advanced techniques coal exploration

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 necessary in order to advance knowledge of the particular geologic aspects and the extent of the coal deposit

Contour strip mining Contour mining is commonly practiced where a coal seam outcrops in rolling or hilly terrain Basically the method consists of removing the overburden above the coal seam and then starting at the outcrop and proceeding along the hillside creating a bench around the hill

An introduction into the techniques used for subsurface exploration and delineation of coal deposits

A variety of geological techniques is used in coal exploration is including field mapping interpretation of air photos and satellite images and airborne and ground geophysical surveys such as gravity magnetic and seismic studies

Coal mining Coal mining Choosing a mining method The various methods of mining a coal seam can be classified under two headings surface mining and underground mining Surface and underground coal mining are broad activities that incorporate numerous variations in equipment and methods and the choice of which method to use in extracting a coal seam depends on many technological economic

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

The US coal industry serves a vital role in the nation’s economy by producing fuel for more than half of its electricity Despite the industry’s importance industry financial data for 2005the strongest year for the coal industry in recent yearsshows that it is a relatively small industry with revenues totaling 20 billion to 25 billion and net income between 1 billion and 2

completed under the Coal ST Grant in the area of exploration techniques Efforts have been made through sustained RD work mainly at CMPDI to enhance both the pace and accuracy of coal exploration for improved geological modeling of the coal resources of the country Many of the exploration techniques introduced through these RD efforts

Even with detailed advanced exploration at closely spaced intervals mining operations have been affected by many problems such as gas outbursts water inundations dangerous strata conditions and severe operational problems that can result in injuries to personnel as well as major losses of equipment and decreases in production

Geophysical techniques used for petroleum exploration utilize equipment to measure such things as electrical currents gravitational and magnetic anomalies heat flow geochemical relationships and density variations from deep within the earth Each technique records a different set of characteristics which can be used to locate hydrocarbons

technology in coal exploration The geophysical well logging techniques provide detailed records of lithological units encountered in the boreholes thus identifying the coal seams and thickness of each horizon correlation is useful in coal exploration or related formation which continues to be present in

Dec 13 2018 · View the complete article here By its very nature mineral exploration involves drilling to discover what is below the surface While there have been a number of advances in drilling technologies in drilling techniques in the petroleum and geothermal sector in mining there have been no significant advances in mineral drilling technology for decades

Oct 17 2019 · 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 As mining progresses from the initial exploration phase to the latter stages of exploration and into production a higher level of detail about the site
