摘要
为了对未知采空区进行勘察,从而消除安全隐患,在介绍EH4电磁成像系统原理、方法和特点的基础上,简述了EH4系统探测采空区的施工方法、技术及资料处理与解释方法,煤矿采空区探测实例表明,EH4电磁成像系统对采空区有较好的反映,探测效果显著,这也为以后的采空区探测提供了一种可靠手段。
In order to make a survey in the unknown goaf of the mine to eliminate the safety hidden dangers, the paper introduced the construction method, technology, information processing and explanation method of the EH4 system applied to survey in the goal based on the principle, method and features of the EH4 electromagnetic image system. The survey practices in the mine goaf showed that the EH4 electromagnetic image system could have a good reflection in the goaf. Obvious results were obtained from the survey and could provide a reliable means for the future survey in the goal.
