Abstract

In order to grasp the rule of mining transient electromagnetic multi-components characters, numerical modeling methods are employed to simulate the advanced prospecting multi-components response characteristics of gob water with measuring-point arrangement of fanned shape. Results of numerical modeling indicate that there really exist anomaly response in the profiles of induced electrical potential for the case of gob water in front of roadway head. Where the amplitude is highest in the direction of 90 degree for the vertical component, however the results of horizontal component exhibit double peaks abnormality and the amplitude is zero in the direction of 90 degree. Besides for the case that gob water being in front-right of roadway head, the highest amplitude of vertical response component appear in the direction of 45 degree in the right, however the zero amplitude points of horizontal response component appear in the direction of 45 degree in both sides of left and right of tunnel. Nonetheless, the ghost can be removed by contrast between the vertical response components. Based on numerical simulation, application of miming indicates that integrated interpretation using horizontal and vertical component can obtain reliable results. Therefore, it is feasible that using multi-components transient electromagnetic response to prospect gob water, and it provides a new idea for using miming transient electromagnetic method.
