Coal mining - Prospecting and exploration | …
Coal mining - Coal mining - Prospecting and exploration: The fundamental objective of coal prospecting is to discover coal resources through a search. In areas where coal mining has not been previously practiced, the search process should result in obtaining coal samples that give reasonable evidence of the existence of a coal seam. Once a seam has been discovered, considerable further work is ...

Geophysical Method - an overview | ScienceDirect …
Geophysical Exploration. Geophysical methods have been used for many years in the search for metallic ore bodies and petroleum fields, and are also useful at different scales in many coal exploration programs. If the coal basin is underlain by rocks that are denser than or have different magnetic properties from those associated with the coal ...
Overview on the application of geophysics in coal …
Exploration geophysics is also used to map the subsurface structure of a region, to elucidate the underlying structures, spatial distribution of rock units, and to detect structures such as faults, folds and intrusive rocks. This is an indirect method for assessing the likelihood of ore deposits or hydrocarbon accumulations. Methods devised for finding mineral or hydrocarbon deposits can also be used in other areas such as …
Southern Geophysical Ltd | Exploration Geophysics, …
The requirements for coal exploration are often quite similar to oil and gas exploration, and Southern Geophysical Ltd can provide shallow and deep seismic surveys. Other methods include: Ground Penetrating Radar (GPR) (for shallow targets) Resistivity (for locating burning coal seams)
Geophysics at the Coal-Face: Exploration …
The challenge to coal geophysics is to adapt to these economic constraints and provide cost-effective, reliable methods for exploration and mining requirements. The geophysical methods which have been used in the reconnaissance, pre-development, and operational stages of coal exploration and mining are reviewed in terms of their exploratory function and their typical frequency of application.
