An experiment with the seismic crosshole method in an iron mine

Abstract

Seismic techniques have so far been only sparsely employed by the mining industry for ore prospecting. In the last few years, however, growing attention has been paid to the seismic reflection method which is the most powerful geophysical tool in terms of resolution and depth penetration for hydrocarbon exploration. At least in Sweden there is an increasing interest in geophysical techniques for ore prospecting which allow depth penetration of 1 km or more. The known bodies in Sweden usually dip, however, very steeply, and the standard seismic reflection method will probably have to be modified substantially in order to perform well for such formations.
