Интересные факты про Уголь

Coal has been closely linked to human life since ancient times. This fossil fuel was one of the first to be used as a source of energy. The use of coal in metallurgy and chemical production provided a powerful boost for technological development. Coal was formed in the distant past. Plants trapped without oxygen did not rot, but turned first into peat, and then into coal. Coal, in turn, over many years and under the pressure of deep crustal processes, turns into graphite. In mines, the extraction of coal releases many harmful gases that are dangerous to people. In the past, before the invention of gas detectors, live canaries were brought into mines. If the bird became ill, it meant harmful methane had built up in the air and it was time to leave quickly. Did you know that the oldest, still-functioning mine is located in the Netherlands? Coal extraction there began as early as the year 113. Interesting ancient artifacts are often found within coal seams, such as old jewelry or parts of ancient structures. The hardest variety of coal is considered to be anthracite. It possesses a distinct metallic luster. The world's main reserves of anthracite are located in Russia. By rough estimates, our anthracite coal will last 270 years, with our country holding about 30% of all global reserves. Surprisingly, black and rather soft coal and the hardest mineral on earth, the diamond, share the same base substance: carbon. The difference lies in the arrangement of atoms within the substance's structure. Scientists have learned to create artificial diamonds by subjecting coal to high temperatures and extreme pressure. Coal is used to create excellent fuel that rivals petroleum. It is also used to produce naphthalene and a range of other aromatic compounds. That is all for now.
