| 摘 要： | 本文根据大量实验结果,对岩、矿石在受压破裂时产生的电磁辐射性质做了描述与归纳。含有石英与金属硫化物的矿石,在破裂过程中可以产生主频谱500kHz～1MHz的具有独特波型的电磁辐射信号,在更高或更低频段的信号特征则与其它岩石类相似。因此,震源电磁辐射法用于找矿是有一定物理前提的,亦存在识别非矿引起的干扰信号问题。 |

| Abstract: | According to abundant experimental results, this paper has described and summed up properties of electromagnetic radiation produced during the rupture of rocks or ores under pressure. In the process of rupture, ores that contain quartz and metallic sulfides can produce electromagnetic radiation signal of unique wave form with frequency spectra 500 kHz～1 MHz; nevertheless, signal characteristics at higher or lower frequency spectra are similar to those of other rock types. Therefore, the application of seismic source electromagnetic radiation method to ore prospecting is based on certain physical prerequisties and also suffers from the interference signal caused by barren bodies. |
| Keywords: | rock and ore process of rupture electromagnetic radiation seismic source electromagnetic radiation method |
