Underground gravity survey in a coal mine [PDF]
Podzemni radovi, 2014 Underground gravity surveys are usually conducted in order to define geological structures and to locate and delineate ore bodies. In the coal mines, on the other hand, these surveys are often applied in solving stability and safety problems of the mine. Basic principals of underground gravity measurements and examples of application in coal mining are
