微动技术在登科地区深部找矿中的应用效果研究

Application Results Study of Micro Motion Technology on Deep Section Mineral Exploration in Dengke Region

为开拓深部找矿新方法,特引入地球物理探测新技术-微动,并探索分析其应用效果。首先介绍微动探测方法原理和数据采集与处理,其次在CSAMT推测的建议钻孔位置开展微动勘探工作,分析单点频散曲线特征,识别深部地层界面;最后根据钻孔验证结果,综合对比CSAMT和微动勘探在深部重点地层界面识别效果。结果显示,微动勘探识别深部层界面效果明显,CSAMT联合微动技术可以提高物探解译的精准度。

New technology for geophysical exploration-micro motion was brought in to explore new methods for deep section mineral exploration and analyze its application results.The principle of micro-motion detection method and data acquisition and processing are adopted,secondly,fretting exploration was carried out at the proposed drill hole location speculated by CSAMT,the characteristics of single-point dispersion curves were analyzed to identify the deep stratigraphic interfaces;Finally,according to the boreholes verification results,the identification effect of CSAMT and micro-motion exploration in the interface of deep key strata is comprehensively compared.The results show that the micro-motion exploration has a significant effect on identifying the deep layer interface,and the CSAMT combined with the micro-motion technology can improve the accuracy of geophysical exploration.
