SURFACE GEOPHYSICAL METHODS FOR DETECTION OF UNDERGROUND MINE WORKINGS By William J. Johnson and Robert E. Snow – D'Appolonia, Monroeville, PA John C. Clark – Bay Geophysical Associates, Traverse City, MI Abstract Efforts to delineate underground mine workings in the vicinity of tailings impoundments has
Underground surveying embraces the survey operations performed beneath the surface of the earth in connection with tunneling, exploration and construction in subterranean passageways. It is quite different from surveying on the surface. The following peculiarities of underground .
Syllabus for Mine Surveying Part Test 1 Linear measurement: Instruments for measuring distance and ranging, units of measurement in surveying. EDM: Principles of measurement; types, correction and selection of instrument. Angular measurement: Prismatic compass; bearing of lines; local attraction; magnetic declination.
May 18, 2000· While deepening a shaft of an underground mine, it is essential to maintain the verticality of the shaft for the smooth working of cages. The position of the center of the shaft should be known throughout the shaft and needs to be transferred at various levels in the mine.
Mine and engineering surveying are specialist areas of modern day surveying. Mine surveyors measure underground and opencut mines in detail, helping mining companies locate new mines safely. Engineering surveyors work on construction and infrastructure projects to ensure challenging building specifications are met.
In 1995 and 2003, the Mine Safety and Health Administration (MSHA) conducted surveys to determine the number of atmospheric monitoring systems (AMS) that were being used in underground coal mines in the United States. The survey reports gave data for the different AMS manufacturers, the ...
Underground surveying is quite different from surveying on the surface. In tunnelling or mining operations it may be hot, wet, dark, cramped, dusty, dirty and dangerous, and usually most of these. The essential problem in underground surveying is that of orientating the underground surveys to the surface surveys, the procedure involved being termed a correlation .

Most bauxite, iron, and copper ore is mined by open pit techniques, lead and zinc ore are principally extracted by underground mining methods, and precious metals, particularly gold and most notably in the USA and Australia, tend to be recovered in recent years from lowgrade deposits by .
See other formats. Mine surveying is generally defined as the art of making such measurements as may be necessary (a) to determine the location and extent of bodies of coal, ore, etc., (b) to determine the relative positions of points in the mine with regard to each other or to points on the surface.
mine planning and also mine safety. The underground drives or tunnels need to be accurately surveyed and controlled in order to gain the maximum productivity from the mining operation. Peg Survey is the first option in the Mining Application Program and allows the surveyor to carry out a traverse underground to accurately locate the survey stations
Equipment and techniques used in mining and tunneling. Total stations are the primary survey instrument used in mining surveying. [citation needed] Underground mining. A total station is used to record the absolute location of the tunnel walls', ceilings (backs), and floors as the drifts of an
