Abstract

Summary

Natural degradation of underground quarries is seen as a major risk management topic in France. The aim of this study is to use resistivity properties of the rock material for assessing underground quarry pillars. It focuses on a quarry pillar (located in the French city of Vendôme), on which two methods were performed. The first one consists in using ERI and photogrammetry to image the internal resistivity of the pillar ; it turns out to be both informative and difficult to carry out (because of its cost and the time it needs to be performed). The other one consists in using a small in-line Surface Resistivity Probe. It proves to be an easier but also less informative method, as it gives only surface resistivity values. Internal and surface resistivity values are well correlated. Both methods show the presence of a very conductive area on which a vertical crack is visible.
