| 摘 要： | 针对工程与地质灾害调查要求解决精细构造的问题,投入了近年来广泛应用于工程勘测的回线源瞬变电磁探测。分析了瞬变电磁测深的特点,该方法体积效应小,等值作用范围较直流测深和频率测深窄,故横向和纵向分辨率高。通过2个实例的成功应用,说明回线源瞬变电磁在探测构造破碎带、煤田采空区等方面的应用效果。 |
| 关 键 词： | 回线源 瞬变电磁法 地质灾害 煤田采空区 |

| Abstract: | The small structure survey problems should be solved in the project performance and the geological disaster investigation. The transient electromagnetic method volume effect of loop-source is small. The equivalent action sphere is narrower than the galvanic resistivity sounding method and the frequency sounding. So the transverse and the longitudinal resolution is high. The application of the TEM to detecting the faulted structure fracture zone and the coalfield mined-out zone can yield good effects. |
| Keywords: | loop-source transient electromagnetic method resolution geological disaster |
