天然电场选频法是以天然大地电磁场作为工作场源 ,测量天然电磁场在地面上产生的电场分量 ,它检测到的信息包括静态信息和动态信息两部分。动态信息反映的是地下电磁能量的载体 (电磁流体 )的变化规律及变化范围。经过对石下江矿区注浆堵水工程实际应用验证 ,利用其方法确定的地下迳流通道位置准确 ,检查注浆效果快速直观
The natural electric field frequency selection method takes the natural earth electromagnetic field as the working field source and measures the electric field component generated by the natural electromagnetic field on the ground. The detected information includes two parts of static information and dynamic information. Dynamic information reflects the underground electromagnetic energy carrier (electromagnetic fluid) changes in the law and the scope of change. After the actual application of the grouting water block project in Shijiajiang Mine, the method of determining the location of the underground chute flow channel is accurate, and the grouting effect is inspected quickly and intuitively
