- electromagnetic applications in mining
Application of electrical and electromagnetic techniques in mining conditions, i.e. for surveys conducted directly from excavations and/or shafts, was presented in mining and geophysical confer-ences, but relatively seldom in the geophysical lit-erature (Cook 1977, Verma & Bhuin 1978, Goszcz & Marcak 1986, Turner et al. 1989, Kotyrba & Ko -
2008-11-24 Electromagnetic measurements are performed either in the frequency domain(FEM) or in the time domain (TEM). Instruments for FEM are designed to per-form investigations for mining engineering and ground water prospecting. TEMmeasurements are conventionally designed for deep targets, but recently thereare instruments that can be used to explore shallow sources (20-500 m)
Mining engineering safety detection plays a very important role in mining engineering.

China ABSTRACT Coal and methane outburst are catastrophic in coal mining, their prediction is difficult.
2015-4-29 Magnetic separation is most commonly used in the mining industry to separate “tramp ore,” or unwanted waste metals, from the rest of the bulk material. Tramp ore typically consists of the man-made byproducts created by the mining process itself, such as wires from explosive charges, nuts and bolts, nails, broken pieces from hand tools such
Geophysical techniques have wide range of applications mainly in earth science, marine science, civil engineering, hydrology, archeology (Teixidó, 2012)and Forensic Science. For example in earth science they are used and applied in Geology, Mining Engineering activities, and Petroleum Engineering. Historically, geophysical technique (magnetic
