created equal. The type (or rank) of coal is determined by its carbon content and hardness. Lignite is the lowest rank of coal and is the type used primarily in power plants, while high-rank coals releases more energy when burned. Bituminous is the next higher grade, anthracite is the highest quality.

There are many different methods of extracting coal from the ground. Underground mines exploit deposits of coal that are too deep to be extracted from the surface; these often require complex networks of tunnels, ventilation systems, and safety equipment. Mining of coal can have significant impacts on the surrounding environment, with air, water and land pollution being of particular concern.

Overall, coal as a natural resource continues to be an important source of energy for many countries. However, various forms of renewable energy, such as wind and solar, are slowly becoming more popular and efficient alternatives to using coal.
