摘要
Abstract
In order to rationally mine the large amount of rich metal ore resources existing in the rock body,and avoid the harm caused to the nature by the long-term irrational mining method.Therefore,the study introduces the transient electromagnetic method based on double hollow zone,which improves the accuracy of traditional metal ore detection and solves the problem of water accumulation in the hollow zone of the mine.The results show that with the diffusion of electromagnetic field,the resistivity of 25m performs best in the time range of 0.1～1.8ms.The variation of electric field strength with geotechnical depth slows down significantly after the time reaches 0.5ms,and the electric field depth in the range of 3.95～6.09ms has a significant increase in two places,4.3ms and 5ms.The proposed method can effectively identify the empty mining area,which provides a solid foundation for the rock and soil to get the metal ore being accurately identified.关键词
