*種方案：接收機1臺,供電銅電極6個,500米電線,200節(jié)1.5v的電池,閘刀開關(guān),不極化電極2個。
一、基本原理

1．接收機
測量參數(shù)：能測量地層剖面不同深度的電阻率PS，通過對不同深度的電阻率分析，可以尋找地下含水層（低電阻率），也能探測地下空洞等（高電阻率）。探測深度從幾十米到幾百米。
2．發(fā)送機
把電池或汽油發(fā)電機發(fā)出的電，變成超低頻方波信號或雙向電流長脈沖向地下供電，建立地下電場為接收機提供地面電場信號。
發(fā)送機的功率大小決定探測深度。
一千二百瓦可以探測50――100米，10千瓦可以探測300――500米。
3．主要技術(shù)特點
（1） 深淺層探測；
（2） 可對探測區(qū)域進(jìn)行多方位、多點位探測；
（3） 可以計算機網(wǎng)絡(luò)形式，對探測區(qū)域進(jìn)行遠(yuǎn)程監(jiān)控和遠(yuǎn)程數(shù)據(jù)傳輸；
（4） 可瞬間一次性完成多區(qū)域、多點位的探測。

二、主要應(yīng)用領(lǐng)域

1．尋找地下水資源
（1） 探測地下1――500米水層；
（2） 用于干旱地區(qū)尋找地下水源；
（3） 用于山區(qū)、平原鉆探水井的定位。
2．探測地下空洞、溶洞等

1. Basic principle
1.1 Receiver
Measuring the parameter: can measure resistivity Ps. of stratum section different depth, analyses through the resistivity to different depth, may look for the underground water-bearing stratum (low resistivity),can even is it wait for to survey the underground cavity (high resistivity)
Survey the depth from dozens of meters to several hectometers.
1.2 Transmitter
Turn battery or petrol electricity that generator send out into ultralow frequency square wave signal or two-way electric current long pulse supply power, set up underground electric fieldoffer the ground electric field signal for receiver .
The depth surveying is determined by The size of power of the transmitter.1200 Watt can survey 50 to 100 meters, 10 Kilowatt can survey 300 to 500 kilometers.
1.3 Main technological characteristic
(1) The depth layer surveying;
(2) Survey that can carry on the diversified, many position in surveying the area;
(3) Can use the network form of the computer; carry on long-range controllinglong-range data transmission in surveying the area;
(4) Disposable survey of much area, many position of completion in the twinkling of an eye.

2. Main application
2.1 Looking for the groundwater resources
(1) Survey 1 to 500 meters of layers of water of underground;
(2) It is arid to be used in the arealook for the underground source of water;
(3) Localization for the mountain area, plain drilling well.
2.2 Survey the underground cavity, cave with stalactitesstalagmites, etc.
