It is evenly equipped with electrode in the tunnel in face and receives line, electrode receives the end of line and the signal receiving end on electric method meter is connected to one
Rise.
5 electrodes are evenly equipped with the ground near the underworkings of down-hole driving face and receive line.
A kind of multi-faceted DC electrical method advance geology exploration method of driving face, comprises the following steps：
The first step, on the middle position of the getting working face of underworkings lay DC electrical method detection electrode, by direct current
Electrical survey (-ing) electrode is electrically connected with the direct current supply terminals on electric method meter；
Second step, 5 electrodes equably laid on the ground near the underworkings of down-hole driving face receive lines,
The end that electrode is received line is linked together with the signal receiving end of electric method meter；

A kind of multi-faceted DC electrical method advance geology exploration method of driving face, comprises the following steps：
The first step, on the middle position of the getting working face of underworkings 3, lay DC electrical method detection electrode 1, will be straight
Stream electrical survey (-ing) electrode 1 is electrically connected with the direct current supply terminals 6 on electric method meter 5；
Second step, 5 electrodes are equably laid on the ground near the underworkings 3 of down-hole driving face receive lines
2, the end that electrode is received line 2 is linked together with the signal receiving end 4 of electric method meter 5；
3rd step, by electric method meter 5, DC electrical method detection electrode 1 is powered, DC electrical method detection electrode 1 meeting
Produce a spherical electric field；
Electrical signals are carried out by the 4th step, the electrical signals sent back to by 5 electrodes reception lines 2 of electric method meter 5 reception
After analyzing and processing, obtain the geology detecting result in front of the driving face of down-hole.
