Application of 3D Aeismic for Justification and Characterization of Geological and Geophysical Conditions in Mmining Geology

Abstract

Summary The article outlines application of seismic exploration in the field of mining geology in complex geological conditions of Kazakhstan. The justification and characterization of geological and geophysical conditions for experimental 3D seismic surveys implementation for the copper sandstones deposits of the Zhilandinsky group located in the Karaganda region of Central Kazakhstan are presented. The tasks are defined and the methodology of high-resolution 3D seismic survey is developed and tested. Special high-resolution 3D processing and interpretation helped to obtain high-quality seismic materials and to highlight the structural and tectonic structure of study areas, identifying and refining ore-controlling structures, detecting and deep mapping of tectonic faults, volumetric mapping of intrusive bodies. The main keystones during the modeling process based on the results of a comprehensive interpretation of three-dimensional seismic survey together with geological and geophysical data, which will significantly increase the reliability coefficient of forecasting ore deposits, are indicated.
