摘要
通过阐述井下电法超前探测原理及井下全空间影响因素 ,从提高探测准确度着手 ,提出了三点—三极超前探测方法、施工技术、解释方法。其特点是能避免掘进头后方巷道及层状地层电性变化的影响 ,突出巷道前方的地质异常 。
To increase the survey accuracy,the3points- 3poles lead survey method,treatment techniques and explanation method are presented,through demonstrating the electrical lead survey principles and factors impacting underground safe space.The survey methods are characterized by avoiding the impacting of roadway behind the driving and the electrical changes of bedded strata.
