The coal mining life cycle
Exploration. Coal exploration includes gathering data, which allows for decisions to be made on the desirability of further exploration, the technical feasibility of mining, and economic feasibility – including the size of the mine and the quality of the coal. Geologic mapping, aerial photography and photogrammetry are all used in exploration.
Circular 891
It should be noted that coal exploration programs increasingly have become reliant on coal-oriented geophysical logs, which provide important data on thickness, depth, and correlation of coal beds, and locally on the composition of coal. A carefully chosen suite of coal-oriented logs can provide positive recognition of coal, identification of ...

Coal | Properties, Formation, Occurrence and Uses
Coal is a non-clastic sedimentary rock. They are the fossilized remains of plants and are in flammable black and brownish-black tones. Its main element is carbon, but it can also contain different elements such as hydrogen, sulfur and oxygen. Unlike coal minerals, it does not have a fixed chemical composition and crystal structure.
Determination of coal layers using geophysical well-logging …
The most commonly used well-logging methods for determining coal layers are radioactive (gamma ray, neutron and gamma–gamma) and electrical (resistivity, spontaneous potential and inductive polarization). Other methods that can be used are sonic, thermal, density, caliper and dipmeter logs. In the determination of the coal beds, …
