中文摘要：
瞬变电磁法在采空区调查中得到广泛应用．本文对比了回线源和电性源两种装置在响应特征、探测能力等方面的不同特点，认为回线源瞬变电磁信号对地层灵敏度较高，电性源瞬变电磁探测深度较大．尝试将两种装置联合应用于某变电站选址地层稳定性及周边采空区调查，利用回线源数据可获得浅部地层信息，利用电性源装置探测数据可获得深部地层信息，达到了很好的效果．同时，研究结果认为电性源瞬变电磁法具有探测深度大、施工方便、工作效率高等优点，是一种可用于深部探测的值得推广的电磁方法．
英文摘要：
Transient electromagnetic method（TEM） is widely used for coal mine-out area investigation. In this paper the difference in the response characteristic and detection ability between loop source and grounded-wire source were compared. The conclusion is that transient signal due to loop source is higher sensitivity to earth, and electric wire source TEM signal attenuation has bigger detection depth. This two kinds of devices were combined for in vestigation of stratum stabilty and coal mineout area around a designed power station. The result was satified and the information from shallow and deep stratum had been controlled. The research results also show that the short offset electric source TEM is an alternative device worth to be popularized that suitable for deeper investigation, it has the advantages of greater detection depth, convenient construction, and high work efficiency.
