CiteSeerX Document Details (Isaac Councill, Lee Giles, Pradeep Teregowda): Coal exploration projects are focused to accurately predict the geology of a coal field in a costeffective manner. More geologic data generally yields a better geological model of the coal field. Advances in geophysical methods may provide tools to supplement traditional methods of coal exploration.

Geophysical and remote sensing technologies have become essential to the discovery and assessment of gold and silver, base metal, coal and uranium, and strategic mineral deposits. Airborne geophysical methods are employed to map large areas and increase the efficiency and success of the exploration program. Ground and borehole geophysical methods are deployed to map the subsurface geology.

The focus of these coal exploration projects are to accurately and cost effectively predict the geology of a coal field. More geologic data generally yield a better geological model of the coal field. Advances in geophysical methods may provide tools to supplement the traditional methods of coal exploration.

Latest trends in seismic coal field exploration. Journal Article Arnetzl, H H World Coal; (United States) Applied geophysics in the form of seismic exploration for coal fields in West Germany is discussed. The vast amount of threedimensional seismic data obtained during exploration .

In coal exploration, the geophysical logs are not only used for identifiion of coal beds, but are also successfully used for coal quality estimation. ... The borehole geophysical methods are ...

Sep 13, 2019 · Exploration geophysics is the applied branch of geophysics which uses surface methods to measure the physical properties of the subsurface Earth, along with the anomalies in these properties, in order to detect or infer the presence and position of ore minerals, hydrocarbons, geothermal reservoirs, groundwater reservoirs, and other geological structures.

Geohysical well logging. Geophysical well logging (borehole logging,) is a set of borehole investigation methods that are based on special logging tools.. First developed in the beginning of the 20th century, well logging comprises today several tens of methods that involve measurements of natural or induced physical fields in the borehole.

This book aims to provide nonexperts with a better understanding of those geophysical methods that are considered as most likely to be applicable to commonly occurring coal mining problems ...

ADVERTISEMENTS: The following points highlight the two main geophysical methods of soil exploration. The methods are: 1. SeismicRefraction Method 2. Electrical Resistivity Method. 1. SeismicRefraction Method: The seismicrefraction method is based on the principle that elastic shock waves travel at different velocities in different materials. Shock waves are generated at a point on the ...

As part of the first year's project an investigation into the applicability of gravity and transient electromagnetic geophysical methods for coal exploration was undertaken. The Caroona coal prospect has a resource of high quality multiseam coal lying within relatively complex geology. While significant drilling has been undertaken in the area ...

Although these geophysical methods are very crucial for gold exploration, geochemical methods – including portable xray florescence(XRF) – remain as the only methods that can measure concentration of gold and other associated elements. Gold is mined as a primary product or as a byproduct from a wide range of deposits.
