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.
三维地震在矿山地质物探地质条件判别与表征中的应用
概述了地震勘探在哈萨克斯坦复杂地质条件下采矿地质领域的应用。介绍了对哈萨克斯坦中部卡拉干达地区Zhilandinsky组铜砂岩进行实验性三维地震勘探的地质和地球物理条件的论证和表征。定义了任务,开发并测试了高分辨率三维地震勘探方法。特殊的高分辨率三维处理和解释,有助于获得高质量的地震资料,突出研究区构造构造,识别和细化控矿构造,探测和深部构造断裂,侵入体体积成图。在三维地震调查综合解释结果的基础上,结合地质和地球物理资料,指出了建模过程中的主要关键,这将大大提高预测矿床的可靠性系数。
