Research status and development thinking of underground geophysical exploration techniques for metal deposits

近10年,金属矿地下地球物理勘查技术在新方法、新技术、仪器研发、综合与集成和数据处理解释等方面取得了突破性和创新性成果,应用示范与推广效果显著;井中激电、井中TEM、地下电磁波CT、井中声波CT、井中磁测、金属矿测井及其方法组合技术体系已具规模,并取得了突破性进展。文中提出:应加强井下地震技术的研究与应用;开展地下电磁波相位层析成像的研究;加快轻便化地下物探(含测井仪)综合工作站的研制与完善;强化地下物探的综合应用;大力发展磁取样和核取样分析技术;进一步开展地下物探技术向大探测深度,大水平探测距离的关键技术攻关,增强综合研发与应用的力度,形成多方法、多方式组合、综合分析与解释一体化集成技术体系。

Over the past decade, underground geophysical exploration techniques for metal deposits have gained breakthroughs and innovative achievements in terms of new methods, new techniques, instruments development, comprehensive integration, data processing and interpretation, the application and generalization effects of which are remarkable. The technique system of borehole IP, borehole TEM, underground EM wave CT, borehole acoustic wave CT, borehole magnetic survey, metal logging and their combined methods have developed to a certain scale and obtained dramatic breakthroughs. This paper proposed the following viewpoints:we should strengthen the research and application of borehole seismic techniques, get down to study about underground EM wave phase tomography, speed up the development and improvement of portable underground geophysical integrated workstation (including logging instrument), enhance the comprehensive application of underground geophysics, strongly develop magnetic sampling and nuclear sampling analysis techniques, strive to further develop underground geophysical techniques for great-depth and great horizontal distance detection, enhance the comprehensive development and application degree, and form an integrated technique system with multi-method, multiple work modes combination, comprehensive analysis and interpretation.
