山西煤田面积占全省面积的37%,公路建设通过煤炭采空区不可避免,如何用有效方法确定地下杂乱的采空区分布是公路建设遇到的常见问题。双源大地电磁测深法测量使用EH4电磁成像系统,其自动采集和处理数据的物探成像仪,具有不受高阻层屏蔽影响、性能稳定、操作方便的优点,文章通过EH4电导率成像仪在确定煤炭采空区的物探实例及效果分析,说明该方法适合浅层地质勘探,是确定煤炭采空区的有效方法。
The area of Shanxi coalfield accounts for 37% of the total area of the province, and road construction is inevitable through coal gob. How to determine the underground messy gob area with effective methods is a common problem encountered in highway construction. Dual source geomagnetic sounding method using EH4 electromagnetic imaging system, which automatically collect and process data geophysical imager with high impedance without shielding, stable performance, easy operation, the article by EH4 conductivity imager in the The geophysical exploration example and effect analysis of the coal mined-out area confirm that the method is suitable for the shallow geological exploration and is an effective method to determine the coal gob area.
