Abstract

Summary: The main objective of this study is to present the value of multi-hole borehole images interpretation in unlocking the structural configuration of the rock mass in a quick, yet effective way. This analysis revealed that the block is a small fold with moderately dipping limbs with a rock sequence of four main rock types or mechanical units. Fractures are developed only in one particular rock type showing the full control of mechanical stratigraphy on fracture/joint distribution. A fault gouge/broken zone was also identified and correlated in all three boreholes. These results were used to build a conceptual 3D model of the block accommodating both structural features and geotechnical rock types. This which was performed in only 2 days after the data acquisition can be used in any mining process particularly those requiring geological settings understanding of a specific location.
