Detection of tectonic fault patterns for rock mass permeability prediction

Authors: Shevchenko M. D.

This paper presents a case-study of tectonic faulting orientation sensing in strong rock mass. Of particular importance are tensile zones formed as a result of the intersection of multidirectional faults and faults of different kinematic types. They contain much water and are promising for the construction of borehole water intakes. During the study of hydrogeomechanical laws of the filtration structure formation in rock mass, the structure-andgeomechanics model of the test area was analyzed. The model is the result of field geophysical survey conducted at the site earlier by the Geomechanics Department of the Institute of Mining, Ural Branch of the Russian Academy of Sciences. Based on the results of the studies, a rose diagram was constructed. The diagram shows the spatial orientations of different kinematic type faults, with indication of strike azimuth and the maximum principal stress direction. The presented method allows detection of the areas with high water content, which can greatly facilitate mining performance, improve operating safety and significantly minimize the cost of field dewatering during well water intake construction.

Keywords: tectonic faults, hydrogeomechanical studies, well, underground excavations, mine, maximal principal stresses, drainage, faults, stress–strain behavior.
