Coal Exploration and Geophysical Logging, with Insitu

It is possible to read a geophysical log and determine with some fair degree of accuracy, the ash, moisture and BTU (British Thermal Units or KiloJoule) value for any seam of coal or any distinctive layer of coal within any seam of coal This capability makes it possible, given the right geological setting, to separate the various grades of coal within a seam and set that seam (or deposit) upMost of these logs are available to the public through commercial companies and may be studied at State geological surveys or at similar agency offices in some States Caution should be used in evaluating and interpreting the existence, thickness, and correlation of coal beds from the geophysical logs of oil and gas exploratory and production wells for two reasons First, if only one type ofCircular 891 Geophysical Logs as a Source of Coal Bed DataAbstract The Role of Geophysics (and this book) Coal mining companies need to overcome the traditional production related challenges of mining costeffectively and of extending the life of their(PDF) A Guide for Applying Geophysics to Coal Mining

Coal reserves are discovered through 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) andIt is possible to read a geophysical log and determine with some fair degree of accuracy, the ash, moisture and BTU (British Thermal Units or KiloJoule) value for any seam of coal or any distinctive layer of coal within any seam of coal This capability makes it possible, given the right geological setting, to separate the various grades of coal within a seam and set that seam (or deposit) upCoal Exploration and Geophysical Logging, with InsituCoal reserves are discovered through 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) andCoal Geology | Geoscience Australia

SURFACE GEOPHYSICAL METHODS FOR DETECTION OF

Mine voids in coal mines are usually encountered as resistivity lows because of the presence of acidic mine water Other Methods, such as magnetics and ground penetrating radar have been used for detecting subsurface cavities, but can be subject to precision, interference, or depth limitations which restrict their use in mining applications Project experience with various surface geophysicalcompilation, surface geophysics, drilling for coal, and the collection and description of drill cores, after which the assessment of coal reserves is discussed In the second part, two basic methods of extracting coal, ie surface mining and underground mining, are introduced Firstly, two main methods—strip mining and openpit mining—of surface mining are discussed In underground miningCoal Exploration and Mining EOLSSGeophysical modeling provides generalized and nonunique solutions to questions concerning the geometry of subsurface geologic relations The nonuniqueness of these solutions is both a mathematical problem and one related to the multiplicity of sources that can cause geophysical anomalies This feature is an implicit uncertainty in the discussion that follows Environmental geophysics, likeGEOPHYSICAL METHODS IN EXPLORATION AND MINERAL

The map shows the location of borehole records containing digital geophysical logs acquired by the former National Coal Board and British Coal during their exploration for coal in the United Kingdom Following the privatisation of the UK coal industry, ownership of UK coal exploration data was transferred to The Coal Authority (CA), who appointed the BGS as custodian of this important nationalUse geophysical exploration tools to assess opportunities to replace coal and wood with cleaner fuels such as natural gas and renewables Evidence links coal and wood emissions to ambient and indoor pollution that can impact respiratory and cardiovascular health 2) Employ geophysical research and monitoring techniques to improve short and longterm anticipation of natural hazards and climateThe Geophysical Sustainability Atlas: Mapping geophysicsgeophysical surveys such as gravity, magnetic and seismic studies Detailed information on coal seam thickness, quality and structure, as well as on the mechanical properties of the rocks associated with the coal deposit and the distribution and quality of the groundwater, are obtained mainly by exploration drilling programs, supplemented by downhole geophysical logging and comprehensiveCoal Exploration and Mining Geology
