GEOPHYSICAL METHODS IN EXPLORATION AND MINERAL ENVIRONMENTAL INVESTIGATIONS by Donald B. Hoover, Douglas P. Klein, and David C. Campbell INTRODUCTION In the following discussion, the applicability of geophysical methods to geoenvironmental studies of ore deposits is reviewed. Details of geophysical techniques are not emphasized; these are covered in standard texts (Society of 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 seams
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) GPR coal seam example pdf. Coal Exploration. Groundwater. Groundwater Investigations. Geophysics can

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
Coal seams can also be evaluated insitu by geophysical means for their coalbed methane content. All of this work can be accomplished by geophysical tools that run inside the drilling rods. page 3. Insitu Coal Deposit Evaluation Methods. Coal deposits occur in sedimentary strata that have some lateral extent. They can also be affected by
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 seams, maps showing the pattern of variation across the area in the earth''s
The geophysical methods which have been used in the reconnaissance, predevelopment, and operational stages of coal exploration and mining are reviewed in terms of their exploratory function and their typical frequency of application. Borehole logging is the one method which is highly utilised for both surface and underground coal mining exploration, although seismic methods (mainly high
It should be noted that coal exploration programs increasingly have become reliant on coaloriented 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 coaloriented logs can provide positive recognition of coal, identification of specific coal beds, and precise coal thickness
Geophysical Methods of Exploration
Modern coal exploration typically involves extensive use of geophysical surveys, including 3D seismic surveys aimed at providing detailed information on the structures with the potential to affect longwall operations, and drilling to determine coal quality and thickness. Mining. Coal is mined by both surface or opencut (or opencast) and underground or deep mining methods, depending
In fact, nearsurface gamma ray logs of cased oil and gas wells are a prime source of data for identifying and measuring the thickness of shallow coal beds in the Northern Great Plains region. The gamma ray logs can detect shale partings in a coal bed
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.
