| Abstract: | In order to solve the problem such as fallen column etc.in coal field with electric method,this paper realized the forward modeling of the point current source at 3-D Geo-electric field,and applied the result to the experiment of geology circumstance.The results of the forward modeling and experiment showed that this technique can detect the position of the collapsing column and its water abundance.So we can make use of this technique to guide the production at coal mine. |
