Coal reserves are discovered through exploration activities such as creating a geological map, then carrying out geochemical and geophysical surveys, followed by exploration drilling. Once coal is found it is mined and excavated for use.
coal was discovered by two people digging and then they found coal so then they invented coal and discovered it
When asking the density of a given object, you understand that an object that has a specific gravity (sg) of <1 will sink when placed in water. By processed coal, you may need to see: Bituminous coal (solid): 1346 kg/cu.m. Bituminous coal (broken): 833 kg/cu.m. Anthracite coal (broken): 1105 kg/cu.m. Anthracite coal (solid): 1506 kg/cu.m. The energy density of coal--in other words its heating value-- is 24 megajoules per kilogram. (Note that one kilowatt-hour is 3.6 megajoules.
Coal was likely discovered by early humans who noticed coal deposits on the Earth's surface and recognized its ability to burn as a source of heat and fire. The exact individual or civilization responsible for first discovering coal is unknown due to its ancient history.
Coal was likely first discovered through natural exposure, such as erosion revealing coal deposits on the Earth's surface. Early civilizations may have stumbled upon coal while digging for other resources like metals. Over time, the value of coal as a fuel source became apparent through its combustion properties and energy-generating capabilities.
Crude oil is processed through refining, which involves heating and distillation to separate its components (like gasoline and diesel). Coal is processed through mining and cleaning to remove impurities, then it can be burned or converted into other forms like coke or gas. Both processes can have environmental impacts and require careful handling of waste products.

The Chinese Discovered Coal In 1423 :))))
Anthracite coal was discovered through surface outcroppings and natural erosion exposing the coal seams. Native Americans used anthracite for fuel before European settlers arrived in North America. In the early 19th century, it became an important source of fuel for heating and industry.
coal was created in 19693-06
No single person is credited with having discovered coal, and no precise date of its discovery is known. The Chinese, however, are known to have used coal over 3,000 years ago.

Any of the minerals which are processed in bulk like coal, limestone. gravel.
Two of the regulations for coal mining include:1. The wastes from coal use must be disposed in secure landfill sites.2. The building in which the coal is processed, must have a ventilation system.
Bituminous and subbituminous coals are user to make the pulverized coal for coal burners. This is coal containing the compound bitumen. It is a soft coal. They are graded according to their carbon content. They can be processed into coke before being pulverized.
It is the greatest source of energy discovered.
