Coal Mining Authorizations | Alberta Energy Regulator

A coal exploration program (CEP) is required for exploration activities on public land; Under REDA, the AER is responsible for reviewing Water Act applications and submissions related to Alberta's energy resource industry. Under the Water Act, the AER reviews applications and submissions related to the development of energy resources. The AER ...

Coal Exploration

Coal exploration activities to discover coal reserves include creating a geological map of the area, carrying out geochemical and geophysical surveys and exploration drilling. The mining operation only begins if the coal can be economically recovered. As per the BP statistical review, the world coal reserves are estimated to be 1035 × 10 9 t (1035 billion …

Coal | How revenue works | Natural Resources Revenue Data

Exploration is the process of discovering the specific location, quantity, and quality of natural resources on leased land. Exploration typically takes place after leasing. In some instances, exploration by multiple parties occurs before leasing to increase competition during the lease sale. To apply for a Coal Exploration License, companies ...

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.Depending …

Coal: exploration, reserves, and utilization

The origin of coal has been stud-ied for over a century, but no one has identified a model that can predict the occurrence, development, and type of coal, or provide a satisfactory …

Drilling Methods Used in Coal Mines | Geology for Investors

Additionally, exploration drilling is used to identify or confirm the location of faults, folds, dikes, sills, and other geologic features that may influence how the coal is ultimately mined.
