Abstract
The environmental recovery of former mining areas and communities is an economical activity of increasing importance. Among other aspects such activity must include careful planing and an accurate knowledge of the positioning of old mining works. Frequently these works were conducted underground; very often the location of these works is very difficult because of their complexity as well as lack of information. Thus Geophysics can be very helpful both in their location and in the study of their influence on subsurface geological formations.
