Abstract
Influenced by topographical and geological conditions, it is difficult for research of mine hydrological geophysics to rapidly and accurately detect passages inducing flooding of mines from water-accumulating abandoned mines, to detect precisely small structures causing flooding of mines. Through the study of the key technical difficult problems of the application of transient electromagnetic method(TEM) in hydrogeological exploration in coal mines, the characteristics of TEM such as sensibility to low resistivity, high transverse resolution and high speed have been sufficiently utilized. New inversion technologies have been used to improve the precision of TEM detection. During many rescues of water flooding induced by water inrush in coal mines, TEM has rapidly and accurately located water-inrushing structures in coal mines. It gains time for emergency rescue in coal mines, has significant social and economical benefits. TEM technology has become an important means for water control exploration in coal mines and has optimistic prospect of application.
