【摘要】 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更多还原

【Abstract】 The self potential frequency method is an A.C.electric prospecting technique which makes use of the natural telluric electro magnetic field as the source of electric potential.The received information involves static and dynamic information.The dynamic part reflects the changing rule and the range of the electromagnetic fluid.The test grouting at Shixiajiang coal district shows that the zone of groundwazter runoff prospected by the said method is right and the examination to the grouting is efficient.更多还原
