It means the searching for and the mining of coal. We really already know where there is lots of coal in the world, waiting to be dug up.

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.
they dig mine and maybeonce they have reached 700 to 1,200 feet deep and search soon they will find black rocks from around 5 to 1/2 inch and they will mine it and throw 1 rock in a fire and if it makes the fire biger they know coal is near by
Scientists find coal underground by using a variety of methods such as drilling core samples, seismic imaging, and ground-penetrating radar to locate coal deposits. Once a potential coal deposit is identified, further exploration and sampling are conducted to determine the quality and quantity of the coal present.
Coal is typically found by geologists and mining companies through exploration processes that involve analyzing rock formations and drilling core samples to locate coal seams within the Earth's crust. Once a deposit is identified, mining operations are set up to extract the coal for various industrial and energy purposes.

Yes, coal deposits have been found in Antarctica, but extracting and using them is currently not economically viable due to the extreme conditions in the region. As for oil, there have been limited exploration efforts in Antarctica, but the environmental sensitivity and protection regulations in place make commercial oil extraction unlikely.
Coal can be found on the surface in areas in which the overlying strata have eroded. Coal layers can be exposed in road cuts and on the walls of river valleys. Coal can also be discovered by drilling core samples down from the surface.

It has been estimated that there are over 847 billion tonnes of proven coal reserves worldwide. This means that there is enough coal to last us over 130 years at current rates of production. Coal is located worldwide - it can be found on every continent in over 70 countries, with the biggest reserves in the USA, Russia, China and India. All fossil fuels will eventually run out and it is essential that we use them as efficiently as possible. Coal reserves could be extended still further through a number of developments including: the discovery of new reserves through ongoing and improved exploration activities; advances in mining techniques, which will allow previously inaccessible reserves to be reached. Additionally, significant improvements continue to be made in how efficiently coal is used so that more energy can be generated from each tonne of coal produced.How is Coal Found?Coal reserves are discovered through exploration activities. The process usually involves creating a geological map of the area, then carrying out geochemical and geophysical surveys, followed by exploration drilling. This allows an accurate picture of the area to be developed.The area will only ever become a mine if it is large enough and of sufficient quality that the coal can be economically recovered. Once this has been confirmed, mining operations begin.
