| 摘 要： | 通过对目前电磁法(主要指瞬变电磁法、甚低频电磁法)用于矿产勘查时所面临的仪器灵敏度、解决地质构造、提高工作效率、提高发射功率等几个问题的思考,认为实际工作中的电磁效应是被噪声干扰了的,与理论上的电磁效应的数据也相去很远,从而造成有用异常与噪声混杂,无法区分.克服这一系列问题的关键就是从仪器上下功夫.应尽快开展电磁法用于中浅部地质构造的研究工作.电磁法不是万能的,却又是可利用的,应引起我们更多关注.以进一步推动电磁法在矿产勘查工作中的应用.

| Abstract: | Some problems remain in the application of electromagnetic methods (T EM and VLF methods) in mineral exploration,involving the sensitivity of equipme nt,interpretation of geologic structure,improvement of efficiency and emission power.The authors consider the galvanomagnetic effect in practice is interfere d by noise.The data of galvanomagnetic effect in practice are much different fr om that in theory,resulting in the mixture of anomalies and noises.The key to s olve this problem is upon the improvement of equipment.The application of elect romagnetic method in the research of shallow structure should be launched.The e lectromagnetic method is not universal,but useful.It should be paid more atten tion in the mineral exploration. |
