浅谈EH4电磁测深法在采空区勘察中的应用

The Application of EH4 Electromagnetic Sounding Method to Coal Goaf Detection

采空区给人类生产生活带来危害,采空区的探测已成为重要研究课题。文章阐述了EH-4电磁测深法的基本原理和工作方法,并结合采空区调查中的应用实例,介绍了EH-4探测采空区的情况,分析总结了采空区以及对应的浅部地层隐伏裂隙带的电性特征并得出结论。结果表明,EH-4电磁测深法能够较为准确地探测采空区异常,为后续勘察和治理工作提供了有力的依据。

Since the goaf can cause dangers of human＇s production and life, the goaf detection has become an important research topic. This paper firstly describes the basic principles and working methods of the EH-4 electromagnetic sounding. Combining with the examples in the goaf detection, this paper also introduces the application of EH-4 to goaf detection, and analyzes the electrical characteristics of goaf as well as the corresponding shallow concealed fractured zone. It reveals that the abnormality of goaf can be accurately detected by EH-4 electromagnetic sounding method, which provides a powerful basis for the subsequent investigation and management.
